Gear Review: Cooper Discoverer AT3 Tires

Sweet new tires! Fat - but not ridiculous - lugs!
30,000 Mile Update for these tires (click here). 

This blog has been online for nearly four years.  Over that time, I have gotten hundreds of requests for "reviews," ranging from vegan beef jerky to deep sea super-heavy fishing tackle.  I answer each one, usually with a "thanks, not interested."  Not because I'm ideologically opposed to getting free or discounted gear and reviewing it,  but because I'm not going to waste my time or yours reviewing a product that I wouldn't normally use in my scope of outdoor activities (which is pretty broad, mind you).

So about a month ago, I was quite pleased to receive an email from the ad agency representing Cooper Tires.  They said they had read the blog (most vendors haven't), noticed that I own a truck (again, most vendors don't spend the 30 seconds needed to figure that out), and that they'd like to send me a set of Cooper's new A/T tire, the Discoverer AT3.  They were also sending an HD flip cam (for me to return to them) containing footage of the tire install and the "field tests" we had run the tires through.   Ostensibly, the footage will be used in some new ad by this ad agency.  And ostensibly, they are sending the flip cam back to me.  We'll see.

I told the ad agency point-blank that I am not an off-roader, but that any active sportsman needs good tires, and with that in mind I would test the tires out on the types of off-road conditions most commonly experienced by anglers, hunters, surfers, paddlers, etc.  The kind of conditions that a 4WD 1989 S-10 with good tires can easily amble through, but an F-250 King Ranch with stock tires cannot (oh, I've seen it).  Specifically, tall wet  fields (grass, corn, etc), abandoned timber roads, wet sand, wet gravel, and high speed turns and braking on sand and gravel.  And of course, let's be honest - highway ride.  Because most of us on the east and west coast are  not going to get offroad until we get 20, 30, 60 miles up the highway.

On looks alone, the AT3 is a great looking tire.  It doesn't quite have the super aggressive look of the BFG A/T (my offroad tire on my last Tacoma), but has more of that same look than the comparable Yokohamas and Nittos, and most importantly, the tread is pretty darn deep.  No beating around the bush there.

Highway ride.  This is important because I spend a lot of time on the road inbetween work sites, my office, my home, and outdoor rec sites like the farm.  My 2010 Tacoma has the TRD Sport package which means 17" wheels and LS rear diff (vs. the TRD Offroad - 16" and rear locker).   17" means a standard 31-32" tire.  Not a small amount of rubber.  And with offroad lugs, you can expect some noise.  Up to about 65mph on the highway, the AT3s are silent.  Around 72mph the noise gets noticeable, and at 80mph it is loud.  This is definitely in line with other offroad tires, and actually is a good reminder (to me) to slow down and take my time. 

Timber/farm/beach access roads.  "Access" is the key - and let's be honest, folks - this is the main use of your offroad tires.  Sometimes the roadbed is great material, sometimes it's not, and sometimes there's a giant gully with rushing water, running right down the middle of it.  You need a good tire here.  We tested breaking and acceleration on several different substrates (packed gravel, loose gravel, wet sand, abandoned clay roadbed).   We worked really hard to find a problem with these tires.  We couldn't - they performed wonderfully. 

Another key reason you need a solid tire on these off-pavement access routes is the nasty two word phrase we all fear "sidewall puncture."  With street tires or bargain "multi use" tires, the thin part of the sidewall begins an inch or less from the ground.  Not counting however deep your tires are sinking into the roadbed.  The good thing about real off-road tires like the Cooper AT3 is that the tread extends several inches up the sidewall.  Does this mean you won't get a puncture from that 6" landscape nail? No, but you're less likely to have a complete blowout that very moment, giving you time to get back on the road and most likely get to a tire repair place (where they give you the bad news).  I trusted my previous off-road tire (BFG A/T) for this and it never let me down.  My previous street tires on both the 1996 and 2010 Tacoma? I never trusted me, and they still let me down.  Punctures, gashes, flats, and blowouts.  Never trust a street tire on a farm.  PS, Bridgestone Duelers, I hate you.

The only "realistic" test I haven't yet put these tires through is the loose, deep sand run (i.e. beach access).  The AT3's are magical on packed sand, which I hoped and expected.  Maybe we'll see soon  how they run in deeper sand.   

And the only slight concern I've had with these tires yet has been that they need regular inflation, like most truck tires that get "worked."  If you run any off-road tire frequently on the highway, you need to keep up with  your tire pressure anyway, but I've found that the AT3 is not exempt from this standard.

This is a solid tire.  In a way, it's a shame that Cooper didn't get it on the market sooner, because their main competitor, the BFG A/T, wasn't available for many common truck wheel sizes just 18 months ago (and the AT3 is hitting the market in those sizes and several more).  However, I think Cooper fans will like this tire, and I think BFG, Nitto, and Yoko folks should take a real hard look at this configuration.  I don't think you'll be disappointed.

Disclaimer: Courtesy of Cooper Tires and the Zimmerman Ad Agency, I received, at the cost of tire disposal only, a set of Cooper Discoverer AT3 tires to try out and review. However, this review contains no bias. Had I not liked the tires, I would not have even posted a full review on this blog. Had I thought they were mediocre, I'd let you know that too.

Thanks for this! I will have to but a set of tires soon for my Jeep Wrangler. I was automatically thinking of the BFG AT's, but I may have to check this tire out. I'm with you on the Dueler's. I only have 25,000 miles on the Jeep and the tires are already showing serious wear!

tugboatdude said...

I can say from riding in the truck and watching them perform,he wouldn't let me drive,that they are a wondeful tire.Hey Swampy what's the going rate on a set of tires for the normal people?

Swamp Thing said...

I have a big wheel size but I believe that the MSRP was around $210/tire + install + disposal/taxes. I seem to recall on a tire website (that I found while researching the tire) that they run something like $180 - 250 depending on size.

I don't work in that industry, so I don't know what consumers usually pay compared to the MSRP. So this could all be totally useless information. What I do know is that for my wheel size, $200-225 (on the wheel & out the door) is (sadly) a very reasonable price.

Those crap Duelers were also $210 each (I found out after the first puncture).

Barrett said...

Have you tried this tire in dry sand yet? I am considering installin a set onto my 95 Jeep Wrangler and live in Florida so any info would be appreciated.
Please send your reply to:

Thanks!

Alex said...

Hey I just purchased this tires from a Geralds Tire center and got 4 tires for $680 with install and takes all included and what not. So it ended up being only 150 a piece which isn't to bad for my Jeep Wrangler.

Brenda said...

thank you for the review, being a girl, I shop for tires first by how they look and this is a good looking tire, but I like the deep tread and need something all weather for my Jeep Grand Cherokee because, lets face it, its a Jeep and I better be able to get through anything, that's why I own a Jeep! I had already made up my mind to get these when I found your review, now I have a second opinion, thank you again.

RyanH said...

This review was awesome. I was recently promised some Nitto Terra Grapplers and when I went to the shop to pick up my F-150 I see these Cooper's sitting on my 18 Stock rims and was rather disappointed. The owner of the shop told me there was a mistake at the parts dealer and he gave me these, said he had never used them before but knew the Nitto's on hwy would need to be replaced after about 15,000 miles. After the first weekend with it I drove them around 300 miles and loved them on the hwy. They were really smooth and quiet and look really aggressive. I haven't had the chance due to our drought to take them out on the wet clay roads of my youth, but after checking out this review and comparing the intensity of the tread to my old BFG's I'm excited to see how these things perform.

Hip1 said...

Thanks for the review. May I ask what size you chose for your Tacoma? I have a 2008 Tacoma TRD.

River Mud said...

Thanks Ryan and Hip - hope you like the tires. Hip - mine are 275 17s.

They've done just as well as my old BFG AT's on my old Tacoma. I've been pleased with them!

Anonymous said...

Sorry if I missed this somewhere one the page, but what exact size were your AT3s in the review? I saw 275, but were they LT or P-Metric, and did you have a chance to measure beginning tread depth?

I'm really thinking hard about these Coopers after my original choice (Revo 2s in LT) went up almost $70 per tire when the rebate came out.

I really want something that has nice deep lugs in a P-Metric and the AT3s look to have exactly that, but I'm having a hard time finding specs on the tire.

Also, how are they on wet pavement specifically? Hydroplane resistance, etc...

Thanks, and great review.

I just bought a set of 235/75/15 for a 1992 ford explorer, I paid 536.75 out the door. I couln not be happier. I live in Asheville NC. These tires carry a 55,000 mile tread wear warranty. Great tire for the money... Oh cooper is offering a 75.00 doller rebate when you buy 4 of these tires.

Hip1 said...

Do you have a lift? I would like to get the largest size tire that will fit without lifting my truck. I know that the 265/70/17 will work but I was not sure if the 275/70/17 would without rubbing.

River Mud said...

No, you're right. I called Cooper and asked them, and they said the 275's would rub - barely. I have the 265s. Pretty big tire.

River Mud said...

LC - sadly, I have no idea of the exact size. Sorry! They are great for hydroplane resistance.

Anonymous said...

This review was very helpful, thank you! Cooper, if you are reading, this review helped sell your AT3 to a new customer.

I had to laugh about your F-250 King Ranch remark, as I just put these tires on a Lariat, FX4, F-250 Diesel. They replaced the stock tires (I'll let your readers go figure out what those are, here’s the info – 2006, Crew Cab, F-250, FX4, 20” tire option). I don’t drive this vehicle that often, so I had a couple of years to do plenty of research and make a non-rushed choice. None of the other tires available in this size were quite hitting the mark. These seem to hit it perfectly for what I want to do – lots of on road traveling, some off road, sand (beach), and farm/grass (wet) un-maintained roads. I’ve only had them about three weeks, so I can’t offer anything other than wet traction and road noise feedback – thumbs up to both of those!

Cybdiver said...

Lucky you to get a set of wheels. I ride 50/50 Just going home takes me off road and on a hill 25% incline rock climbing. If they have any interest in further testing please give me a call

Hip1 said...

I got my AT3’s yesterday and I am happy with my purchase. I have a 2008 Toyota Tacoma TRD sport 4WD. I replaced the Bridgestone dueler HT 265/65/r17 with 265/70/r17. The slightly larger improves the look and ride of the truck. Thanks for the review, it closed the deal for which tires I decided on.

I have a 2005 Silverado 2500hd. I had a leveling kit installed on the front end. Then I had Discoverer AT3's 285/75/16's. I was a die hard BFG fan most of my life, 45's. I have had performance tires on my Corvette and AT's on my trucks. The Cooper tire is great, nice street ride. I have also uses them off road to get my dirt bikes to the trails. I will by again and have recommended to my dad who is looking too. Way to go Cooper. Oh, I got a great deal, 410 apiece.

Your blog helped! Husband has cooper ATR tires on his Chevy 4x4 1500 & I need new tires on my 1995 Tahoe. Wasn't sure about the AT3 but will now be buying them. Can't wait to try them out on the snow in an Iowa winter! Using the 265/75/16, getting them for $170 each.

Anonymous said...

I just purchased a of these in 265/70/16 from tirecrawler.com at $125/tire and with shipping to Arizona $145/tire, also got a $75 rebate. Looking forward to trying them out, they seem to be getting great reviews

Sandie & Cliff said...

I was just wondering if the tires reviewed were 4 ply or 10 ply? I have a Chevy silverado 1500 4 wd extended cab short box and am thinking to get the 4 ply and was wondering if you think that it will be good enough. Thanks in advance.

I just bought 4 AT3's for my 2002 Ranger 4x4. $75 rebate and buy 3 get 1 free, I paid about $400. So far I love them. It was because of your review, that I decided on them. Can't wait for deer hunting to try them off road. Keep up the good work, and thanks alot.

DenBud said...

Just ordered a set of 275/65/18 for my 2008 Toyota Tundra. I was looking for the "right" tire for some time and this blog verified my decision to try the Cooper AT3. I like the look and tread pattern of the tire. Can't wait to throw my factory installed Duelers in the scrap heap! Winter is coming here in MN and trust they will perform well in the snow. Ordered them on-line for $784 including tax and shipping, not including the $75 rebate, which I think is a great deal for a quality brand like Cooper. More to follow.....

River Mud said...

Those factory Duelers sucked for sure!!!!

Anonymous said...

Just put them on our 3/4 chev 4x4 HD .....very nice ride so far. Had Nitto's terra grapllers last. They just wore out way too fast. So I am excited for our MN winters and hauling the snowmachines to any where we want to go.....went wit the 245 stock size for now. maybe get some rims and go BIG on the next set...

Glad I found this blog. I’m considering Cooper AT3’s for my 1977 Ford F250 4X4 and got a lot of great info here. One more question though, does anyone know if they are bad at picking up small rocks or gravel? I live on unpaved country road and that can be a real pain. Thanks, Dan

River Mud said...

Dan, surprisingly, no, they don't chuck a lot of rocks compared to my old BFG AT's.

Dan said...

Thanks for the help on the Cooper AT3’s. I had a set put on yesterday and although I haven’t worked them yet they look good on the truck and ride great on the road. Went with 265 75R 16’s for my ’77 F250 4X4 flat bed. Dan

gizmo said...

I just put a set on my 2009 F350. 275x70x18. They are extremely quiet on the city streets. Were great in the rain and probably will have the first test in the snow by next weekend. I had conticraps on it before and couldn't stand them. Huuuuge difference............

DenBud said...

My new AT3's are installed and I have been riding on them for a couple of weeks now. Great ride and amazingly quite for a tire with such an aggressive tread pattern. Excellent value for the money. Bring on the snow!

spinlake said...

I have had 3 different sizes of the BFGs AT/KOs on 3 different trucks and every set had sidewall failure. I had a set of the cooper STTs on a V6 Ranger 4x4 and they were the best. I went through hundreds of yards of deep mud and snow not even using the 4 wheel drive. Cooper builds a great tire I am looking for a set to put on my F150 supercrew just may give the A/T3 Coopers a try.

Daniel said...

Any comment on how these tires perform on snow and ice? I am considering this tire as an all-season option for getting around the mountains of Montana and Idaho this winter in addition to off-road access in the summer.

Daniel said...

Any comments on how these tires perform on snow and ice? I am considering these for all-season use in the mountains of Montana and Wyoming for access to backcountry skiing and hiking destinations.

River Mud said...

Snow and ice - don't know yet. We recently had an ice storm that left a 6" pile of wet slush on the road and the AT3's did fine, which I would expect of any truck tire except a straight street tire.

Anonymous said...

I live in MT, and I have finally got to try them in some snow and slush, and I must say they perform really well. Off course wet ice no all season tire can measure up to siped studded tires. But the new AT/3 is a pretty awesome all-round package on my 2000 Chevy Silverado 1500 std cab 4x4. They are quiet, tracks nice and have very good snow-slush driving properties. I have 6k miles on these since the summer. Highly recommended for the money.

Just put a set on my 2009 Colorado. Got rid of the Bridgestones. Truck never rode better, on road and off road. So far a great tire.

Victoria said...

Thanks for the great review. You've helped me make the decision to buy the AT3s for my F150. I'll be out looking for the best price TOMORROW!

Anonymous said...

I went to the AT3 tires last month, after my AT's wore out after 30,000 miles.
The AT3 tires are like the old nylons from the 60's!
They sound like the drive shaft is going to drop for the first mile, until they warm up!
Would not buy Coopers again!

River Mud said...

Maybe you got a bad tire, or a bad set? I've never even heard of something like that! (to be fair, I'm 37 and don't remember offroad tires before about 1985).

That just sounds odd, for a modern tire at least.

Doyle said...

Thanks for the info, installing 275-60-20s on my 08 ram. This week.

Thanks for the reviews, getting ready to install 275-60-20s on my 08 dodge ram.

Seems like tires of a monster truck to me. I'll keep visiting for more of your interesting post. Keep it up.

Thanks for doing the review!

I am needing new tires on my F150 which currently has the Discoverer ATR on it. The AT3 is replacing the ATR according to my tire dealer.

In all honesty, I am not surprised at anything you reported back about this tire. I have had 2 sets of the ATR's on my truck with absolutely no remorse. Both sets lasted 50k with mixed driving.

Luke said...

These tires are great! Just bought 4 new 10 plys for my duramax because one of my front bridgestone duelers came apart for no apparent reason driving 30 mph on my street. Glad I wasn't on the highway!

Dean said...

Have enjoyed reading this review and comments. Currently looking at the AT3 to replace a set of Michelin MS on my 05 Dodge CD 4X4. I do some towing of a 10K pound camper and the MS do a great job but suck if driving on anything but paved roads.
After looking at specs on AT3 it has 2 poly ply sidewalls on the E load rated tires with 2 steel, 2 poly, 1 nylon on the tread, although rated same load as a 10 ply tire the plys don't add up.
Need help understanding this!
Don't want to tow 10K with rear end walking around every turn on soft side walls.

Anonymous said...

Read your 10 ply rated Michelin MS tires, very likely they say 2 ply poly, 2 steel, 1 nylon... or 2 poly 3 steel depending on the year of the tire.

"10 ply" is a ply "rating", not a physical count of the plies...

Modern materials make 2 plies of thick polyester equal or exceed days gone by cotton and natural materials. All major brands Load Lange E "10 ply" tires are either 2 or maybe 3 physical sidewall plies

Anonymous said...

Just purchased a set of 235/80/17 load range E for my 07 dodge dually. Ran atr on first set and got nearly 100,000 kms out of them. That was hauling 20,000-26,000 lbs on trailer with proper rotation . I don't think I will ever go to any other tire after my cooper discovery! Have been in snow and icy surfaces and no complaints. They ride smooth on hwy and are quiet up to 110kph with little noise after. Would highly recomend these to anyone. Cost was $1620.00 on truck all six out the door.

Dean said...

After reading this review and several others I purchased a set of 265/70/17 E for my 05 CTD Dodge. Smooth ride, quite, yet firm control even at 60 psi, even with an aggressive AT tread, off to good start. Replaced original equipment Michelin MS and that is what I'm comparing with. Cooper AT3's ride and handle the weight of my truck as well if not better than the OE Michelin's and 40 bucks per tire cheaper. Will report on towing when camping weather returns, but with 1/3 more air pressure they should do great. Thanks!!!

GaryB said...

I was debating between a highway all season and an all terrain for my 05 Prerunner Tacoma (265/65/17). I don't need AT's, but we get some snow here in Port Orchard (just West of Seattle, WA) occasionally and thought some extra traction won't hurt, plus they "look" like a truck tire instead of a minivan tire. It is a nice looking tire.
That was my mistake. Since buying the tires, we've had 2 frosts plus a couple days of heavy snow. I don't go out in the snow with this truck, but during the frosts my truck was all over the road. It hasn't rained in days and overnight got to about 33, with real feel around 25 (according to accuweather). Not extremely cold at all. No other cars/trucks around me seemed to be having any trouble with whatever tires they had, but the back end was sliding out around a moderate corner going just 20mph. Also slipped going uphill on my way home under 30mph with low-moderate acceleration.
Based on reviews I've read about the OEM Bridgestones, I got lucky with them and got 75k miles before I started seeing this behavior on the same roads.
After some back and forth 'discussion' with BigO, they're going to give me a full refund on the tires and I'm swapping out for something else. I have no confidence in these whatsoever.

I'm putting 6 235/75-16 cooper at3 on my 1999 chevy 3500 4wd drw, I pull a trailer and the truck is often loaded. I'll let you know how they hold up. A high load rating really limits your choices of name brand tires, I have my fingers crossed!

I have been shopping for the last year trying to replace my PC X/AT. I liked these tires but the directional is a hard pill to swallow. It was great until you realize you can only go one way with a change and they're expensive to replace. Really appreciate this indipendent review. I will be getting a full set at the end of the week 285/70/17 E for my CRD 3500 QC 4x4. Keep up the good work.

I work at a Goodyear dealer in the four corners area. We can't keep the Cooper AT3's on the shelf. A great tire for a great price. Traction ratings are an average of 8 out of 10 across the board. With a 55000 mile tread life warranty....Thats hard to beat. I'm for sure going to put a set of AT3's on my 2000 jeep cherokee sport. Factory size is 235/75r15 but going up to a 30x9.50r15 6 ply. I would recommend this tire over BFG, Goodyear, Kelly, Nitto any day. If you are reading this and live in the 4 corners area stop by and I'll give you a good deal on a set!!

BTW, they're some of the few tires made in the USA; I don't know if that showed up anywhere already. Thanks for the informative review -- the Jeep's up for new tires soon.

I love these tires. They run quiet on the HGW for the tread design and they are great in the mountains. I've had them in the snow and musd, No problems.

Called up the local (BBB Accredited) tire dealer and was going to purchase the Toyo Outlaw Country A/T 2's but they ordered the wrong size. Tire center tells me they sell alot of these Cooper Discoverer AT3's and I should look into getting them. Over $100 cheaper too! Bought em after reading this blog. Thanx for the information!

Trying to decide between the BFG All Terrain TA KO's and the Cooper AT3's for my '01 Tacoma w/t TRD Off-road pkg (265/70R16).

My overall impression after talking to a few tire shops is that the TAKO's will last longer, maybe 60K-65K. Comments anybody?

I've also been told that the 10ply AT3's would probably be too much for the little 6 cylinder in my Tacoma and I should go w/t standard 4 ply version. Is there really much difference between the 8ply TAKO's and the 10ply AT3's? Comments anybody?

Just today I replaced a set of Firestone Destination A/T's with 4 new Cooper AT3's on my 2007 Nissan Frontier 4x4(97,000 miles). $649 out the door and they said they would send in the $75 rebate (expires Nov. 6). The Firestone's had 47K on them and were getting really loud although not as loud as the orginal BFG's it came with at the same mileage. Otherwise I had little to complain about with them except for being almost down to the wear bars. With a Michigan winter around the corner I decided to get the Coopers before the rush. I'm hoping their ice performance is at least adequate, that would seem to be their weakest feature. Several friends have these tires with no major complaints. My first impressions, they're certainly smooth and quiet. I'll check back after some inevitable winter driving. Let's be careful out there!

River Mud,

Are the tires still working out for you? I need to get a new set of tires for my 4runner for situations similar to yours and was how they are wearing?

Thanks!

I have a 1998 Nissan Frontier 4x4 XE. I bought a set of 255/70/15 which is an odd size and hard to find. I was wondering if anyone knew if they would fit well or rub? I have cooper MS 235/75/15 now, so I would think that this jump in size wouldn't make much difference. Getting an allignment too.

I bought 235/85/16 Cooper Discoverer AT3s for my 93 Dodge ton truck a month or so ago. I really like the traction in snow and ice and I think they ride and handle well with an empty truck, but the seem to wander prett bad at times pulling my stock trailer or with a load on the truck. What are anyone's thoughts or advice about this? Is it an air pressure issue? What is recommended for air pressure at different loads? I would appreciate any advice.

Just purchased a set of atr3's and i love the agressive look and very quiet ride for a beefy tire.I went with the white raised lettering and makes my Runner look bad ass.Cant wait for some wet winter weather ...lots of confidence in these tires.Go Cooper!

I put a set of Discoverer AT3 275/70R16 on my 2003 F-150 4X4 for a final total (tires, balance, mount, etc) of $620 (a set of BFG ATs were going to wallop me for $1,050!!!). These replaced a set of Goodyear Wrangler Silent Armor. I got 61,000 miles from the Wranglers (rated 50,000) but the roar on road was loud!
So far the Coopers are quieter than the Wranglers and do well on both dry and wet roads. We haven't had any heavy rains in a while and hence no standing water on the roads, but with the deep tread and the 3 deep channels that run the circumference of the tire I would not suspect much hydroplaning.
I haven't had an opportunity to get in the rough stuff either but am anxious to get off the beaten path and let these babied strut their stuff.

Excellent review! Ive alwayd been a Michellin guy, but am seriouslu considering buying the Discoverer AT3 instead of the Michellin LTX AT2. I have an 08 4runner 266/65/17s.
I drive in about the same conditions as you: a lot of highway, but off road here and there to get into lakes, hiking trails, etc. I definitely need at good AT tire.
I would suspect the Michellin to be a better better of a highway tire and last s bit longer, and the Cooper to be a bit better off road.
Any opinion on which is a better winter tire?
Also the Cooper is a sharp looling tire, the Michellin very plain-jane.

I have an 08 4runner sport with 265/65/17s on it. I have always been a Michellin guy, but am considering the Cooper AT3s.I drive mainly highway, but occasionally go offroad into lakes, hiking trails, etc. I need a good AT tire. Also will be using them in the winter so they need to work well on the cold/snow.
Anu opinion on the cooper discoverer at3 vs the michellin ltx at2? i would suspect the michellin to last longer and be better on the highway, and the cooper to be better offroad. the cooper is also a much better looking tire, which counts for something.

Just bought 4 of these tires for my Jeep Grand Cherokee. I am usually a Toyo tire guy but I decided to try these Cooper AT3s. They look awesome and so far run great. Very quiet on the highway. WAY TO GO COOPER. YOU HAVE A WINNER WITH THESE TIRES!

Good day,
my name is Ash, sorry for asking this over the blog but we're having a really hard time finding the right people. I’m from the social research company AFS in Melbourne and I’m looking for people in Australia who can take part in some brief paid telephone research about tyre performance.
As we’re looking for users of very specific tyre brands at the moment we’re just seeing if there are enough participants to make the study feasible.
If we get enough people to say they’ll do the study (we need at least 30), it will involve sharing your experiences about the performance of these tyres with us in a brief telephone interview that lasts about 12 minutes, for which we’ll reimburse you with $50 (via mail).
You should be eligible for the study if you use any of the following:
• Michelin Pilot Sport 3
• Goodyear Eagle F1 Directional 5
• Goodyear Wrangler AT SA
• Continental Sport Contact
• Dunlop Grand Trek AT3
• BFG All Terrain TAKO
• Discoverer AT3
• Yokohama Sdrive
• Yokohama Geolander ATS GO12
If you know anyone else who uses any of those brands who would be able to take part of the study, please let us know and we can try and include them as well.
If you’d be so kind as to help with this study please let us know by getting in touch with us:
Telephone: (03) 8789 4401

We just bought an '04 Jeep Grand Cerokee with a set of brand spanking new AT3's on it (225/75R16). Every other SUV we looked at needed new rubber right now or very soon, an added expense we simply couldnt shoulder. The Jeep is in amazing shape at 125k on the clock, and the AT3's really add to the great look. A friend of mine thought we had gotten $1000 worth of new tires with our truck! The overall excellent reviews definitely helped make the sale. We're very pleased with both the Jeep and the tires. The wet weather handling and braking are confidence inspiring, and the road noise is very low, especially considering the fairly aggressive tread pattern and look. I'm actually looking forward to our first good MN snowfall to really have some fun! No more worries about getting stuck just going to work!

Ash / AFS, sorry you are having trouble finding people, but I believe the main market for this tire is/has been the USA (maybe I'm wrong).

And I don't know if my experience is typical, but the last two times I did business with individuals in Australia, I never got paid or got the product I paid for. No thanks but good luck!

I just put ATV 275 70 r17 C on my Jeep wrangler 2009 4 door. They fit without rubbing on my stock jeep.

Bought a set of these for my suburban. I usually run BFG TA KOs' but thought I would try these plus they were $50 cheaper per tire. Highway ride was awseome. Dirt road was really good, wet grass was good. Havent had them in shallow mud yet. I think that they have just a little less bite then the bfg but the ride and road noise is alot better in these AT3s'
