Cooper Discoverer AT3 tire review

I picked up the summer issue at my local Barnes and Noble a couple of weeks back... sorry, I should have noted that the link only takes you to the OJ website, and not to the article itself. If you want to subscribe, I think you can do that online and you then read the journal via iTunes or iBooks (or your favorite Android equivalent) each quarter. It's a pricey subscription, so you may just want see if you can find it at your favorite local book store or newsstand. It's a cool magazine, and a refreshing change from the usual Fourwheeler, etc. rags out there.
 
I just had 275/70-17 AT3 put on my 2010 4Runner (on Konig Countersteer X wheels) and am having serious balancing issues. At right around 50mph it becomes very noticeable so I took it back to Discount Tire yesterday and asked them to re-balance. They tried and failed, even after switching from stick-on weights to a static weight. Their suggestion was to switch to a different tire, which I'm hesitant to do, but the current situation is intolerable.

Have Cooper replace the one that won't balance. They should back their product. Let us know what happens and if they treat you well, kudos. If they don't, then we know what to watch out for.

I have towed my 14' landscape trailer about 2500 miles and my 16' enclosed trailer about 3500 miles on the highway in 2014 alone with a number of local miles towing as well and these tires continue to serve me well. I do enough towing that when it's time to tow my camping trailer I don't even think much about it since it tows like a toy compared to the enclosed trailer loaded up to 6000 lbs. I think three of the trips I did (about 3500 miles worth) were when daytime highs were topping at 100+ degrees.

As much towing and as little off-roading as I've been doing recently if I were buying tires today I'm not sure I would have chosen a tire like the AT3 that's clearly aimed more at the off-roading side of things but I have yet to be disappointed with these tires.
 
Any way to read the article online?

Here is the article, really well done review, IMO:
Where the Rubber Meets the Road | Expedition Portal

Does anyone know of some sales going on with these tires right now? Perhaps a discount code or something? The best deal I've found is on TreadDepot.com, but shipping to PNW is as much as one of the tires, which basically makes them the same price as everywhere else. I want the C load, 265/70/17s.

How about $190/tire shipped plus a $40 instant rebate Ratings, reviews and specifications for Cooper Discoverer A/T3 tires
 
Being a mobile electronics installer, I get to talk to a lot of fleet mechanics and every single one of them has told me never to buy:

-Cooper
-Kumho
-Continental
-Falken
-General
-Hankook

I have a Scion that came with Falken tires...they were garbage. Had to replace them in less than 2 years. Went to Yokohama W4S All-Seasons and they did okay. After those went out, I went to Goodyear Eagle GT's and those are fantastic.

Currently running BFG Rugged Terrains on my 4Runner and I don't like them. They love collecting rocks and then they throw them. In rain, they are fantastic. Have never hydro'd in the BFG's and they are quiet and the ride is comfortable with no vibration. They do pull a little bit to the right in my 4Runner. We verified with a set of street tires that the alignment is indeed correct.

I can bare with these until they need to be replaced. At that time, I'll probably add wheel spacers and a spacer lift to put on some 285's.

If anyone was able to read through all my rambling...I am wondering if Dick Cepek tires are any good. I really like the aggressive tread on his tires.
 
:hand: Pump the brakes.... I have to STRONGLY disagree with you on this one... My AT/3s are top tier. handle great, take rain great, off road great. they are quiet and have tons of traction at a very comfortable 40 psi.

Fleet mechanics are not putting at/3s on their fleet vehicles. they put tires that are designed for industry, E rating, highway tires, or commercial service vehicle type tire. General Grabber is another great tire for off road, guy I worked with threw a set on his hand-me-down CRV, god it was hilarious to see him cruising on the easier stuff at the OHV Park........ so I am just not seeing the evidence that either Cooper or General have a bad rep... Facts before you sling something like that.

Every company has a terrible tire or two(Cooper use to be known as the budget brand), whether it is their budget brand or a tire that is straight awful, but the title of this thread is Discoverer AT3 Review and you targeted Cooper and General going off of what "every fleet mechanic" has said to you. :mad2: You're not reviewing the tire, nor are you providing anything constructive, Do YOU have any experience with Cooper AT3 or the General Grabber AT2???? :flame::flame::flame::flame:

I would challenge one of these "mechanics" to get approval to put AT/3s or GGAT2s on their fleet vehicles. There is no way they would get approval for this. It is not economical, they wouldn't last and they straight up are not designed for that application. So, this brings me to how does this even apply to the AT3 or GGAT2???

In comparison. my bfg Ats(not the 2s) were god awful. hard as rocks (35 psi), picked up every rock I ran over and handled very poor in the snow/ice, they did not clean themselves worth crap. they became so hard packed with snow and ice chunks it was almost as they were bald. I did have balancing issues with my BFGs, this was multiplied by the fact my UBJ was looser than a broken N64 Controller. frankly the compound is really designed for gravel roads and desert, which they were very beastly on the trails. Cooper At/3s have more and deeper a siping, the groove pattern is more parallel to the tire and this is designed to keep the tire tracking straight in snow/water. Compare the BFGs, they almost have no parallel design to their groove. I would say BFG slightly superior trail qualities, I think they well fair better dealing with trail damage than the coopers, but cooper has superior road manors, especially freeway manors. my BFGs... well did whatever the hell they wanted to do haha, cruise to the left for alittle, now maybe to the right, definitely a product of worn suspension parts and the tires. after I rebuilt the front end, I had only a marginal gain until I put new meats on. But I think that was just because there was no saving the BFGs once the damage was done...

Had to special order mine from Americas Tire when I lived in California. The tire jockeys there threw a few compliments toward these tires when they were throwing them on. They keep BFG ATS in stock all in my common size, 31/10.5/15, but he says he gets roughly the same amount of orders for the Coopers as the BFG, they just do not stock them for some reason or another. He thought they were a great tire, has a set on his taco.

For the record I do agree with you on the Eagles :hug:. I have eagle f1s on my miata, and those are smoking tires. Mine are about dead, cracking after 4 years, and they still have close to 40% left on them. My other set, before they changed the tread pattern went just about 4 as well

Boss puts cooper at/3's on the work trucks. E rating only. I work in the oilfield in south east new mexico, full of greasewood, mesquites, and cactus, and everything else that is not tire friendly. Plus working around sand dunes, low water crossings, mud, and ice. These tires have never let me down.

In my eco-boost, i put 30k miles on the tires, not one flat in the field, not even a low tire.

I plan on putting a set on my 15 4runner next month. I need the e-rating, anything under a 10-ply here is a no go.

I'll update post with pics when installed.
 
I wished I found this thread before I spent forever researching
I will first say that I spent hours and ended up with a list of about 9, then narrowed it down to about 4. I then waited and over a couple weeks I tried to find people in person who had the tires on my list, looking everywhere I went. I was lucky enough to find a couple of them and talk to the owners and listened as they drove off, which helped me cross them off my list.Then I was down to 2 and when I remembered that the Coopers were made in the US, I pulled the trigger.
I got a set Cooper Discoverer AT3. They are much quieter than most, handle surprisingly well, have deeper tread than almost all their competition, made in the US, look cool but not overly aggressive and do great off-road. Oh and to top it all off they do alright in the mud. In the reviews I read by pro testers they said these were the only AT tires they tested that did an ok job in the mud. I can attest to the truth of this, except for the time I went through sloppy mud and then right into deep sand. The only time I was ever stuck.
They do still sell these and I can not recommend them more. I will say that I would rather have a set of 33s on 17s but since I still have my old 15x10 mags and had to get the 31.5" models, my tire shop had to order them. But it was worth the wait as they were even cheaper there than I could find them online and I got a lifetime, full replacement warranty for all 4 tires for something like $82! Beat that.
So, if you need a new set of A/Ts, get the Cooper Discoverer AT3 tires and waste no more time researching. And if if you have an America's Tire by you, get them there. You will be so happy you did.
