Cooper Discoverer AT3 XLT All-Season LT285/70R17 121/118S Tire

Great tire! 4000 miles on them and still as quiet as they were when new. I mounted them myself and planned to get them balanced at a local shop. To this day they've never been balanced and are vibration free all the way to 70+. I'll keep buying them as long as Cooper keeps making them.

I've only put a couple hundred miles on them so far, but I put them through mud, gravel, wet grass, and a stream crossing and they handled admirably. They're easily the quietest AT tire I've had, virtually silent even at 80 mph. I'm really impressed by the manners on pavement, very grippy through takeoffs and in the curves. They felt a touch floaty on gravel, but nothing serious. Not as good as a dedicated mud tire in the muck, but I would class it as very good to excellent for an All Terrain tire. On wet grass it did extremely well, not aggressive enough to mess up the clients yard, but grippy enough to go slow without spinning out, same with the slick rock in the creek. I'm interested to see how these puppies do in the snow and ice this winter, but based on reviews and my experience so far I expect it will be good to excellent. Looks were secondary to my decision, but I have to admit they're a tough looking tire, at first glance you could easily think they were a dedicated off road tire and being an old fart with a white truck I like the way the raised white letters look too although I know that's not the thing anymore (don't worry you can put the all black side out if you prefer).

I have less than 1k miles on these tires at this point, wanting to get a quick review out there to help any buyers interested in this newer release! I had difficulty finding reviews on these. These tires are extremely similar to the standard AT/3, which is an already excellent tire. The additional features on the sidewall both look good and should perform better for off-road durability, which was never really an issue. On the road, these tires are almost silent when new, and ride very smoothly and seemingly efficiently. I would recommend them as one of the better tires for this price point! UPDATE*** I just completed a 5,000 mile tire rotation with my tires. I added a photo after wheeling the Daniel Boone Backcountry Byway. To this point, the tires are wearing very smoothly, riding quietly, holding their balance, and very capable off-road. I have had one puncture from a screw that was easily fixed with a tire plug. I still highly recommend these tires! UPDATE*** 10,000 mile rotation is great. Haven’t been balanced since initial installation, and have been off-road on multiple occasions. Still silent on road, smooth, with VERY minimal signs of wear! Buy them!

Second set of these tires I’ve had on 2 different vehicles. Low road noise as long as you have a good alignment and rotate on schedule. They last longer than most A/T truck tires. Good traction on all surfaces and they look good. Just wish they put white lettering on the 20” tires.

I’ve had these tires on my 2500 service truck for a few years, they ride smooth, they’re not loud, and they haven’t worn down much at all. As for balancing, I have double beadlock wheels with rubber inserts so I use balancing beads (also purchased on Amazon) and there’s a negligible shimmy every so often. Also, the shipper, Autoplicity, has fantastic customer service.

US made. This is my 3rd set of Cooper AT3 tires. Each set has lasted over 60k easily. I rotate my tires every 5k to 10k miles, or every other oil change. No hydroplaning. Decent on snow, good on mud. Much better and longer lasting tires than BFG All Terrains in my opinion. Update: Attached are pics after 40k miles. I expect these tires to last another 30k to 40k miles. Also, I go offroad once or twice a week for my job. I never get stuck with these tires. Screws and nails from jobsites won't penetrate these tires. I've plucked out several screws from the rubber tread that didn't penetrate the tires. No flat repairs at all. These are the best tires I've ever owned by far. Update/60k miles & last 2 pics: The tires still have a lot of tread left, however, they are noisier and there is some cupping- possibly due to my shocks. They still perform well and these are still the best tires I've owned and I'll buy them again if they wear out before the truck does. Update/84k miles & last 3 pics: Still the best tires I've ever owned. Still no hydroplaning and no flats/punctures. They don't handle as well off-road as they used and they're a bit noisy, but I still like them. I could probably get another 10k out of them before I hit the wear mark.

These Cooper tires are great, But they ship with FedEx, so there is no guarantee that you will receive your ordered tires. Once again, my order was messed up, and I had to go to the terminal to pick up my orders. Seller, I know Fed Ex is cheap, but please give us other options for delivery. As for the tires, they are great. They are quiet, the runout is very good, and they are easy to balance with minimum weights. The largest counterweight I had to use was a 2.5 OZ weight to balance them. The Good Years I took off had over 4 OZ on 2 of the 4 tires for comparison. Be warned. If you don't know, switching to an all-terrain tire will cause you to lose some MPG. Like any All-Terrain tire, you will lose between 2 and 4 MPG on average with all-terrain tires. But this being said, the tire quality is great, and it runs very quietly on my 2014 F150. They handle a lot better than the Passenger tires that the manufacturer installs. I would recommend them to anyone.

These tires look great and ride nice. I was a bit disappointed with the installation process where they were sent to. I ended up paying extra for them to be installed. Otherwise the service was good and they installed them quickly. Overall I am happy with my purchase.

Very good traction in dry or wet snow........ wide tire is hard to balance....ore than one attempt requiring the tire to be deflated and turned 90 degrees and re-balance.
