Rated 5 out of 5 by from 84,000 miles and counting. Built to last. Installed these tires in July of 2014. Have put 84,000 miles on them. Mind you, they are warranted for 55,000 miles. They have not reached the minimum tread wear yet. Never blown out. Never had a flat due to tread puncture. Although they have had tread punctures, they still hold air. They are as noisy as you would expect off road tires to be but I have heard worse. I've been through ice, extreme heat, rain and snow, harsh desert terrain with these tires, on and off road. They perform great in every situation. Highly recommended by me. Not only for you to purchase, but I will be purchasing them again if they ever wear out.

Rated 5 out of 5 by from Great all around tire! These are great tires! I bought them as a replacement for the worn out highway tires that came on my Tacoma. I'm an avid outdoorsman so I needed something that would hold up to highway use and off road abuse. These tires have never let me down! Wet and dry traction is great. In sand, loose gravel, dirt and snow these tire performed very well with minimal traction loss. In the mud the were decent but had a tendency to pack up, but that's pretty normal for any all terrain tire. After about 45000 miles on them they still have plenty of tread left so getting 55000 miles out of a set shouldn't be an issue as long as they are rotated regularly and inflated properly. The only real down side I see with these tires is road noise. Even brand new they would hum a bit going down the road. Now that they have 45000 miles on them they have gotten to be fairly loud. Just something to consider if road noise bothers you. All in all these are awesome tires and I will be ordering another set as soon as mine wear out.

Rated 5 out of 5 by from Excellent tire for the price I was looking for replacement tires on my 2012 Ford XLT. The factory tires were Goodyear with a highway tread, the dealer I bought the truck from was recommending another set of Goodyears or Pirrellies I checked out a couple websites and found these at Discount Tire. After getting looking at them up close I decided on the ATP good off-road traction mud snow sand loose gravel and even after 46000 miles still lots of tread left. I was never pleased with Cooper Tires in the past but these are night and day difference I will definitely buy these again when I replace the ones I have now.

Rated 3 out of 5 by from what did you say? 275/55r20 on a 2012 jeep grand cherokee. Handles well in all conditions. An easy 5 star rating. However, by far, this is the loudest tire I've ever owned. They hit a resonance point of my jeep between 40-45 mph and howl so loudly conversation and phone calls are impossible. I have over 300K miles on several models of cooper tires on several vehicles. I'll be looking at atw or at3 soon. I just hope they aren't as loud as the atp.

Rated 2 out of 5 by from Wears down to fast I purchased these tires from discount tire and was happy with them for a while. But know that I'm at the end of their life I'm very disappointed. I have only put 45000 all highway miles on them and they are worn out even though they are supposed to be a 55000 to 60000 mile tire. If these tire didn't wear out so quickly I would purchase them again but I didn't even get close to their supposed life span.

Rated 5 out of 5 by from Super long life, excellent on and off road capability I bought the tire because of other reviews. These tires have great mileage performance. Superb on and off road capability. We have a set of these on my wife's truck and now have 55000 miles on these tires and they have 8 - 10/ 32 tread left.. , i also have a set on my 4x4 hunting truck that spends more time off-road then on road. They hold up to any abuse. When they finally wear out we will be buying another set FOR BOTH TRUCKS. You can tell when it's time to rotate cause it starts hum going down the highway.

Rated 1 out of 5 by from Thread separation on 2 of 4 tires purchased set of 4 tires 5-25-12, rotated and balanced as indicated. First Tire went bad At 29, 500 miles. although a second tire was showing same crack along the edge of the thread, Discount tire advised that was normal. Prorated and charged accordingly for a new tire. At 34,727 miles the second tire with the "Normal Cracks" also had thread separation. Got that one replaced. now at 40,000 the other tires are showing the same normal signs. tire has a 55,000 mile warranty so Aside from that huge Hazard tires are good.

Rated 5 out of 5 by from Superior tire! Went to buy tires (LT265/70/17), first 3 sets of tires they brought out were all foreign made. I asked for some made in USA. They brought these out and I loved the way they looked. E rated, met my requirements. This was the second set of tires on the truck from new. I have 80,300 miles on the tires and still have a little life left in them. When balancing never had to use much weight. I tow occasionally, car trailer, and the sidewalls have held up nicely. I'm looking at put a leveling kit on and getting larger ones (315/70 r17) this time. Would definitely recommend!
