The second set on my favorite lady's suv she has been more comfortable with the tires and I have been relieved. She drives 50 miles round trip in NE Ohio.
One of the best tires cooper has ever made. Ive have been buying cooper tires for a long time. 10+ years. ive had the STT, the ST, Zeon rs3-a, rs3-s, cobra, cs2, cs3, cs4, weathermaster, discoverer m+s, etc and these at3's are one of the best. Right now they are on my 2015 f150 supercrew 4x4 and have been for 20,000 miles. the tires still look new, even with the occasional burnout (cause i keep them rotated). they are super quiet at highway speeds and even at 100+ mph. they handle excellent on drive payment, i can take 35mph corners at 60 with only a little sequel from them. which is impressive for 5500lb truck. even in the rain i can still take the same corner at 45mph but after that the front end looses grip and starts pushing. In the snow they are 10x better than the old hankook dynapros that came on the truck. they provide tons of grip in the snow but not too much that i cant drift it and in 4x4 with the diffs locked i can push snow with the front bumper. ice is where they seem to fail but that is expected from any tire without studs in them. Highly recommend you get these if you have a truck
Great all season traction. Especially winter. Wear a little faster than expected with scheduled rotations. But overall a great tire.
By far the best money I ever spent on tires would never buy another brand again best tires I ran on my f150 since I owned it
We have only had these tires for a month with about a thousand miles on them. So far I am very pleased with the tire quality and build. They have only been test on dry road and have performed very well on the Suburban. I am very interested in how the tire will perform this winter. Overall I am very happy with the tire but can only comment on their performance on dry road.
I can't say for sure about winter because it was ending when I installed them, but there was some snow. These are good on dirt roads. My last tires sunk in and moved in the flow of the mud. These stay in control on dirt. I am still not going as fast on dirt as other traffic because there is some kind of crunching that the car didn't do before: maybe It is the shocks, as I go over various rocks and bumps. Rain driving has a slight hydroplaning but it is better than my last tires, which were good ones. It gets windy here. Braking is good. Overall good choice for farm area.
Fantastic company with all questions answered quickly before hand by multiple people glad to get the business. Shipping was one day ahead of schedule and was free. Will use from now on.
Was not impressed with snow traction, but I have had Nokian AT Plus tires. Snow traction diminished about 1/2 tread. The tire did great on dry pavement right up to the 63k miles where I am taking them off. They have 4/32 tread left. They are now dangerous on wet pavement. They was great on wet roads when newer. Mud traction was on par with most all terrain tires, anyone that says all terrain tires are good in mud has never had mud tires. Hard pack, rock, gravel, tires performed fine. Fuel mileage suffered very little over the stock Goodyear's highway tires that came on the ram 1500 4x4 eco diesel. I drive between 1000 to 1600 PER WEEK. 600 To job site and back home on interstate. I do power line work in the Appalachian mountain range. These tires have been used off road with no failures. Cooper has a winner here.
