Great tire
Have these tires on my 2020 3500 Denali dually, great ride quality and very minimal road noise. Have around 55,000 miles (mostly towing a 40' flatbed gooseneck) on them now and they are about 30% tread. Will be buying the same tires again!

Perform well and quiet
Purchased these in 35-12.50r20. Balanced perfectly, smooth ride, performs well in snow and rain. Will buy again.

The only complaint I have about these tires is ; they get flat spots from sitting a day or more. They were hard to balance to begin with and after getting them as good as it gets, they get flat spots after a day or so of not driving my truck and then of course you have to get them warmed up before you get a smooth ride. Price, Value, Looks, Functionality ; everything else is on point!

Great tire
Amazingly quiet tire on the hwy and greathandling on wet road conditions even though this Cooper all season tire has an aggressive lug pattern. 100% satisfied with my purchase all though I have less than a 1000 miles on them.
