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!

Very good tire
Very happy with these tires. Good ride for a load range E rugged terrain tire. Was impressed with snow traction. I did not even have to engage 4WD on a snow covered steep hill in a relatively light weight Gladiator Pickup. Ice is less good, but to be expected. Fuel economy dropped, but I increased diameter over 2 inches and moved from a highway tire so to be expected.

Good buy
These look great on my truck and no road noise. I have already used them in light snow (6") and they did well.

Great tire
Amazingly quiet tire on the hwy and great handling 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.
