If you want the best tire for the buck!!
I have always trusted Cooper Tires... Never had a reason not to... I have these on my 14 Sierra All Terrain, and there isn't another tire made that can beat them... Their QUIET, even at 35000 miles, Wear is excellent for a heavy truck, and I rotate and balance them every oil change (5000) miles... I live in the desert, and have yet to have any complaints about their performance... They look great, and on my 20 inch aftermarket wheels, I went from 275 to 305's....

Smooth and quiet
They look good, and perform even better. Impressed with how well they did in the little bit of snow we had this year

Great Tire, Low Noise Easy to Balance
Great Tire, Low Noise Easy to Balance! Rides realy well and did not wear funny. I was able to get just under 40,000 miles out of them.

Great looks and surprisingly quiet
Purchased these for the E Load rating and aggressive looks. Was expecting increased noise from Bridgestone AT tires but no difference. I have put on 750 mixed miles and experienced 1mpg less average on these tires. Very satisfied.

Rough ride
Rough ride on roads that are not freshly paved, starting to make a good amount of noise as well.
