Review: 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!

great tire - good value long life-look great - delivered on time

### ⭐⭐⭐⭐ Very good tire
*by D***. on December 12, 2025*

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.
