Customer Reviews

Rated 5 out of 5 by from Frustratingly Good 255/65R17. 32-months and over 20,000 miles with minimal wear on my Jeep Commander 5.7 Quadradrive 2. Quiet on road and unflappable off-road. Run higher than OEM pressure of 38 psi as daily driver. In the dirt air down to 18 to 22 psi to tackle Eureka Dunes and a week in Death Valley including Steele Canyon, Hot Springs, Tea Kettle, Playa, Cerro Gordo, etc. Handles all terrain without issue; rocks, mud, sand, washboard, and loose scree. 1000s of miles off-road with no hiccups, wish I could post videos and photos. I have no issue with wear, if anything they're frustratingly long lasting as I'm anxious to move to a bigger size with a new suspension for clearance!

Rated 5 out of 5 by from Almost the perfect truck tire I bought this tire for my 2015 1500 Silverado. I did a level kit and put 285/55R20 tires on it. This tire is amazing! Sticks to the road better then my stock Wrangler SR-A's, Hydroplane resistance is far superior...truck just feels more stable in rain at speed. Living up here in northern New England...I really wish the tires could get the 3 Peak winter stamp. They are really good in the snow...but could be better in NE heavy wet snow.. Maybe more sipes cut into the tread

Rated 4 out of 5 by from As advertised balanced AT tire When I bought my truck used,it had 54k miles, had the dealer put a set of P275 60 R20s on. Had the truck almost 4 years and am at 102k on the odometer. Two tires are at the wear bars, other two have a bit more tread. Rotated the tires <10k intervals. Have increased it to every 4k last few times as the tread has worn down. I am planning on replacing in a few months as winter draws near. Tire has performed well over the life of the tires. Traction has been superb in wet/dry/snow. Tire is a 50k tire like most All Terrain. Prior set was a set of Firestone Destination AT and got about the same miles out of them. Am looking at the Cooper Discoverer SRX a 70k rated hwy tire, Cooper ATP, Hancock Dyna Pro AT, and perhaps Toyo AT2. Why can't a A/T tire be made to last up to 70k? Highway noise has increased now that two tires are at wear bars as you would expect. Guess I got the life out of the tire up to the warranty... I don't do much off highway driving other than some gravel travel at a minimum.

Rated 5 out of 5 by from Great wear and traction; moderate noise I put 40k miles on these tires, and they still had more than half of their tread left (traded the car). They had way better traction than the Michelin's that came OEM. They also look great. That said, I dropped 1-2 MPG when I had these installed, and they were noisier than the OEM tires. I tried to manage and got some of the MPG back by keeping them around 38 PSI.

Rated 5 out of 5 by from Great handling tire for all basic types of terrain. I've only got about 3.5k miles on these ties, but compared to my stock tires that were on my truck, these are amazing. I used to break free just stepping on the gas in light rain, but no longer. I live in NY, so there is snow and ice in winter. No problems here. I drive with confidence. Just got back from a camping trip towing a camper in heavy rain, tires held the road with no slippage. Did some light off-roading (gravel, dirt, grass, mud) and there was never a concern about getting stuck. Overall, these are great tires. Oh yea, and they have a great ride on the street with no noise.

Rated 2 out of 5 by from Not Impressed all tires cupped with less than 12k on them. had aligned at dealer ship after install and rotated regularly. On regular matinence appointment the told me my tires where cupped and checked alignment. Tundra was still in alignment but all tires where cupped. went back to discount and they would not do anything for me. will never run a copper again.
