Purchased November 2015 for 2011 F250 4WD Crew. Tread lasted only 18000 miles before it was gone. Tread wear was very uniform across all tires. They simply don't last on heavier trucks.

I have had these tires for 40,000 miles with zero issues. I would give 5 stars but they are too pricy. I only put these tires on my trucks, 2 suburbans and now my ford raptor. Best tire for trucks ever

I bought K02's for my 2003 Superduty 7.3 Powerstroke at 211,000 miles. I sold the truck with 296000 miles and the tires still have tread. I will never consider another tire for my truck.

I bought these for my Jeep JK and was amazed at the offroad and street performance. They are very quiet on the road. I use these tires offroad at Moab and at a Jeep Jamboree.

Bought four of these tires and am very impressed. Not a sound coming from an all terrain tire , smooth riding , also noticed better gas mileage . Best tire I've ever had .

Purchased one year ago today. 18k miles later and still in great, quiet and perfect condition. Barely lost any tread according to the tire shop that does my rotations every 4k miles. Very happy!

While I enjoyed the tires while they lasted, it was extremely short lived... @ 20,000 miles I'm in desperate need to replace. With no warranty & statements that they'll last 60,000 miles- I'm not looking at buying these tires again.

I replaced my factory tires with these bad boys on my 2016 Chevrolet Silverado 2500HD crew cab LB LTZ at 60,000 miles. I have 140,000 miles on my truck now. looks like I will be replacing them soon. Never had a problem

These tires went on our F250 Diesel. In less than 3 months we have put aver 7500 miles on them. No funny wear, great ride, no noise. And the size is 35". I would reccomend these to anyone. Mud, Dirt, Rain , Snow and Dry Pavement. Great tires.

loved the KO1's. Had 4 sets, now time to buy new set for my 20" wheels and cant get RWL? That was one of the best features was how good it looked when they were clean. Hope they fix this soon!
