On my 3rd Set

Love these tires. I got 40,000 miles on my last set after beating them off road and on. I drive a Jeep JKU 2017 with a 3.5 Flex Suspension. I've pushed these tires through Mud, Rocks Obstacles and they always perform exceptional. Even had a 2 inch nails try to puncture these tires. I've never had a flat.

Good even in the rain!

Great off road and in the snow as expected. But what most people don't know is that All Terrain and Mud Terrain are often terrible in the rain but the k02 disappoint. 3 sets so far on a two Tacomas and one 4x4 Sprinter.

Great truck camping tires!

I totally agree with the Cattle Guy. I've been running these tires on my 1 ton F350 4x4 with a 4000lb Atctic Fox camper on the back and they have been great in all weather and terrain conditions! But then I knew they would as I've been a fan of these tires for many years and continue to be impressed by them.
