My 15 tundra came with KO's stock and they are great tires, 37xxx miles and probably have 15xxx more in them. I've ran the durratracs on my 06 jeep unlimited and they were Great tires. I offroaded the crap out of them, lots of rock crawling in VA and PA. They also did great in rain and snow. So they are on my list of replacement tires when the time comes.
