I'm running STT's 265/70/16, they are great. No problems, good traction on the black top & lot's in the mud/dirt. They cost more than the rest over here but I'm happy to pay

The main reason I got the Coopers over another brand was the Sypes in the tread, from what I understand they help when on the black top with traction in the wet. At least that's what I was told & I've had no reason to think otherwise. The other muddies I was looking at didn't have that feature & as I have kids in the KJ I want a good reylable tyre in all conditions.
