So not sure how many people here are into big trucks with mud tires, but my BF Goodrich KM2's are getting pretty worn so I'm saving to get my next set. Right now my first choice is a set of Nitto Trail Grapplers, but I recently came across the Cooper STT and they are about the same price and look pretty good. Anybody have any experience with either of these for a comparison? I would love to get another set of KM2's but they are around $500 more for the set.
