I have about 24,000 miles on them and they have well over 50% tread left. They're still quiet on the road and they still have plenty of grip off road. I have zero complaints about them. I would buy them again. They weren't cheap in 17" though. I paid about $ 1700 for five of them, which made them the same price as the KM2's.
I'm probably gonna run 38x14.50 KM2's on my next set. In the Goodyears, I would have to jump up to a 40 to get the extra width I want. I kind of want something for a comparison also.
I just sucks that I drive so much. I really hate seeing tires melt away since they cost so much. The 38's are gonna cost me about $2200 or so. Hopefully I can get another year and 20K out of them.
I really need to start riding my motorcycle more.
