I have been running MTR's for a few years now, and love them. I want to go slightly larger, 35-37", and want to go to a 17" rim size. Why is it that Goodyear wants like, 140 more dollars for a 17" wheel size? If you HAD to think of pure material, it is less! With Swampers, and a few others, it add anywhere from 5-20 dollars, at most. BFG is another one that has a huge jump in pricing. The guys at Goodyear in Monroe (Taylor... :; ) don't know why, either.
