Been trying to find a set of used 37 or 38-inch tires for a while now without any luck. I have a run coming up in 2 weeks and it looks like I'll have to buy a set new. Where is the best place to buy tires in the Detroit area (or within an hour)? Probally going with SS TSL's or similar. I can't resist crossing the border to buy since our dollar is like equal now.
