Gonna have to replace my rear Avon before the trip to Fontana in June. The storm on the front is holding up well and has a lot of life left in it. I liked the Avon but it seemed to wear out reletively quick, which is my only complaint, and thought I'd try something known to have a little more longevity like a Metz. Anybody know a reason why you can't or shouldn't use another tire as long as it's the proper size and a construction?
