I had to get some new tires as my old ones were rotting. A sad fact since they had plenty of tread left. On one rear tire the tread was seperating. I got the best of the brand Futura or somethnig like that. Trac A Temp A Tread wear 400. Anyone ever heard of these or have them? I realize it is to late now since I have them already, but it was necessary since the tread was peeling off the back. Thanks...
