I was looking around for the Firestone t-831's and the local dealers say that they are discontinued. They look like a great tire for the deuce and will keep the engine and breaking load down (11/20 size). Does anyone know where to find them, I like my michilin xl's but down the road when they wear out I'll need some options. The side wall cracking on the michilins is ticking me off and I haven't come accross any that don't crack. I'm not having any luck finding any newer production rubber, which is the difference with cracking and plyability.
