It's the rear that's cupping. I use the term "cupping" for lack of a better term. At every tread sipe (groove) the front of the tread block is worn front to back where it turns up a lip on the very back edge of the block at the next groove. I think it has something to do with throttle application at the soft compound lean angle.
Front is fine, no cupping at all, just an inch and a half of the sides starting from about 1/4" from the edges up toward the center are almost wore out.
We have a lot of rough "chip 'n seal" roads around here, good grip but rough on tires. Well, good grip except where the "seal" has oozed up through the "chip", those sections can be very greasy.
Next time I get the Busa out I'll take some pictures of the tire wear patterns, post 'em, and see what everyone thinks is going on.![]()
Pics would help
