It's just one of those things guy. Depends on the bike, the tire tread, compound, etc. Balancing may have a bit to do with it and sometimes it don't matter how much you balance. the tire just does it. I've tried lossa air, medium air, slime, etc. just delays the cupping sometimes. Sometimes it don't. My old R11GSA use to cup the heck out of the front tire about the time it was time to change the back so it stayed getting sets ha ha ha.. -- Best Regards & Happy Trails Andy Chesley @ 57 and ticking Y2KLR650 @ 4K sMiles 97 R11RA (Amiga) @ 14K Miles So Many Roads, So Little Time http://members.deltech.net/aches/
