I've not had a back tire problem ,but I did experience a front tire bounce so bad I had to park the bike . Mine was a brand new tire, but totally out of balance. We [dealer ] worked it out after a few tries , runs great now. The dealer stated that some tires are more difficult than others to balance, and he has replaced a few new tires that were just plain bad. I've always balanced car tires but this was my first problem with a motorcycle tire. Glad I had a nice bike shop that worked with me to solve the problem. CMS
