Anyone experince cupping on the front tire. I have 2009 F with 5000 miles and noticed the front tire is cupped. The tire still has the OEM weights but I noticed there is 1.75 oz of weight on the front tired. That seems to be a lot of weight for a motorcycle tired. I took the factory weights off and put Dyna Beads in the front and rear to see if tha would improve things but the front tire cupped too deep already and suspect i will have to buy a new fron tire. I should of been able to get 20K miles out of the front. Suspect HD did not do a very good job of balancing the tire.
