The picture below is the front tire on a 2009 FLHTCUSE4. I have around 11,500 miles on this bike. I am curious to know how many miles should I get out of this tire. As you can see the tire is cupping in the middle which gives a bumpy ride, and there is not a lot of tread in the middle of the tire. My previous experience on other Harley's, I have been able to get around 17 to 18,000 miles on the front tire before replacing. I had read somewhere that these new tires on the 09's that a special rubber was used and that the tire life should be extended from what the normal life of a tire was. Well I am not impressed with the tire life that I have seen up to now. I am curious to hear what others have seen on their 09's on the tire life of their Ultra's. Maybe I got a bad tire from the start. Anyway what causes the cupping of this tire and shouldn't the tread have lasted longer than 11,500. Your comments welcomed.
