For someone who knows more about the new ultras than me. have 10K on my 09 now and I noticed a rumble about 3 or 4 thousand miles ago when cornering. took the front tire off to change the front springs the other day and found the problem. The tire is severely chopped. On a car this is the sort of thing that usually comes from bad struts or a bad alignment, but where is it coming from on a new bike?

 

I have an 09 Ultra as well and the front tire is cupped and worn almost to the wear marks. Showed it to my Service Manager and he said he would call Harley and talk to them about it. I only have 7K on it and keep the pressure at 36 psi. Hopefully they'll come across with a replacement. Some of the guys online here have been getting theirs replaced. Good luck.

 

Do a search for "Dunlop 407f 408f" lots of info

 

the service tec at my dealer said raise the pressure. 38+

i set mine at 40 i figured it could not hurt the tire is already toast
