So how worn is worn? I cant understand how some of you get 10K or more from a rear tire. Do you run it until the threads are close to showing,is there still a small amount of tread in the middle? I put just over 3500 miles on new Metz Me88's on a 01 E Glide and the rear is squared off from freeway runnin and bald on the contact patch. The tire was rebranded by Metz over the O/E sidewall spec with the max pressure or 50psi IIRC so thats what I run. I thought is was bad doin a Pirelli N/D every oil change on the Dyna but 3500 miles can be for real. Shinko's, Michelins? any advice? The Dunlops were better but not by much.
