Re: Cupping on Bridgestone BT014
I've had cupping issues too before I kept 42 psi in both tires, and have seen lots more on other bikes.
However, I've never seen any on tires that were kept at max tire pressure (42 psi on most, me-thinks). On the track, you won't want this much obviously, but on the street (unless you ride a place like Polomar al the time) 33 or 34 is way low IMHO.
Personally, I don't think it has anything to do with the brand. I've run Bridgestones on 3 different bikes and I love em.
