i have a f3 need to know stock tire psi or what u people have it set at thank u

 

You're in the wrong section. This is F1, not F3. Good luck.

 

got you moved to the F3 section now, might be a little better for ya.

 

42 psi at the rear & 36 at the front. check the site out for this topic as a lot of people run different rates depending on their tyres & riding style.(some tyre companies have their own recommendations as well) Slightly lower pressure means that there is more of a contact patch & so they warm up at little faster. If I'm going for a quick blat, I run mine down a couple psi. But if I'm lucky enough to be going on a week-end ride at a reasonable distance, I run them at the recommended.
