not sure, they're pumped pretty high. I'm going to get a guage today for shraders. I'm going to show my noobness when I tell you I go by feel. I think I did run slightly less psi on my velociraptors, but the tread size/depth/pattern on these bonts is way timid compared to the old tires on the old bike. Can you give me some info on proper psi for loose conditions?
Thanks, again.
