Holy carp, that low?First thing to do is check your tire pressures. Depending on the tires your fronts should be 26psi and the rears 32psi.
I've been running my tires higher. I noticed uneven wear and lowered the pressure front and rear substantially recently, but still north of that in the front by a bit.
My tires have a larger diameter radius by 3% front, and 7% rear. I don't understand how that would influence the pressures I run in them, if at all. Any general advice?
