Do different tires call for different psi?
IRC, DR2, Pilot Street Radials, Pilot Power, etc.
I've been experimenting with pressure lately. I have a DR2 up front and a Street Radial in the rear. So far, I ""think"" I like F30/R34 the most. It's not too jarring over bumps and the feedback is pretty good.
EDIT: On the other hand.....1 or 2 psi won't really matter. I have 3 gauges. All 3 gauges read a different PSI!!!! One is off by 4psi
Only if there's a way to calibrate them. Sigh....
