If you want to be very specific in terms of tire wear and contact patch... do a chalk test. Take a piece of chalk and mark from the sidewall and over the shoulder of the tread in four spots around the tire. Go out and hit some corners after your tires have warmed up. If there is chalk on the tread, your too high, if the wear mark is right on the shoulder, your just right. If the wear pattern goes into the side wall your too soft.

Once you get the chalk test right on, check your pressures, these pressures are hot pressures and back off 3-4lbs for cold pressures. Guages have inconsistancies so you almost need to "calibrate" your guage, based on this test.

With my guage I run 24 cold front, 33 cold rear... 205's front 245's back
