    I have an 03 456M GT that came shod with 17" Bridgestone Expedia S-01 tires. The recommended cold tire pressures per the car's placard are 31 lbs. in the front and 35 lbs. in the rear. I am changing the setup to 19" Pirelli PZero Rossos mounted on 19" HRE wheels. Can someone help me with recommended cold tire pressures for this new setup? Thanks.

    A general rule of thumb is to never go below 10psi/1000lb car weight. The way a racer determines pressure is by having even tire tempurature over the tread for the alignment setting he is using and the way he is driving.
