Tire pressure question

Tire pressure question
I have an '04 RX-8 with a 6 speed, 225/45/18 tires. For everyday driving, what PSI do you keep your tires inflated to? The owner's manual says 32.
Your thoughts?

Yep, I just cold inflation plussed mine up a bit in our now cooler weather. 32 psi for daily driver.
Higher than recommended air pressure gives a bit better gas mileage, but promotes uneven center-tread wear. Dangerous if very high - blowouts.
Lower then recommended promotes uneven edge-tread wear and is dangerous (potential tire unseating if very low).
28 psi is a bit low.
Remember to always check air pressure when tires are relatively cold (not run for a few hours) and in the ambient driving environment.
