Does anyone know if the Arizona climate affects how much pressure should go into the tires? 32 PSI seems to be the magic number, but that is "cold" tire pressure (according to the FAQ). Has anyone taken note of warm weather changes to this number?

EDIT: Note the new "owner" status to the left. Mmmmmmmm...Grand Prix White...<drool>

GameDev,

I have figured out that driving a bit over one mile to the air pump warms up my tires on a Phoenix afternoon. If I set it to 34/34, I will find the tires at 29-30psi when I check my true cold pressure the next morning.

I've been using 37 in the front and 35 in the rear cold tire inflation pressure. I got my S2K in May and only put air in the tires after the car sits overnight in the garage. Of course with AZ summers, the garage doesn't cool much below 90 degrees by morning. I never checked the hot tire pressures, but assume that it goes up about 6 to 8 psi. I traveled to So Cal at some pretty high speeds during the heat of day and had no tire problems.

I have yet to break the tires loose in (what I consider) spirited driving. I settled on these pressures after searching the site for tire pressures. I was looking for a balance between performance and tire wear. My front tires at 5500 mile look new and the rears look like they'll last another 8 to 10k miles easy. I just read somewhere that somebody else thought 35 front and rear tire pressure was best, based on some real world testing back east.
