I just put on a new set of 18 inch wheels with the Pirelli p zero nero M&S
the tires were sent to by from tirerack and had a psi of 39 ???
I lowered the pressure to 35 on all four tires. Should i lower to 32 ? 33 ?

Thanks,

I just ordered a set of A-Spec wheels off ebay and was wondering what tire pressure would be recommended with the new tire/wheel size. Got my answer when I opened the box. There was a sticker included indicating 39PSI cold tire pressure recommended. I figured it would be higher than 17s; Tirerack seems to know what they are doing. Max pressure according to Tirerack is 50 PSI, so 39 is within spec.

I too ordered A-Spec wheels, but from the dealer. Mine also came with the stickers. Although, mine stated 39psi front and 36 psi rear. I have the Mich PS2 tires, don't know if that would matter though. Wouldn't think so. Good Luck!

This is correct. I didn't see the 36psi number for the rears until I took the sticker out of the package.
