Okay, just got back from the dealership and they filled all 4 of my tires up to 38psi.the side of the door calls for 32psi and when asked, dealer stated that colder temp is coming and 38 is the right psi for winter time.
well, i just noticed today while driving on the freeway, the PSI went up to 41psi... I think it's too high.
am I right? should i adjust it lower? or am I just totally wrong and dealer is right.
too many questions, too little time.
Proper tire pressure for 06 M35
Re: Proper tire pressure for 06 M35 (eggyacid)
33-35 is what I use when cold sitting in the garage. Mine go upto 36 here in Florida when driving.

Re: Proper tire pressure for 06 M35 (eggyacid)
I recommend a cold pressure ("cold" means "cold" ... overnight, in a garage ideally, not even letting the sun hit it ) of 36 psi and then adjusting up or down (only a bit) to get the right wear on the tires across the tread.
For very high speed driving (like if you were on the Autobahn in Europe), then you have to bump it up between 3 to 7 psi higher than usual ... for that trip. This is to avoid too much sidewall flex at high speeds (can damage tires and lead to premature failure ... ala Ford/Firestone where the pressure could get too low - even for US highway speeds - if the owners were careless).
BTW, a tire that reaches 41 psi during normal driving is not a problem. As long as the cold inflation pressure does not exceed the maximum marked on the sidewall (usually 51 psi, or 44 psi on older tires), then you are perfectly fine!
