My tire pressure ( all four wheels) is about ten pounds down 22-23 psi in the morning . After about fifteen minutes if driving the pressure is back to 32 all around. My question is; should I add pressure for the winter months or just leave them alone ? I also confirm the computer read out with a tire gage. The tires are new (2 month old).

 

that does seem a bit extreme for the mild climate that VA has. i am farther north and it gets colder up here and mine only varies about 4 psi. cold i see about 28 psi and warm it is at 31-32 psi all 4. i would look into it a bit more. otherwise find a nitrogen fill station. nitrogen doesn't expand or contract like air does....

 

I'm in FL so I don't have the issue, but that does seem a bit extreme. If you do find a nitrogen station, you should be good to go. You still have the GYs on it right? or Nittos?


Sorry to threadjack, but I dyno'ed my Z06 yesterday. 476/448 K&N, no tune.
