I don't think so as everyone knows it when tires are cold that is when to check them.
Good for you. I can only count one or two times when a shop in Illinois has tried to mention or compensate for the difference. |
Whoops, duplicate post.

Mine are at 28 cold and as they warm up im right at 30.
What I did notice though is I have less traction when the rears are over 32.. The dealer inflated to 32 at my last oil change. When the car got warm they were up around 35 and noticed a difference in both firmness of the ride and less grip in the rear under hard accelleration. So I felt anyway and changed them back to what they were. |
exactly how cold is cold? :toetap:
on the few occasions I have been able to drive my car in winter the tire pressure has been close to the tripping point for low pressure warning, the outside temp was about 10F, I think it may have even been at 0 or possibly a little below, driving the car for awhile brings the pressure up to 30 on the other hand, right now the tire is at 30psi cold, but then it is 75 in March right now (normally we'd be lucky to be above freezing) |

:iagree: I believe the over pressure or under pressure message occurs at 20% difference from 30 psi. At 35 cold you're only one pound away from getting a high pressure message, which will certainly happen once the tires warm up.
From the service manual: When the TPM system detects pressure above 42 psi the HIGH TIRE PRESSURE warning message is displayed When the TPM system detects pressure between 5 and 25 psi the LOW TIRE PRESSURE warning message is displayed When the TPM system detects pressure below 5 psi the FLAT TIRE warning message is displayed. |

I don't think this is true. I used 38 PSI as a starting pressure before, testing tire / pressure combinations at the track, and I never had a warning due to tire pressure.

32 front and 30 rear for me...Seems to get the best wear for me.

31 cold all year all around.

For those running 30psi, is that regardless of tire brand? I just replaced the GY's with Michelin PS2 ZP's and the tire shop pumped 'em up to 35. Still run 30psi?
