Tire pressure & colder weather
Live in Upstate SC and we do get some colder weather and I have noticed the last couple of times I have driven the Vette on an early am that I am showing low tire pressure (25lbs) till tires warm up and then it creeps up to 27lbs or so
First what should my tire pressure be, should it be around 32lbs(Michelin )
Should I put more air in the tires in the winter
Car is not a daily driver so it sits a lot

There are lots of threads on this forum about this.
Standard is: 30 lbs COLD pressure.
That is, the tire pressure when the car has not been driven for at least a few hours, or even better, overnight.

the recommended pressure on your door label is 30 lbs. note: in your garage, it's probably no less than 40-50 degrees (or more). park your car at the office in 30 degree weather and you could be 1-3 lbs. lower. also remember that the most accurate check is by tire gauge, not necessarily your DIC panel.

When the temperature outside is swinging drastically, I try to keep it between 29 - 31 psi. But like others said above, it will vary based on car temp, and there is a big difference in the garage and outside. Mine is a DD and it sees all extremes, but I am seeing pretty consistant tire tread wear.
NOTE - for better traction, watch the DIC, and don't romp it (especially with GY tires) until the tire pressures increase 2 - 3 psi. Time will vary, depending on how cold it is outside, and how sunny it is.

I agree.

Air molecules slow-down & contract in cold temps, so yes more tire pressure's required in cold weather. Cold tire pressure's a bit of trial & error, as others have said probably around 2-3#s.
I live in WI, colder temps are a fact of life. I must check tire pressures more often as soon as median temps fall below 50* F.

The rule of thumb is for every 10 degrees of temperature the tire pressure will move 1lb. So if you set it at 30psi at 30 degrees cold and later in the day the temps rise to 50 degrees and you didn't use the car they should be about 32psi at the 50 degree mark, and visa-versa. Tire pressure is very temperature dependent.

Here is my $0.02 on this issue. Not much of my driving is done on cold tires. I like to see 34 - 35 psi when the tires are warmed up, so I start with the pressure that will give me the desired results. Normally that is 30 psi summer and 32 psi front and 33 psi rear in the winter. I've gone thru several sets of tires and they wear even so this works for me and my driving style.

Northern South Carolina must be brutal this time of year....down to 40 degree's and everything! It's going to be a high of 15 here on Friday!
Tommy you know I'm giving you "razz-berries" because mine sits under a cover with a tender starting two weeks ago...and will be like that until April.
Wish I could participate in this thread without having such a red-a$$ because of where I live.....

Hey I was in SOUTHERN IL 2 weeks ago and it hit 13 one am in the deer stand, NO WONDER ya'll move down here
Can not imagine putting my boat up in the winter much less MY VETTE
By the way can anyone recommend a decent digital tire pressure gauge. I have a several tire gauges but guess I need to get a digital one but would like to get one that really works and will last

I'm at 27 cold and still not getting the whole contact patch to touch, might be the Z06 style rims, but 30 cold and the outside 2 inches on each side don't touch the road. I hate to see the center of the tire wear out first telling me too much air pressure

I adjust mine for the average temp for the month in my area....so upstate sc is 50 ish so I adjust for 32ps1 in front and 31psi in rear for that at 50 degrees. I have found that pressure works best for even tire wear for my driving in the Vette
