Hey guys,

Today was finally a cold morning in the Bay Area. Once, I started my car. I've notice both front tires dropped down to 30PSI, and the rear were 33PSI.

I got warnings for the front 2 tires. However, once I got to work, the front tires went back up to 33PSI, and the rear 35PSI. I'm assuming this is normal for the car to warmup?

But, I went to the gas station and filled all tires to ~38PSI.

Is that good pressure to run all around?

Yup! You want your cold tire pressure (aka pressure before driving) to be 36 psi.

Okay cool. I just checked again, after letting the car sit for an hour. It reads 36 PSI.

I run a larger tire since i have 19" wheels

275/30/19--(summer time PSI 38)(winter time PSI 40)
245/35/19(summer time PSI 36)(winter itme PS 38)


but note!! your tires should be at 36psi cold!!

On the driver side door on the side, there should be a sticker showing the standard PSI for each tire.

At what temperature is considered "cold"?

"Cold" temperature is just the ambient temperature for that day. Usually temperatures don't change enough between days to have an extreme effect on the tire pressure, so checking your pressure at ambient temperature once in a while is fine.

I put 36 PSI front, and 38 PSI rear (cold)
