So the cold tire pressure is suppose to be at 30 psi for my car. Well it’s 5F out today and one of the tires went down to 24 psi. Naturally that exciting “low tire pressure” light came on. I’m gonna inflate it a bit later today, but should I put it to 30 psi, or maybe a high 20? I know once the temp goes up, the air expands and improves the psi, so I’m unsure what to fill it up to.
