Weather Whys: Tire pressure and cold air
It's a pain on the coldest morning's of winter - the dreaed low tire pressure light. It always seems to come on when the coldest air of the season has arrived forcing you to get out of your car to check if you have a flat tire and then finding an air compressor at a gas station that actually works.
It's normal year round for your tires to lose about 1 PSI every month but during extreme temperature drops you lose about 1 PSI for every 10° drop in temps. So going from 40s to near 0° would mean a loss of 4 PSI.
