The tire light came on

Every year, the first cold snap turns on a few thousand tire warning lights across this metro on the same morning.

Short answer

Cold air lowers tire pressure measurably, so a sharp temperature drop commonly triggers the warning light on otherwise healthy tires. Check pressure when the tires are cold, fill to the number on the driver’s door jamb — not the number on the tire — and watch for a tire that keeps losing air, which means a leak and a repair shop.

The facts, in one place

  • Cold snaps trigger warning lights across the metro at once.
  • Correct pressure is on the driver’s door jamb sticker.
  • Check when the tires are cold, before driving far.
  • A tire that repeatedly goes low has a leak — get it repaired.

Why it happens here

Air contracts as it cools, so a thirty or forty degree overnight drop takes a noticeable amount of pressure out of every tire in the parking lot. That is normal physics rather than a failure. Topping them up is a five-minute job at any station with a working air pump.

When it is more than cold

If one tire is the only one low, or it goes low again within a few days, there is a puncture or a bad valve. Driving on a genuinely underinflated tire ruins it and handles badly on ice. Get it looked at rather than topping it up every week.

Questions people actually ask

Should I use the number printed on the tire?

No. That is the maximum for the tire, not the correct pressure for your car. Use the door jamb sticker.

Can a helper change my tire?

Some people will help with a spare in a safe lot. On a road shoulder, call roadside assistance instead — that is not a place to kneel next to traffic.
