Why Your TPMS Light Comes On When Temperatures Drop

TPMS Lights Don't Like the Cold

Have you ever noticed your tire pressure light glowing on those first cool mornings in Gainesville? Don’t worry—you’re not alone. As North Texas heads into fall and winter, cooler temperatures can cause changes in your tire pressure that make your TPMS (Tire Pressure Monitoring System) light turn on.


Here’s what you need to know:

Why Cold Weather Affects Tire Pressure

  • Air contracts when it gets cold. For every 10°F drop in temperature, your tires can lose about 1–2 PSI (pounds per square inch).

  • Even healthy tires are affected. This means you might start your car on a chilly morning and see that TPMS warning, even if nothing is wrong with your tires.

  • Low pressure = unsafe driving. Underinflated tires wear faster, reduce fuel efficiency, and increase the risk of a blowout.

What To Do If Your TPMS Light Comes On

  1. Check your tires with a gauge. Don’t rely only on the light—use a tire pressure gauge to confirm the actual PSI.

  2. Fill to manufacturer’s specs. You’ll find the recommended pressure inside your driver’s side door or in your owner’s manual.

  3. Don’t ignore it. Driving with low tire pressure can damage your tires and affect your safety.
