The Tire Pressure Light Came On

Does the tire pressure warning light keep coming on during winter?

There is a good chance it is not a malfunction. If it is cold outside, that is probably the cause. If your car has a Tire Pressure Monitoring System (TPMS), it monitors your tires for punctures and pressure losses. If the tire pressure drops below the TPMS minimum, it will emit a warning.

The problem with winter is the changing climate causes pressures to drop. Using the formula, PV/T= P2V2/T2, you’ll find tires lose about one psi for every ten degrees.

So if your vehicle’s TPMS system emits a warning, refill your tires and then reset the system. There should be directions to reset your system in your owner’s manual.
