Tire Pressure Monitoring System

If your TPMS (tire pressure monitoring system) warning light goes on when the weather drops/rises, it does not always mean you have a leak. 

Tire pressure can decrease about 1 PSI (pound per square inch) for every 10 degrees the temperature drops. It's not that more air is escaping your tires, but rather the air inside the tire condenses, taking up less space when it's cold. 

Tires also lose about 1 PSI per month just from seepage of air around the edge of the rim and through the tread itself.

These two factors combined can cause the air pressure in a tire to go 25 percent below the recommended fill pressure. This is what triggers the sensing transmitters inside your tires to illuminate your TPMS dash light. Whenever your TPMS light comes on, have your air checked and bring your tires up to the proper pressure. It is still possible that you may have a leak in your tire or rim and it is recommended to have your tires checked for leaks, even when just adjusting your tire pressure for the cooler temperatures.
