When you depend on a tire pressure monitoring system (TPMS) to let you know when your tires are either over or underinflated, you may have some confusion when your dash warning light seems to always come on when the mornings are cold in Saskatoon. Then, the light goes out a few hours later. We at Dodge City Chrysler Dodge Jeep Ram would like to inform you of one possible reason why this keeps happening.

The air inside of your tires is susceptible to the same effects of cold as the air outside. When the temperatures turn frigid, your tires' air contracts, which temporarily underinflates them. This contraction of air then sends a signal to your TPMS, which illuminates the warning light.

As the temperatures rise during the day, the air then expands, giving your tires the right pressure. However, if the light does not turn off, there may be another issue with your tires that will need professional attention.
