When we get hit with temperature swing day of 40-50°F, your tire pressures can vary as much as 5 PSI with the vehicle at rest. Then, as you drive the vehicle, the tires heat up and it can magnify the difference. Generally, a drop of 25% in tire pressure will illuminate the TPMS light. Running over a nail or screw, corroded aluminum wheels, and tire blow outs also affect your tire pressures. All can lead to your TPMS light illuminating.
