Why Is Your Tire Pressure Monitoring Light on in Lower Mainland, BC?

May 25,2022

Your tire pressure monitoring system (TPMS) can warn you if you are experiencing a leak that could eventually leave you with a flat. Sometimes, however, you may see the alert (an exclamation point inside a horseshoe shape) even though you don't have a puncture. It is always safe to visit a service centre if you are not sure what's causing the warning, but it might be natural air loss.  Air Loss Over Time Tire pressure decreases at a rate of about 1 PSI per month, so you may need to add air occasionally to counteract this natural loss. If you do not, it could eventually trigger the TPMS warning.  Temperature Changes Pressure can also decrease by 1 psi for every 5 degrees C of temperature drop. Cold weather can cause the warning icon to illuminate. You may need to add air when the seasons change.  If you are concerned about your tires, contact our service centre to schedule an appointment.
