Should I inflate my tires in the winter?

Temperatures have dropped in Kamloops with our current cold snap, but will thaw out by next week. Changes in temperature mean a change in tire pressure. As it gets colder, you may notice your TPMS light come on, but this doesn’t necessarily mean your tires are leaking. While tire pressure should come back up to normal after the cold spell with a rise in temperature, driving on low tire pressure is never recommended, even in the interim.

Check your tire pressure with an accurate tire pressure gauge, preferably before they’ve been driven on and they warm up. The manufacturer’s recommended tire pressure is on the door placard. Low tire pressure can lead to increased stopping time and easier skidding on wet roads. They lower gas mileage leading to poor fuel economy and decrease tire lifespan. Underinflation makes them more vulnerable to damage.

If your tire pressure light stays on after inflation, you may need to reset it. Drive the vehicle for about ten minutes, then park and restart the car. Your TPMS light should now be off. If not, turn the key on to the auxiliary position without starting the car and press the reset button until it blinks three times. Start the car to allow it to reset. You may have to check your manual to locate the reset button. If that doesn’t work, bring your vehicle in to our service centre and one of our auto techs will check your tire pressure again and reset the TPMS light for you.

Check your tire pressure often, as your tires can lose one pound of pressure with every ten degree drop in temperature. Driving on underinflated tires can lead to premature wear, tread separation and blowouts.
