No wonder people are concerned - carbon dioxide spewing from vehicles is the single greatest cause of greenhouse gas emissions.
By measuring your tires' pressure once a month, and maintaining proper tire inflation, you could save two weeks worth of gas a year, the cost of one or two sets of tires over the lifetime of your vehicle, reduce harmful emissions, and increase the safety of your vehicle.
Proper tire care is simple and easy. Measure tire pressure monthly, including the spare, using a good-quality tire pressure gauge.
You can't tell if your tires are properly inflated just by looking at them. If you're not sure how to do it, ask someone to help you.
Remember, a change in temperature can mean a change in tire pressure. Check out betiresmart.ca or vehicles.gc.ca for more tips on being tire smart this winter.
