(NC) — When the snow flies, Canadian drivers have to be prepared. Temperature swings, which are common across Canada during the fall and winter months, can result in significant changes in tire pressure. For example, did you know that for every 5oC drop in temperature, tire pressure drops by one pound per square inch (psi)? So if the temperature were to drop to -15oC, tires could lose three psi of tire pressure. For some tires that means a 10 per cent loss in inflation.
By maintaining proper tire inflation, consumers can save money at the pumps and reduce harmful emissions. Most importantly, they can increase the safety and performance of their vehicles by ensuring that their tires are being used within the correct operating specifications and conditions for the vehicle. As well, because properly inflated tires will last longer, you could save the cost of one or two sets of tires over the life of your vehicle.
According to the Tire and Rubber Association of Canada, even though many drivers use all-season tires because they do provide safe all-weather performance, winter tires are actually more efficient once the mercury starts to dip. The association says modern winter tires offer up to 50 per cent or more traction than all-season tires.
If fuel efficiency and safe winter driving are important to you, there are some very helpful tips and tools on the Natural Resources Canada website at vehicles.gc.ca such as the EnerGuide Label for Vehicles and the annual Fuel Consumption Guide.
