15 · Wednesday, November 25, 2009 OAKVILLE BEAVER · www.oakvillebeaver.com Winter tires: it's how we roll in Canada The great Canadian winter is nearly upon us. Drivers from coast-to-coast are either changing over to winter tires, or trying to decide whether winter tires are right for them. To help with this annual decision, Canada's tire makers are giving consumers the facts with a winter tire and driving brochure available free from participating tire retailers and online at the industry's tire education website betiresmart.ca. In recent years, more and more drivers have chosen to invest in winter tires, and with good reason. Recent advances in winter tire technology offer motorists significant advantages, not just on snow or ice, but on cold dry road surfaces as well. Rubber stiffens as temperatures get colder, reducing traction capability. Modern winter tire rubber compounds, however, keep their elasticity even at temperatures as cold as minus 30 degrees Celsius and lower. The result is superior traction and performance in all road conditions during winter. "The idea that winter tires are only for snow or ice covered roads is old-fashioned thinking," says Glenn Maidment, President of the Rubber Association of Canada (RAC), which represents Canada's tire makers. "Drivers should think of winter tires as `cold weather' tires that offer superior traction, braking and cornering in every winter driving condition, including dry surfaces. The surface grip advantage offered by winter tires becomes evident when temperatures fall below seven degrees Celsius. When you can see your breath, its time for winter tires." Since the late 1970s, all-season tires have been a popular choice for Canadian drivers. Even though all-season tires can provide safe all-weather performance, drivers need to know that winter tires are more efficient once the temperature starts to fall. Winter tires offer up to 50 per cent more winter traction than all-seasons. Canada's tire makers also advise motorists to use winter tires on all wheel positions. Using winter tires on the front or rear axle positions only can create a serious traction imbalance that can lead to a loss of control. When shopping for winter tires, motorists should look for the "three peak mountain snowflake" on the sidewall. Only tires stamped with this distinctive symbol meet or exceed specific snow traction requirements established by the tire industry. Another key to safe winter driving is proper tire inflation, which is more challenging to maintain in winter. Every five degree Celsius decrease in temperature results in a loss of about one psi in air pressure. Tire under-inflation is a serious threat to vehicle safety. Under-inflated tires have a smaller footprint, which weakens their grip. The result is diminished braking and handling capabilities, not to mention significantly higher fuel bills due to increased rolling resistance. Drivers should use a tire gauge to measure their air pressures monthly to ensure their tires are always inflated to the vehicle manufacturer's recommendation. Visual checks are not an accurate way to measure inflation. Winter tire consumers should also remember that excessive tread wear can diminish traction. Tread depth should always be checked at the start of the winter driving season. Drivers who are unsure if their tires are overly worn should consult a tire professional.
