Canadians have more
winter tire choices than most drivers around the world. With vast Canadian
landscape, winter driving means different things in the snowy Maritimes, cold
urban roads of Quebec and Ontario, frigid and windy prairies, and BC’s warmer
Lower Mainland and unpredictable mountain roads. That’s why Canadians are
offered a wide range of tire products for winter driving.
According to study from Traffic Injury Research
Foundation (TIRF; www.tirf.ca):
at temperatures just below freezing, stopping distances
for vehicles with winter tires are as much as 30% shorter than for vehicles
with all-season tires (marked M+S/Mud and Snow tires), and
winter tires deliver better traction on an ice
or snow-covered road surface at -30°C vs. all-season tires at 4°C.
The Canadian tire industry and the Tire and Rubber Association of Canada led the creation of the ASTM F-1805 test method and the development of the Three-Peak Mountain Snowflake (3PMS) symbol. Since 1999, the test and the symbol are used throughout the world to identify tires designed for winter driving.
ASTM F-1805 Driving Traction Test and Three-Peak Mountain Snowflake (3PMS) Symbol
Canadian Government recognizes tires carrying 3PMS
symbol as winter tires that meet the safety standards for winter driving. Canadian
federal regulation under Transport Canada mandates all tires manufactured
and marketed to perform in winter conditions must
pass the ASTM
F-1805 Driving Traction Test and carry the 3PMS symbol.
Winter tire testing is innovative, reliable, and
sophisticated, and ASTM F-1805 Driving Traction Test is a performance-based
standard. Only tires with advanced tire designs, treads and rubber compounds designed
for winter conditions are capable to meet and exceed this standard. Only
tires that pass this test may display the 3PMS symbol on their sidewall in
