Every year, winter arrives on December 21st, according to the calendar. Less predictably, lower winter temperatures can arrive at any time during the transition from fall to winter weather (last week in Burnaby / Metro Vancouver). If you are looking for winter tires, Westminster Toyota is excited to announce our participation in the manufacture rebate program on top of our competitive pricing.

Allseason tires continue to provide safe allweather performance, but may not always be suitable for severe snow conditions. Allseason tires do not have cold weather rubber compounds, channelling tread patterns, the large number of tread sipes (tiny slits in the tread blocks) for wet surface control, and the open tread block pattern for deep snow traction that winter tires feature. The lack of a formal "snow" designation on the tire has further fuelled the misconception that "all-season" tires also mean "winter" tires.
On dry pavement, the performance of an allseason tire steadily declines as the temperature gets colder. The crossover point is about 7 degrees Celsius. Colder than that, a winter tire outperforms an allseason tire. Winter tire performance sharply improves as temperatures fall from 7 degrees to minus 30 degrees Celsius, while the allseason tire approaches the "not recommended" status.
Winter tires typically feature a unidirectional tread design. The unidirectional, V-groove tires move slush and water out of the way better than any other tread design. The more open the tread design, the better the tire will perform against accumulated snow. The larger the tread blocs, the better the handling, steering response, and transient response. The more sipes (tiny slits in the tread blocks), the better the tire will work on wet pavement, which is different than anti-hydroplaning.
