Why Winter Tires?Winter tires have an aggressive tread design that provide a bettergrip while throwing off snow and slush, providing more stability whenbraking and better vehicle handling.
The rubber compound of a winter tire is relatively soft. The rubberin an all-season tire starts to lose elasticity and harden attemperatures around -8°C to -10°C, greatly reducing grip. At -15°C,this type of tire will have lost all its elasticity, whereas a wintertire will only harden at around -40°C – it therefore retains itselasticity for much longer.
When purchasing/installing winter tires, remember the following:
Tire inflation
Tread depth check
Regular tread depth checks are important to ensure that your car’stires are safe. Excessive wear can result in a loss of traction,especially on wet and slippery roads. Tires are regular wear items andstaying on top of their condition not only ensures your safety, butalso gives you the opportunity to plan ahead and budget for inevitabletire replacement.
The simple way to measure tread depth is with a tread depth gauge.Tire wear bars are also used on today’s tires as a hands-off visualindication that a tire needs replacement.
“Proper tire inflation pressure and tread depth are critical forgood fuel economy, safety, maximum tire life, and proper handlingperformance,” said racecar driver and Car Care Canada spokespersonKelly Williams.

Winter tire 係雪地行好過四季呔......, 好多加拿大人早就知道, 近年亦好多人都換左. 不過加拿大立法強行一定要裝 Winter tire 係部份人 d 利益問題, 唔係因為市民安全. 只不過借題抓銀. 同 d 環保樹葉紙袋一樣........
