I live in Calgary. When exactly should I make the switch?

  • When temperatures rise above 7 degrees Celsius, winter tires lose their grip advantage over all-season and summer tires.
  • According to Environment Canada, the average April temperature in Calgary is about 5°C. This jumps to roughly 10°C in May.
  • This means that the optimal time to change over from your winter tires in Calgary usually falls between the months of April and May.
  • Please check the weather forecast and consider the pros and cons of making the winter-to-summer tire switch earlier or later.

Why don’t I just drive on winter tires in the summer?

  • Winter tires are designed to work best in the cold and are less effective at dissipating heat.
  • Risk of overinflating and blowouts are much higher.
  • The rubber compound is much more flexible, which often results in a loss of control, especially when you make sudden turns.
  • Since the rubber compound is softer, this creates more rolling resistance and uses more gas.
  • When you drive on winter tires in summer, you reduce their lifespan by roughly 60%, as opposed to if they were only used in winter conditions.
  • Tire technology has come a long way, but winter tires are still much noisier than summer or all‑season tires.
