When to change to winter tires in Ontario

Icy roads. Slippery slush. Winter is on its way. Not sure if you should spring for winter tires this year? The answer is yes. According to Ontario’s Ministry of Transportation, all-season tires are not suitable for driving in the snow belt and northern regions of southern Ontario and the north.

Why winter tires make a difference in Ontario

All-season tires are designed to handle a wide range of road conditions and are generally adequate for moderate climates. However, in Ontario, where temperatures can drop well below freezing, and roads often become icy or snow-covered, winter tires offer a significant advantage. Their specialized rubber compound stays soft and flexible in sub-zero temperatures, helping maintain optimal grip and traction when it's most needed.

Here are the key benefits of choosing winter tires in cold weather:

• Improved braking: Winter tires can shorten stopping distances on cold, wet, icy, and snow-covered roads when compared to all-season tires.
• Enhanced traction: Deep grooves and intricate tread patterns (sipes) help winter tires bite into snow and ice, improving grip and reducing the chance of slipping.
• Better handling: The flexibility of winter tires at low temperatures enables more responsive steering and control, making it easier to navigate winter conditions safely.
• Increased safety in the cold: As temperatures drop below 7°C, all-season tires begin to lose their elasticity and effectiveness. Winter tires are specifically engineered to maintain performance in these colder conditions.

The 7-for-7 rule for winter tires

Ontario's unpredictable weather can make it challenging to decide the right time for your tire changeover. To simplify this, you can follow the "7-for-7 rule." This guideline recommends switching to winter tires once the temperature has been consistently below 7°C for seven consecutive days.

This rule is effective because it ensures you are prepared before the first major snowfall or unexpected freeze. Waiting too long can put you at risk, while switching too early can cause premature wear on your winter tires. By monitoring the daily forecast and applying the 7-for-7 rule, you can plan your tire swap at the ideal time.
