Can you drive on winter tires in summer? risks, wear and when to change your tires
Driving on winter tires in summer is possible, but it is generally not a good idea. You lose performance, your tires wear out much faster, and your fuel consumption increases. In most cases, it is better to switch to summer or all-season tires once temperatures consistently stay above 7°C.
Why driving on winter tires in summer is a bad idea
Winter tires are designed to perform in cold temperatures, on snow and ice. As soon as temperatures rise, their behavior changes. The rubber becomes too soft, which directly affects safety and durability.
In Canada, where temperature variations are significant, this change in performance is especially noticeable in spring and summer.
1. Longer braking distance on warm pavement
This is one of the most important impacts. On hot asphalt, winter tires lose braking efficiency. Their softer compound and numerous sipes reduce grip during emergency braking.
Using winter tires in summer can increase braking distance by up to 26%. In some cases, this means several extra meters before the vehicle comes to a complete stop. That difference can be critical between stopping safely and getting into a collision.
2. Higher fuel consumption
Winter tires create more rolling resistance in summer. This forces the engine to work harder, which increases fuel consumption.
This difference can represent about 5 to 10% more fuel usage depending on the vehicle and driving conditions.
Over a full season, this can add up to a noticeable cost, especially with current fuel prices.
3. Much faster tire wear
This is often the most convincing argument. Winter tires wear out much faster in summer.
Why? Their rubber is designed to stay flexible below 7°C. Above that temperature, it becomes too soft and wears quickly on hot pavement.
The well-known 7°C rule over 7 consecutive days is a good guideline. When the average temperature stays above this threshold for about a week, it’s time to switch.
Driving in summer with winter tires can significantly reduce their lifespan. You may need to replace them after just one additional season, which cancels out any potential savings.
4. Reduced stability and handling precision
Winter tires are designed to grip snow, not to provide optimal handling on hot or wet pavement.
In practical terms, this results in:
- Less precise steering
- Increased body roll in corners
- A floating sensation at higher speeds
- Reduced water evacuation during heavy rain
On wet roads, the risk of hydroplaning may even increase, since winter tire tread patterns are not optimized for summer conditions.
What is the best tire option for summer?
For most drivers in Canada, two options are available:
- Summer tires: ideal for maximizing performance, safety, and durability in warm conditions
- All-season tires: a practical compromise if you prefer not to change tires twice a year, but less efficient than dedicated tires
At PMCtire, we generally recommend having separate sets of winter and summer tires to maximize safety and get the best long-term value.

Is it illegal to drive on winter tires in summer in Canada?
No, it is not illegal. In some provinces, such as Quebec, winter tires are mandatory from December 1 to March 15, but there is no restriction on using them in summer. However, it is not recommended for safety and performance reasons.
Is it dangerous to drive on winter tires in summer?
It is not automatically dangerous, but the risks are higher. Braking distances increase, stability decreases, and grip is reduced, especially during emergency maneuvers. The risk of tire damage may also increase, particularly if your winter tires are near the end of their lifespan.
When is the best time to change your tires?
As soon as the average temperature stays above 7°C for several consecutive days. In Canada, this typically corresponds to April, depending on the region.
In summary, can you drive on winter tires in summer?
You can drive on winter tires in summer, but it is almost never a good idea. Between reduced performance, accelerated wear, and higher fuel consumption, you end up losing on multiple fronts.
If you want to optimize both your safety and long-term costs, the best choice is to switch to summer or all-season tires as soon as weather conditions allow. It’s a simple decision that makes a real difference on the road, especially given Canada’s varied driving conditions.
