Who should choose winter tires?

Winter tires are essential for drivers who face frequent snowfall, icy roads, or long stretches of cold weather. They’re also the best choice for motorists who want maximum safety, traction, and control in harsh winter conditions. If you live in an area with winter tire regulations (like Quebec or parts of British Columbia), winter tires may be required.

If your region experiences a long, cold winter, switching to winter tires provides the traction, confidence, and peace of mind you need on the road.

When should Winter tires be installed?

Experts recommend installing Winter tires once temperatures consistently fall below 7°C. This is when All-Season tire rubber starts to harden, losing grip on cold pavement.
Switching early helps ensure you’re ready before the first major snowfall.

Can Winter tires be used year-round?

While it’s possible, it’s not recommended. Winter tires wear faster in warm temperatures due to their softer rubber compounds. Using them year-round can reduce tread life and performance. For a single-tire solution, consider All-Weather tires instead.

How do I know if my tires are Winter-rated?

Look for the 3-Peak Mountain Snowflake (3PMSF) symbol on the sidewall — this certification guarantees that the tire has passed winter traction standards.

What can you do to look after your new winter tires?

1. Regularly inspect tire pressure (PSI) and adjust to the manufacturer’s recommended pressure found in your owner’s manual or on the driver’s door jamb. Proper maintenance can lower fuel costs and help protect the environment.

2. Get an annual wheel alignment service. Hitting bumps and potholes gradually throws off alignment, causing uneven wear and increased rolling resistance. We recommend an alignment once a year or if you notice steering pull or tire damage.

3. Switch tires at the correct time. Follow the 7℃ rule — change out winter tires when average temperatures consistently rise above 7℃.

Is the tread different on winter tires?

Yes. Winter tires have a single-directional tread that pushes away snow and ice. They include grooves (sipes) for better grip and handling and have a deeper tread. Tires must have at least 3.5 mm of tread remaining to be considered winter tires.

Will having two sets of tires cost more?

Many people avoid switching tires due to cost concerns. However, according to the Traffic Injury Research Foundation, research suggests that using winter tires is less expensive long-term than using all-season tires. Switching between two sets prolongs the life of each set.

Are winter tires required by law?

British Columbia: From October 1 to March 31, drivers must obey winter tire and chain signage. Mountain/snowflake tires are recommended for cold weather driving, and chains are advised in extreme conditions.

Quebec: Winter tires are mandatory from December 15 to March 15.

Can you replace just two tires?

No. You should replace all four tires. Having four tires with the same tread pattern, material, size, and wear improves handling and control on wet and slippery roads. Mixing tires can compromise vehicle stability and lead to oversteering or understeering. Transport Canada recommends installing snow tires in sets of four, and this is Fountain Tire policy.
