Snow Tire Selection Guide

With temperatures well below freezing and heavy snowfall through the winter, Ottawa drivers need snow tires that suit their vehicle and the way they drive.

Understanding Snow Tire Classifications

Snow tires are specifically designed for winter conditions and are marked with specific symbols and classifications. Look for the mountain/snowflake symbol (3PMSF - Three Peak Mountain Snow Flake) which indicates the tire meets severe snow service requirements. These tires provide superior traction in snow, ice, and cold weather conditions compared to all-season tires.

Key Features to Look For

When selecting snow tires, consider these essential features:

• Deep Tread Depth: Deeper tread grips better in snow; Transport Canada advises not to use tires worn close to 4 mm (5/32") on snow-covered roads
• Aggressive Tread Pattern: Wide grooves and sipes for snow evacuation
• Soft Rubber Compound: Remains flexible in cold temperatures
• Studdable Design: Option for stud installation if needed
• 3PMSF Certification: Meets severe snow service standards

Tire Size Considerations

For optimal winter performance, consider using slightly narrower snow tires than your summer tires. Narrower tires provide better traction by cutting through snow to reach the road surface underneath. A common recommendation is to go one size narrower (10 mm less width) for winter tires. However, always consult with a tire professional to ensure proper fitment and clearance.

Performance vs. Studless vs. Studded

Snow tires come in three main categories:

• Performance Winter: Better dry road handling, good snow traction
• Studless Winter: Excellent snow and ice traction, no studs required
• Studded Winter: Maximum ice traction, but restricted use in some areas

For Ottawa's mixed winter conditions, studless winter tires typically offer the best balance of performance, safety, and convenience.

Brand and Model Selection

Well-known winter tire lines include Bridgestone Blizzak, Michelin X-Ice, Continental WinterContact and Nokian Hakkapeliitta. Each brand offers different models optimized for specific conditions. Consider your driving habits, vehicle type, and typical winter routes when selecting a specific model.

All-Wheel Drive vs. Two-Wheel Drive

While all-wheel drive vehicles benefit from snow tires, they're even more critical for two-wheel drive vehicles. AWD helps with acceleration and stability, but snow tires are essential for braking and cornering in winter conditions. Transport Canada recommends installing winter tires in sets of four, with the same size, load index and speed rating on every wheel, and not mixing tires with different tread patterns or construction.

Load Index and Speed Rating

Ensure your snow tires meet or exceed your vehicle's load index requirements. Speed ratings for winter tires are typically lower than summer tires, which is acceptable since winter driving should be done at reduced speeds. A lower speed rating often indicates a softer compound that performs better in cold conditions.

Installation and Mounting

Snow tires need to be mounted and balanced properly. Consider having them mounted on their own set of wheels: each seasonal change is then a simpler, less expensive on-rim swap instead of an off-rim change, and your summer wheels are protected from winter road conditions.

Storage and Maintenance

Proper storage of your summer tires during winter months is important for their longevity. Store them in a cool, dry place away from direct sunlight. When storing snow tires during summer, clean them thoroughly and store them in tire bags to protect them from UV damage and ozone exposure. See our tire storage guide for more.

Cost Considerations

Snow tires are an extra cost, but they add a lot of safety, and because each set is only used for part of the year, they extend the life of your summer tires. Many insurance companies offer discounts for vehicles equipped with winter tires.

Legal Requirements in Ontario

Ontario doesn't require snow tires, but they're strongly recommended for winter driving. Ask your insurance provider whether you qualify for a winter tire discount.
