What’s the Difference Between Winter and Mud & Snow Tires?

Given the name, ‘mud and snow tires,’ it would be understandable if you thought M+S tires were suited to winter conditions. And yet M+S tires are hardly winter tires. What’s the difference between true winter tires and mud & snow tires?

It’s not just the name that’s confusing. Legislation in BC allows M+S tires to be permitted during winter months on provincial mountain passes and highways that previously allowed only winter tires bearing the severe service designation.

However, Transport Canada and the Tire and Rubber Association of Canada say true winter tires provide the best safety in winter conditions. And it’s not just about severe snow and ice, which struck typically mild regions like Vancouver and Toronto last year. It’s about the temperature

So, what makes mud and snow tires different from winter tires, and why are winter tires so much safer in the cold and on snow and ice?

MUD AND SNOW TIRES

Symbol:

mud and snow, M+S

Tire family:

3-season (all-season)

Features:

  • Wider gaps between tread blocks wick away mud and snow (over summer tires).
  • Bigger tread blocks offer extra traction capabilities in mud and snow conditions (over summer tires).
  • As a 3-season tire, the rubber compound contains less natural rubber.

How it performs:

Thanks to its rubber compound, in temperatures of +7 C and below, mud and snow tires become cold and stiff, and won’t be able to offer reliable braking or cornering on ice or cold weather conditions.

It’s best suited for:

Mud and snow tires are suited to drivers who want a tire with a bit of mud performance in the warmer months and in regions that see temperatures above +7 C.

 

WINTER TIRES

Symbol:

3-peak-mountain-snowflake

 

When you see this peaked mountain with a snowflake in the middle, you’re looking at the severe service winter tire designation. That means this tire has met specific snow traction performance requirements set by the Tire and Rubber Association of Canada. All-weather tires actually belong to the winter tire family, and bear this symbol as well.

Tire family:

Winter Tires

Features:

  • Aggressive tread blocks dig into ice, snow and slush.
  • Wide grooves between tread blocks expel snow and slush.
  • Natural rubber in the tread compound helps winter tires stay soft, flexible and grippy in sub-zero temperatures.

How it performs:

Tires designed for use in severe winter conditions can handle both snowy, slippery roads and sub-zero temperatures. Compared to M+S 3-season tires, winter tires offer superior braking and cornering performance on wet and rough ice, soft and hard-packed snow, and slush.

We’ve got a great visual of the difference between all-weather tires, all-season tires, winter tires and studded tires.

Through Kal’s Tire Testing, we’ve also got some incredible third-party tire testing data so you can see how tires across categories actually perform in real winter conditions.

 

It’s best suited for:

Winter tires offer safer, more reliable performance for drivers who face temperatures at or below +7 C, ice, snow and slush. It’s also a safer option for those who travel through mountain passes.

In a news release about surging use of winter tires, Tire and Rubber Association of Canada (TRAC) president Glennn Maidment says more drivers on winter tires means our roads are safer for everyone.

“Every motorist needs to know that today’s high-tech winter tires radically outperform all-seasons in all cold-weather driving conditions and offer potentially life-saving benefits.”

Do you live in an urban centre or a region with mild winters, but you want more safety for unpredictable weather or trips through areas with common winter conditions in Canada? Meet the all-weather tire, a designated winter tire that doubles as a summer tire for reliable year-round use.
