Do I Need to Change All Four Winter Tires?

Cars driving in winter on snow

Wondering whether to replace all four of your winter tires or if two will suffice? Well, for the safest driving experience—and to comply with laws on some Canadian highways—mobile tire services recommend using four winter tires.

In places like BC, Canadian rules dictate that from October 1 to March 31, vehicles must sport winter tires and/or carry chains on certain routes, especially mountain passes. By having a set of four dedicated winter tires—two in front and two in the rear—you’re not only boosting your vehicle’s handling but also its safety.

Why Not Just Two Winter Tires?

You might recall a time when it was pretty standard to just swap out two of your all-season tires for a pair of winter ones, usually on the driving axle. This was thought to give enough traction for navigating those frosty winter roads.

But, guess what? Modern safety tests have shown that this isn’t really the best approach.

When the mercury drops below +7C, those all-season tires harden up, losing that crucial grip needed for effective braking and steering. On the flip side, both all-weather and winter tires are made of a rubber compound that stays supple, giving you that much-needed grip on icy roads, snow, slush, and even mud.

So, it’s super important to have a full set of four matching winter or all-weather tires when the temperature takes a dive.

Why a Matched Set of Four Winter Tires are Needed

Winter tires are at their best when they’re part of a matching set. Mixing and matching tires, especially with different wear levels, can throw off your car’s balance, affecting both safety and comfort.

When picking out a set of winter or all-weather tires, make sure they all share the same:

This uniformity is key for maintaining excellent traction, cornering, and braking in snowy conditions.

Why Tread Depth Matters

The depth of your tire tread plays a big role in how your winter tires grip those snowy roads.

Typically, a set of winter tires lasts about two to three seasons. However, if you’re often out and about in winter conditions, this can wear down the tread depth quicker.

It’s crucial to ensure all four winter tires have at least 6/32-inches of tread depth. And remember, if the tread dips to 2/32-inches or less, it’s time for a tire change.

Choosing the Right Winter Tires for Your Vehicle

Your mobile tire service can help you find the perfect set of winter tires or all-weather tires that fit your driving needs and budget. Also, don’t forget to peek at your vehicle’s owner manual for the recommended tire size, speed rating, and load capacity.

Stay safe and happy driving!
