In recent years, a new trend has been emerging in the winter tire segment: so-called “approved” tires, known in English as All-Weather tires. These tires are designed to perform in both winter and summer. The new technology relies on rubber compounds that stay flexible below 7 degrees Celsius—the critical threshold identified by leading laboratories where regular tires become harder and lose grip.

This means that “approved” tires can legally and effectively remain on a vehicle year-round. For buyers, this can translate into savings on seasonal tire changes compared to using separate winter and all-season tires.

If a customer asks about this type of tire, reassure them by pointing out the logo of a mountain peak with a snowflake in the center. This symbol certifies that the tire is recognized (“approved”) by government authorities.

But does that guarantee performance? Not necessarily. However, numerous tests—especially in Europe, where this technology has become very popular—show impressive results. The Automobile journalist assigned to this topic has tested models such as the Michelin CrossClimate 2, Nokian WRG4 and Outpost, Hankook Kinergy 4S, and even the Laufenn i-Fit 4 on luxury cars, regular sedans, and SUVs. So far, they’ve performed just as well as premium winter tires—even during the summer!

That said, before recommending such tires, make sure the customer isn’t a winter sports enthusiast traveling regularly on deeply snow-covered roads. Despite this, published test results consistently confirm that approved tires have exceeded expectations for snow traction—and naturally, they’ve also performed well on icy roads.

The first “approved” tires were created about ten years ago by Finnish manufacturer Nokian. The fifth generation, the WR G5, is already in production. Its main competitor is the Michelin CrossClimate 2 (a new version 3 is already available in Europe), while many other manufacturers are now investing in this technology. Perhaps Quebec consumers might fall in love with them?
