Most drivers assume that as soon as the asphalt is clear of ice, the winter tires should come off. However, the real deciding factor isn't just the sight of pavement, it’s the consistent temperature.

According to Troy, the magic number is 7 degrees Celsius.

Wait for Consistency: You want the daytime temperature to stay consistently at or above 7C.

Morning vs. Afternoon: In Alberta, we often see "four seasons in one day." If it’s 10C at noon but still -5C during your morning commute, hold off just a little longer.

It might be tempting to leave those winter tires on until June just to be "safe" from a late-season flurry. However, Troy warns that this can be a costly mistake.

Winter tires are engineered with a specialized soft rubber compound designed to remain flexible in sub-zero temperatures. This flexibility provides the grip you need on ice. However, once the pavement warms up:

Accelerated Wear: That soft rubber becomes too soft. It begins to wear down rapidly against the hot asphalt, significantly shortening the lifespan of your expensive winter tires.

Decreased Handling: Winter treads are designed for snow displacement, not high-speed dry cornering. Driving on winter tires in summer can feel "squishy" and less responsive.

Fuel Efficiency: The increased rolling resistance of soft winter rubber means your engine has to work harder, costing you more at the pump.
