What is the minimum tread depth for tires in Alberta?

In Alberta, the minimum legal tread depth for tires is indeed 1.5 mm. This specification is crucial for maintaining safe handling, traction, and overall vehicle performance, especially in adverse driving conditions such as rain or snow. Tread depth affects how well a tire can channel water away from the contact patch with the road, which is essential to avoid hydroplaning.

Having a minimum tread depth ensures that the tires maintain adequate grip on the road surface, which can significantly reduce stopping distances and improve safety while driving. If the tread is too shallow, the tires can lose grip, leading to dangerous situations, particularly during wet or icy weather.

Understanding the importance of tire tread depth is essential for safety on the road, and adhering to the legal requirements also ensures compliance with provincial regulations.
