How Winter Tires Interact with Modern Driver Assistance Systems (ADAS)

Driving in Canadian winters is challenging, but Advanced Driver Assistance Systems (ADAS) like “lane-keeping assist”, “automatic emergency braking (AEB)”, and “traction control” can make it safer. However, these systems rely on one critical factor—your tires. Winter tires play a vital role in how well ADAS functions when conditions get icy and snowy.

Traction Control and Winter Tires
Traction control helps prevent your wheels from spinning on slippery roads by adjusting power or braking. But it can only be as effective as the grip your tires provide. Winter tires are designed for better traction in cold weather, with specialized rubber that remains flexible and treads that improve grip. Without winter tires, traction control may struggle on icy surfaces.

​AEB and Stopping Power
Automatic emergency braking (AEB) is designed to stop your car when a collision is imminent. But on snow-covered roads, stopping distances increase dramatically with regular tires. Winter tires can reduce stopping distances by up to 30%, making AEB more effective when it kicks in during winter driving.

​Lane-Keeping Assist and Stability
Lane-keeping assist helps keep you in your lane by adjusting steering. However, this system requires good traction, which winter tires provide. Without the right tires, lane-keeping systems may struggle to correct your position on icy or snowy roads.

​Stability Control and Winter Tires
Electronic Stability Control (ESC) prevents your vehicle from skidding during sharp turns or sudden movements. Like traction control, ESC needs proper tire grip to function effectively. Winter tires ensure that ESC has the traction it needs to help maintain control in challenging conditions.

The Bottom Line
ADAS technologies greatly enhance driving safety, but they’re not a replacement for winter tires. These systems work best when paired with tires that are built for winter conditions. In Canada’s unpredictable winters, the combination of ADAS and winter tires provides the best protection on icy, snow-covered roads.

Stay safe this winter by ensuring your car is equipped with both—your tires and your ADAS systems work together to keep you on the road.
