What is the function of tire treads?

The function of tire treads is primarily to push water and debris away from the contact surface between the tire and the road, which enhances traction. This is crucial for maintaining grip on wet or uneven surfaces, preventing hydroplaning, and ensuring that vehicles can safely accelerate, brake, and maneuver. The design and depth of tire treads create channels that direct water away, helping to disperse it and keeping the tire in contact with the road. This maximizes the tire's ability to grip the surface, thereby increasing safety and performance while driving. Tread design is specifically engineered to improve performance under various driving conditions.
