Tire tread refers to the patterned surface of a tire that makes contact with the road. It is designed to provide traction, helping vehicles grip the road and maintain control, especially in wet or slippery conditions. The depth and design of the tread can significantly affect a tire's performance, including its ability to channel water away and reduce the risk of hydroplaning. Different types of tire tread patterns are suited for various driving conditions. For example, all-season tires have a balanced tread design for general use, while winter tires feature deeper grooves and softer rubber to enhance grip in snow and ice. Proper tread maintenance is essential for safety and efficiency.
