What are Minor Tread Grooves?

Minor tread grooves refer to the finer grooves and patterns in the tire tread design that aid in enhancing the tire's performance, particularly in terms of traction and handling. These grooves play a significant role in the overall design of the tire, serving as an essential aspect of its functionality apart from the larger or major grooves. The primary tread design is crucial for channeling water away from the tire surface, improving grip on wet or slippery surfaces, and ensuring stability during various driving conditions.

Understanding minor tread grooves helps in assessing the tire's ability to perform safely and effectively. While other types of grooves or indicators may deal with wear or depth, minor grooves specifically contribute to the design framework of the tire's tread pattern, making them integral to a tire's overall performance profile rather than just an indicator of wear or defects.
