Pneumatic tire with specific groove configurations and dimensions
The granted patent US12059928B2 describes a pneumatic tire design characterized by a unique tread structure that includes two main grooves extending circumferentially, a center land portion, and shoulder land portions. The center land is partitioned by the main grooves and features a center auxiliary groove that is narrower and shallower than the main grooves. Additionally, the shoulder land portions are equipped with a shoulder auxiliary groove, which has a zigzag shape formed by two inclined groove portions. The design incorporates a specific ratio of the areas of the center and shoulder land portions within the ground contact area, ensuring optimal performance characteristics.
Further claims detail the angles of the groove center lines, which are strategically designed to enhance tire performance. The shoulder auxiliary groove is positioned towards the ground contact end of the shoulder land portions and may include dimples to improve traction. The center auxiliary groove's dimensions are specified to be significantly smaller than those of the main grooves, contributing to the tire's overall functionality. The patent also outlines the arrangement of lateral grooves that connect various components of the tread, ensuring effective water drainage and improved grip. This innovative tread design aims to enhance the tire's performance in various driving conditions while maintaining structural integrity.
