Patent granted for a tire with specific sipe design

A recently granted patent (Publication Number: US11912070B2) discloses a novel design for a vehicle tire, specifically focusing on the tread band. The tire features circumferential grooves and ribs, with a unique sipe design that includes a main portion and a top portion extending towards the outer surface of the tread band. The sipes also have opposite side wall portions that create deformations, enhancing the tire's performance. The top portion of the sipe widens progressively and symmetrically, with specific dimensions and ratios carefully defined to optimize the tire's functionality.

Furthermore, the patent details various aspects of the sipe design, including radial dimensions, transversal dimensions, and the shape of the deformations. The sipes are structured to interlock within the tread band, improving traction and grip on various road surfaces. The deformations within the sipes are polyhedron-shaped, with specific angles and inclinations to enhance the tire's overall performance. By focusing on the intricate details of the sipe design, the patented tire aims to provide improved handling, stability, and durability for vehicle wheels, catering to the diverse needs of drivers across different terrains and driving conditions.
