TW201412572A - Tire tread structure with multiple asymmetric curved groove walls - Google Patents

Abstract

The present invention provides a tire tread structure with multiple asymmetric curved groove walls, which comprises a groove bottom, a first and a second side wall configured on both sides, and a pair of groove bottom chamfers. Each of the first and second side walls is respectively formed by a lower curved surface adjacent to the first and second groove bottom chamfers and an upper curved surface adjacent to the tire surface. Each of the upper and lower curved surfaces is respectively provided with a predetermined curvature, and both are connected as a continuous extension and together formed as an S-shaped or reversed S-shaped curved surface. Each of the groove bottom chamfers are respectively formed with a first and a second adjacent line at the adjacent location with the groove bottom. Each of the first and second side walls are respectively formed with a first ridge and a second ridge which are circularly configured on the tire surface of the tire in a wave shape with respect to each other. Each of the first and second adjacent lines is formed at the groove bottom in a wave shape. Thus, by utilizing the first and second side walls formed by two reversed arc-shaped surfaces in an asymmetric corresponding form to each other at both sides of the groove bottom, the present invention may improve the problem of the conventional tires which are easily jammed with stones, so as to avoid the occurrence of abnormal offset wearing, and may simultaneously achieve the effects of enhancing the water repelling performance of the main groove, increasing the ground gripping and maneuverability, and reducing resonance noise from air columns.
