[0005]本实用新型提出一种轮胎，解决了现有低扁平比与宽行驶面轮胎不能兼顾耐磨性、驱动性及排水性的技术问题，具有耐磨、驱动性及排水性好的特点
Benefits of technology
[0017] This utility model proposes a tire with a zigzag structure for the longitudinal grooves, and the width of the central first longitudinal groove is smaller than the width of the two second longitudinal grooves on both sides. This can improve the interlocking effect between the tread blocks, reduce deformation, especially under heavy load or sudden braking, it can reduce the deformation of the crown center, reduce slip wear, and increase some lateral engagement edges when turning, taking into account both straight-line stability and cornering support.

Abstract
This utility model proposes a tire belonging to the field of tire technology, including longitudinal grooves. Each longitudinal groove includes a first longitudinal groove extending along the centerline of the tire tread, and second longitudinal grooves distributed on both sides of the first longitudinal groove. The width of the first longitudinal groove is smaller than the width of the second longitudinal groove. Each longitudinal groove includes a first straight portion and a second straight portion. The junction of adjacent first and second straight portions defines a first inflection point offset to one side and a second inflection point offset to the opposite side. The first and second inflection points are alternately arranged along the circumference of the tire tread, with alternating arrangements between the first and second inflection points of adjacent longitudinal grooves, and between the first and second inflection points. A transverse groove connects at one end to the first inflection point of the longitudinal groove and at the other end to the second inflection point of an adjacent longitudinal groove. This utility model solves the technical problem that existing low-profile and wide-tread tires cannot simultaneously achieve wear resistance, traction, and water drainage, and features good wear resistance, traction, and water drainage.
