The invention belongs to the technical field of tires, and discloses a tire with knurls on the groove wall of a tread pattern groove, which comprises a tread, a plurality of longitudinal grooves are arranged on the tread along the circumferential direction of the tire, a plurality of transverse grooves communicated with the longitudinal grooves are arranged on the tread, a plurality of knurls are arranged on the groove wall of each longitudinal groove along the circumferential direction of the tire and the radial direction of the tire, and a plurality of knurls are arranged on the groove wall of each transverse groove. And the plurality of knurls form an annular knurled block. The knurls are additionally arranged on the groove walls of the longitudinal grooves, the knurls are designed to be different in depth and height, so that the area of the longitudinal grooves is increased, the water storage capacity of the longitudinal grooves is improved, the shapes formed by the knurls are chamfered with included angles, water flow in the longitudinal grooves can flow stably, the pattern wetland performance is improved, and the service life of the longitudinal grooves is prolonged. And other performances are maintained.

    本发明属于轮胎技术领域,公开了一种胎面花纹沟沟壁具有滚花的轮胎,包括胎面,所述胎面沿轮胎周向设置有若干纵沟槽,胎面上设有若干与纵沟槽相贯通的横沟槽,在所述纵沟槽的沟壁上沿轮胎周向和轮胎径向均开设有多个滚花,多个所述滚花形成环状的滚花块。本发明通过在纵沟槽的沟壁增加滚花设置,将滚花设置为不同深度、不同高度设计进行呈现,从而增加纵沟槽面积及储水能力,通过将滚花所形成的形状具有夹角的进行倒圆角设置,可使纵沟槽内的水流流动平稳,提升花纹湿地性能,其它性能维持。
