Embodiment Construction

[0020] Such as Figures 1 to 3 As shown (for the sake of brevity and easy understanding of the view, figure 1 The horizontal fine lines 32 on the central land portion 3 and the concentric circular fine lines 8 on the pattern blocks of the secondary land portion 4 and the side land portion 5 are omitted in figure 2 The preset steel sheet 7) on the tire surface is omitted.

[0021] A pair of circumferential main grooves 1 and a pair of circumferential auxiliary grooves 2 are formed on the outer surface of the snow tire. The two circumferential auxiliary grooves 2 are located on both sides of the two circumferential main grooves 1. The sub-grooves 2 divide the tread into a central land portion 3 , two sub-side land portions 4 and two side land portions 5 .

[0022] The central land portion 3 is located between the two circumferential main grooves 1, the two auxiliary side land portions 4 are respectively located between the corresponding circumferential main grooves 1 and the ...

Abstract

The invention provides a snow tire. A tread is divided into a center land part, two auxiliary side land parts and two side land parts through two circumferential main slots and two circumferential auxiliary slots, wherein the center land part is provided with a circumferential shallow slot; a plurality of bulges are formed at the edges of the two sides of the center land part; a plurality of cross slots are formed in the outer surface of the tire; one end of each cross slot extends to the edge of the tread, and the other end of each cross slot extends to the circumferential main slot; bulges are formed at the edges of pattern blocks of the auxiliary side land parts; bulges are arranged at the edges of pattern blocks of the side land parts; circumferential annular slots are further formed in the side land parts; the circumferential annular slots are circumferentially formed along the outer surface of the tread; the circumferential annular slots are provided with a plurality of reinforcing ribs; the two sides of each reinforcing rib respectively extend to the wall of the circumferential annular slot. The circumferential main slots and the circumferential auxiliary slots form a design of four straight grooves of patterns, which sufficiently penetrate the cross slots, so that water drainage capacity on ice snow covered pavements and slippery pavements is improved; patterns on the two sides of the tread distribute in a V-shaped way, have directivity, break the ice snow covered pavements when the tire moves, and ensure that ice and snow and cumulated water are discharged to the two sides and the rear part.

Description

technical field [0001] The invention relates to a snow tire. Background technique [0002] Snow tires are suitable for use in snowy weather. Through specific pattern structures and the addition of metal nails, the grip of the vehicle can be increased while driving on snowy ground. However, the current snow tires have the following disadvantages: poor wet skid resistance, insufficient handling and insufficient snow safety. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a snow tire with good wet skid resistance and strong maneuverability. [0004] In order to solve the above technical problems, the present invention provides a snow tire; [0005] There are a pair of circumferential main grooves and a pair of circumferential auxiliary grooves on the outer surface of the tire. The two circumferential auxiliary grooves are located on both sides of the two circumferential main grooves. The two circumferential main g...
