Nail-embedded snow tire

Abstract

The invention discloses a nail-embedded snow tire which comprises a tire body, a tire sidewall and a tread, wherein the tread is uniformly segmented into single-guide treads by using multiple inverted-V-shaped primary grooves and inverted-V-shaped secondary grooves in the same direction in the primary grooves; the tread adjacent to the tire sidewall is a tread I; the middle tread is a tread II; the inverted-V-shaped primary grooves and the inverted-V-shaped secondary grooves respectively run through one another in two sides of the tread II; and non-slip nails are arranged on the tread I, the tread II and the tread III and are respectively and linearly arranged. According to the nail-embedded snow tire disclosed by the invention, patterns are in the unique inverted-V-shaped single-guide design, and the linear stability and high speed performances of the tire are improved; and moreover, the inverted-V-shaped primary grooves and the inverted-V-shaped secondary grooves respectively run through one another in two sides of the tread, so that the water suction capacity and road holding force of the tire in the vehicle driving process are improved, a water film on an ice surface is easily broken, and the driving is relatively safe.

Description

technical field [0001] The invention relates to an automobile tire, in particular to a studded snow tire. Background technique [0002] When driving in winter, a layer of water film will be formed between the tire and the ice and snow road surface, which will reduce the friction between the tire and the road surface and cause the tire to slip. Winter tires are generally designed with a special tread pattern and rubber formula to increase the friction between the tire and the ice and snow road. Compared with ordinary tires, winter tires are characterized by more fine patterns on the tread and good grip performance; the tread hardness is small, and white carbon black is added to the tread rubber, so that the tire is in close contact with the smooth ice and snow road surface, and the friction force is large ; When the temperature is lower than 10 ℃, the tread of winter tires is still relatively soft. Therefore, winter tires have better handling, passability and safety on ice a...

AI Technical Summary

Problems solved by technology

[0004] 1. The distance between the anti-skid stud and the knife groove is poorly designed, causing the anti-skid stud to fall off early;

[0005]2. The thickness of the base rubber under the stud is not enough, which leads to early damage to the crown belt during the driving of the tire;

[0006]3. Poor tread design, resulting in poor tire self-cleaning performance and lack of maneuverability
