Ice and snow road car tires

Abstract

The invention relates to a tire tread, in particular to an ice snow covered pavement passenger car tire. The passenger car tire comprises a tire tread. A tread pattern is arranged on the tire tread and comprises an inner side shoulder part pattern, an inner side middle pattern, a middle pattern, an outer side middle pattern and an outer side shoulder part pattern. The middle pattern is located between the inner side middle pattern and the outer side middle pattern. The inner side shoulder pattern is located outside the inner side middle pattern. The outer side shoulder part pattern is located outside the outer side middle pattern. The inner side middle pattern is provided with inner side middle pattern blocks. The middle pattern is provided with middle pattern blocks. A three-dimensional circumferential groove is formed between the middle pattern blocks and the inner side middle pattern blocks. Continuous miniature edges are arranged at the bottom of the three-dimensional circumferential groove. Rhombic notches are formed in the two side walls of the three-dimensional circumferential groove at intervals. The problems that when a passenger car tire is used on an ice snow covered pavement, slipping happens and the brake distance is increased can be effectively solved, and the control stability of a passenger car is improved.

Description

technical field [0001] The invention relates to a tire tread, in particular to a car tire on ice and snow roads. Background technique [0002] Ordinary semi-steel radial tires used in cars are hardened in winter due to the temperature drop, the friction coefficient between the tire and the ground decreases rapidly, and a series of problems such as slipping, increased braking distance, and non-wear resistance are prone to occur, which have a great impact on the vehicle's safety. Safe driving is greatly affected. [0003] At present, the car snow tires used on ice and snow roads are mainly divided into two categories, namely studded snow tires and non-studded snow tires. Although the studded snow tires have good braking and driving performance, they have bulges. The anti-skid studs are very damaging to the road surface and need to be installed, which is time-consuming and laborious. Some countries have legislated to prohibit the use of studded snow tires. In order to improve...
