Problems solved by technology

However, since the rigidity of the land part of the four-season tire decreases due to the increase of the sipe or the length of the sipe, there is a problem that the steering stability of the four-season tire on dry roads deteriorates.
In this way, there is a contradictory relationship between the improvement of braking performance on ice and snow roads and the assurance of handling stability on dry roads or wet roads, so it is difficult to balance the two.

Abstract

The invention provides a pneumatic tyre. The pneumatic tyre comprises a tread part and tyre shoulder parts positioned on the two sides of the tread part, wherein a V-shaped groove is formed in the tread part; two troughs of the V-shaped groove extend to different tyre shoulder parts and extend out of the tyre shoulder parts in the width direction of the pneumatic tyre. The pneumatic tyre has the advantages that as traditional sipes or cut grooves are replaced with the V-shaped groove formed in the pneumatic tyre, the pneumatic tyre has better brake performance on ice snow covered pavements, and the control stability of the pneumatic tyre can not be affected.

Description

technical field [0001] The invention relates to the technical field of tires, and more specifically, to a pneumatic tire. Background technique [0002] Pneumatic tires are one of the key accessories for normal driving of a car. There will be severe weather such as ice and snow in a year, but this kind of weather does not last for a long time. For such conditions of use, ordinary pneumatic tires are generally installed on cars. Four-season tires, and ordinary four-season tires are more difficult to brake and control when driving on ice and snow roads, the safety performance is also reduced, and traffic accidents are also frequent. However, replacing the snow tires in the special pneumatic tires is a waste of time and money, and if the car has been using snow tires to run on dry roads, it will increase the fuel consumption of the car, so it is more economical to use all-weather all-season tires. [0003] In the traditional technology, in order to make the four-season tire hav...
