Tread pattern of passenger car

Abstract

The invention provides a passenger car tread pattern. The passenger car tread pattern comprises a central pattern block, an outer transition area pattern block, an outer tire shoulder area pattern block, an inner transition area pattern block and an inner tire shoulder area pattern block; central outer side longitudinal pattern grooves are formed between the central pattern blocks and the outer transition area pattern blocks, and auxiliary transverse pattern grooves A are formed in the outer transition area pattern blocks; concave transverse grooves A are formed in the outer tire shoulder area pattern blocks; auxiliary transverse pattern grooves B are formed in the inner transition area pattern blocks; inner transition area transverse pattern grooves are formed in the inner transition area pattern blocks; concave transverse grooves B are formed in the inner tube shoulder area pattern blocks; inner tube shoulder auxiliary longitudinal pattern grooves are formed in the inner tube shoulder area pattern blocks, accumulated water in a grounding area in the running process of the tire can be effectively removed, and through the pattern blocks with different sizes in the transition area and the tire shoulder area and the staggered arrangement layout, the cooperative improvement of the rolling resistance and the gripping performance of the tire is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle tires, in particular to a passenger car tread pattern. Background technique [0002] In recent years, the tire labeling laws issued by the European Union and other countries have put forward higher requirements on the rolling resistance and grip performance of tires. However, nearly half of the tires in my country still fail to meet the EU's second-stage standards. my country began to implement the "Green Tire Technical Specifications" in 2014 in response to tire labeling laws issued by countries around the world. The "Green Tire Technical Specifications" pointed out that green tires are energy-saving, environmentally friendly and safe radial tire products, which have low rolling resistance, Outstanding product features such as fuel consumption, excellent handling stability, and shorter braking distance. Studies have shown that reducing the rolling resistance of tires by 15% to 30% can save fuel c...

Problems solved by technology

However, due to the varying degrees of incompatibility between rolling resistance and grip performance, there are few tread pattern designs that can synergistically improve tire performance.
