HD700 pattern radial tire of car

Abstract

The invention aims to provide an HD700 pattern radial tire of a car, which is excellent in controllable performance, good in slippery road tire drainage capacity and excellent in road grabbing capacity. An outside transverse rigidity zone of an outside pattern area consists of transverse pattern blocks which are formed by barrier-type transverse groove interval treads. An outside vertical rigidity zone comprises a vertical rigidity zone I and a vertical rigidity zone II; the vertical rigidity zone I consists of continuous pattern blocks which are formed by oblique transverse groove interval treads; reversely-S-shaped grooves obliquely and transversely formed in the vertical rigidity zone II; barrier-type grooves are formed between two adjacent reversely-S-shaped grooves at intervals. An inside water discharging zone I of an inside pattern area consists of oblique grooves and barrier-type grooves; an inside water discharging zone II consists of transverse mutation grooves which are communicated with vertical grooves. The HD700 pattern radial tire is excellent in controllable performance, good in slippery road tire drainage capacity, excellent in road grabbing capacity and relatively wide in promotional value and practical value.

Description

technical field [0001] The invention relates to the technical field of radial tires, in particular to a HD700 pattern radial tire for cars with an asymmetrical tread pattern. Background technique [0002] As the proportion of China's tire production in the world's tire production continues to rise, in order to avoid the impact of a large number of low-priced tires in China on the domestic market, the technical barriers to tire technology in Europe and the United States are getting higher and higher, and the low-price advantage of Chinese tires has disappeared. Therefore, the design It is becoming more and more urgent to produce high-quality tires. Domestic tire companies are gradually investing funds and personnel in the research and development of high value-added products. Whether they can occupy a certain share of UHP tires (ultra-high-performance radial tires), which are mainstream in the European and American markets, And the outstanding features have become an effectiv...

Problems solved by technology

[0002] As the proportion of China's tire production in the world's tire production continues to rise, in order to avoid the impact of a large number of low-priced tires in China on the domestic market, the technical barriers to tire technology in Europe and the United States are getting higher and higher, and the low-price advantage of Chinese tires has disappeared. Therefore, the design It is becoming more and more urgent to produce high-quality tires. Domestic tire companies are gradually investing funds and personnel in the research and development of high value-added products. Whether they can occupy a certain share of UHP tires (ultra-high-performance radial tires), which are mainstream in the European and American markets, And the outstanding features have become an effective expression of the vitality of the enterprise. In various innovative research and development projects, the innovative design of the tread pattern is one of the important aspects. UHP tires have higher requirements on handling performance. The traditional symmetrical and directional pattern design and The existing asymmetric pattern tread can no longer fully meet the requirements of automobiles for high-performance tires. Therefore, a technical solution is urgently needed to solve this technical problem
