TECHNICAL FIELD

[0001] The utility model relates to rubber tire technical field especially relates to a rubber tire noise reduction texture block. BACKGROUND

[0002] Tire is the round annular elastic rubber product that rolls and contacts with the ground on various vehicles or machines. It is usually installed on the metal rim, can support the vehicle body, buffer the external impact, realize the contact with the road and ensure the driving performance of the vehicle. The tire is often used under complex and harsh conditions, and it bears various deformations, loads, forces and high and low temperatures during driving, so it must have high load bearing performance, traction performance and buffer performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which shows that the rubber consumption of tire is very large. Automobile tires can be divided into pneumatic tires and solid tires according to the tire body structure.

[0003] Most modern cars use pneumatic tires. According to the air pressure in the tire, pneumatic tires can be divided into high pressure tires, low pressure tires and ultra-low pressure tires. Low pressure tires are commonly used on various vehicles. Pneumatic tires can be divided into two types: with inner tube and without inner tube. Most cars use tires without inner tube. According to the arrangement of the tire internal cord layer and the buffer layer, the tire can be divided into two types: radial tire and bias tire. The radial tire is commonly used on vehicles.
