Problems solved by technology

In order to increase fuel efficiency, it is important to reduce the rolling resistance of the tire, however, the rolling resistance depends on the material and rigidity of the rubber, etc., so that there is a limit to improving the rolling resistance

Abstract

The invention belongs to the field of tyres and particularly relates to a pneumatic tyre. The pneumatic tyre is characterized by comprising following components in parts by weight: natural rubber, butadiene rubber, chlorinated butyl rubber, nitrile rubber, an ethylene-propylene-diene monomer, butadiene styrene rubber, carbon black N110, carbon black N22O, carbon black N326, a coupling agent, high styrene, reinforced resin and a vulcanizing agent. With the adoption of the formula and the components by weight parts, the produced tyre has the advantages of being capable of resisting partial abrasion, keeping the operation stability, preventing cracks of a thin film and effectively reducing the air resistance in the high-speed driving process; the tyre provided by the invention also has the good performances on stabbing resistance, slipping resistance, air resistance, ozone resistance, sunlight aging resistance and the like.

Description

technical field [0001] The invention belongs to the field of tires, in particular to a pneumatic tire. Background technique [0002] The tires are the ultimate executors of most steering commands on a vehicle. The tires on the vehicle bear the weight of the vehicle itself and the cargo, and transmit the driving force when the vehicle starts and the braking force when the vehicle stops to the ground. In order to reduce body vibration and maintain ride comfort, tires need to have cushioning performance and the ability to grip the road when turning. In this case, various stresses and deformations will be generated in various parts of the tire rotating on the ground. However, the loss modulus of rubber and cords, which are the constituent materials of the tire, is much greater than that of metal, so it will cause greater energy loss. This energy loss is converted to heat, which causes the tire temperature to rise. It is generally believed that the factors that affect tire h...
