[0002] With the development of the automobile market and the world's low-carbon environment requirements, automobile users are paying more and more attention to the low rolling resistance performance of tires. Tires are important components for automobile driving. The energy loss of tires during driving accounts for a large proportion, about 5-15% of the energy loss. Reducing tire rolling resistance by 10% can reduce vehicle fuel by about 2%. Therefore, tire rolling resistance has a certain contribution to reducing vehicle fuel consumption or increasing endurance.
[0003] Among them, rolling resistance is the embodiment of all energy losses related to rolling when the tire is loaded. Since most of the energy is dissipated through hysteresis loss when the tire material is deformed, when the tire contacts the road, each point on the tire will undergo a deformation cycle for each rotation, and this deformation is most significant near the road contact area. In order to solve the above problems, a low rolling resistance tire is proposed. Summary of the invention
