The effect of tires on rolling resistance
Automobile tires have a direct impact on the fuel economy of the car. Reducing the rolling resistance of the tire can also improve the fuel economy of the car. Current cars use radial tires to reduce rolling resistance. That is to say, the impact of the tire on the energy consumption of the car is mainly caused by the rolling resistance, the rolling resistance increases due to the deformation of the tire, and the deformation of the tire is directly related to the speed of the vehicle. Therefore, the influence of the tire on the energy consumption of the vehicle depends on the environment in which the vehicle is used.
In the comparison test, it can be seen that the Michelin "fuel-efficient tires" worked hard on the material and pattern design, and far away from the general tires after stopping the engine's driving force at the same time. Its unique silicon-containing formula, GreenX technology, reduces vehicle fuel consumption. When driving, energy is consumed by various resistances. About 20% of the gasoline is consumed by the rolling resistance of the tire, and the new formula of fuel-efficient tread is effective. Reduce tire rolling resistance. If a car uses four “fuel-efficient tires”, it can reduce the fuel consumption by about 5% on average.
