Abstract: The low rolling resistance tires can effectively reduce the fuel consumption of the whole vehicle. In order to develop a low rolling resistance tire product suitable for light truck models, and verify the effect of reduced tire rolling resistance coefficient on tire grip performance, wear performance and vehicle fuel consumption, the paper starts from the design of tire rolling resistance reduction scheme, and uses the method of comparison and verification of low rolling resistance tire products and non-low rolling resistance products to verify the performance of vehicle braking, stability, wear and fuel consumption in detail. Through the test verification, the rolling resistance coefficient of the final developed low rolling resistance tire product is reduced by 17%, the fuel consumption of the whole vehicle can be reduced by about 5.35%, and the performance of braking, stability and wear can meet the needs of the whole vehicle.
