[0023] The specific implementation process of the utility model is as follows: when a tire with low rolling resistance and high handling is needed, the weight of the traditional tire can be optimized and the air tightness of the tire can be ensured through the cooperation between the transition layer 1 and the airtight layer 2. The single-layer strength of the tire body can be ensured through the design of the sidewall 4 and the steel wire layer 3, and the phenomenon of frictional heat generation caused by the traditional two-layer tire body can be reduced, thereby reducing the rolling resistance of the tire, ensuring the rigidity of the tire sidewall 4, and improving the handling performance.
