Abstract:
      By taking 205/55R 16 passenger car radial tire as an example，a three-dimensional finite element model of the tire was established. Different tread patterns were designed for the same carcass，and the linear regression equation between the tire rolling resistance and contact characteristic parameters between the tread and carcass was established by using the principal component regression method. The effect of contact characteristics on the tire rolling resistance was studied.The results showed that the length factor of the second long axle，length factor of the third long axle，contact factor and contact shape factor had significant impact on the tire rolling resistance，the average contact pressure，length of the second long axle，length of the third long axle and length of long contact axle also showed influence but with less significance，and the maximum contact pressure and contact area only had small influence.
