  • Publication number: 20200055338
    Abstract: An object of the present invention is to provide a tire for two-wheel vehicle in which both the wet grip performance and the abrasion resistance of the tread are made compatible with each other. The tire for two-wheel vehicle of the present invention includes a pair of bead sections, a pair of side wall sections, and a tread section continuing to the both sidewall sections, the tread section being divided into three by a center section including a tire equatorial plane and a pair of shoulder sections including a tread end in the tire width direction, wherein a tread rubber of the center section and a tread rubber of the shoulder sections each contain a rubber component and satisfy the following formula (1): (Peak temperature of loss tangent tan ? of tread rubber of the center section)<(Peak temperature of loss tangent tan ? of tread rubber of the shoulder sections)??(1).

  • Publication number: 20200055337
    Abstract: The tire for two-wheel vehicles of the present invention includes a pair of bead sections, a pair of side wall sections, and a tread section continuing to both the side wall sections, the tread section being divided into three by a center section and shoulder sections, wherein a tread rubber of the center section and a tread rubber of the shoulder sections each contain a rubber component and satisfy formula (1) shown below. The tire for two-wheel vehicles of the present invention achieves both wet grip performance and abrasion resistance of the tread. (Dynamic modulus E? at 0° C. of tread rubber of center section)/(Dynamic modulus E? at 0° C. of tread rubber of shoulder sections)<0.
