Abstract:
[Object] A motorcycle tire, for an uneven terrain, which exhibits both impact absorption and handling stability is provided.[Solution] A tire 2 includes a pair of rubber reinforcing layers 14 disposed inward of a carcass 10 near ends, respectively, of a tread surface 16. A profile of the tread surface 16 is formed by: an arc C1 that is disposed at a center, and that projects outward in a radial direction; and a pair of arcs C2 each of which is disposed outward of the arc C1 in an axial direction and each of which projects outward in the radial direction. The arc C1 contacts with the arcs C2. A radius R1 of curvature of the arc C1 is less than a radius R2 of curvature of each arc C2. Outer ends 40 of the rubber reinforcing layers 14 are disposed outward of ends TE of the tread surface 16 in the radial direction. Inner ends 42 of the rubber reinforcing layers 14 are disposed inward of the ends TE of the tread surface 16 in the radial direction. The rubber reinforcing layers 14 are not disposed on an equator plane.
