When storage moduli at 80° C. of the print, inner, and outer layers are respectively defined as E1.sub.80′, E2.sub.80′, and E3.sub.80′, and storage modulus variations α1, α2, and α3 at high temperature of the print, inner, and outer layers are respectively defined as α1=|E1.sub.25′−E1.sub.80′|/E1.sub.25′, α2=|E2.sub.25′−E2.sub.80′|/E2.sub.25′, and α3=|E3.sub.25′−E3.sub.80′|/E3.sub.25′, α1<α2 and α1<α3, and E2.sub.25′>E2.sub.80′ and E3.sub.25′>E3.sub.80′ are satisfied.

In a tire 2 of the present invention, sidewalls 6 each include an outer layer 6a, and an inner layer 6b disposed inward of the outer layer 6a in the axial direction. The inner side end, in the radial direction, of the inner layer 6a extends to a region between a bead 10 and a chafer 8. When Po represents a contact point, on an outer surface of the tire 2, at which the outer layer 6a and the chafer 8 contact with each other, an inner side end, in the radial direction, of the outer layer 6a is equal to the contact point Po. In the radial direction, an outer side end 44 of the chafer 8 is disposed outward of the contact point Po. In the radial direction, an inner side end 46 of the inner layer 6b is disposed inward of the contact point Po.
