PROBLEM TO BE SOLVED: To provide a tire which has a cross-linked state of rubber optimized over the whole tire and is excellent in low heat generation performance.SOLUTION: A tire includes: a carcass ply which has a main body part extended in a toroidal shape between bead cores respectively embedded in a pair of bead parts and a ply edge part coupled to the main body part and is covered with a ply coating rubber; a belt part composed of a plurality of belt layers arranged on the outer side in a tire radial direction of the carcass ply; and a pair of side parts located on both edge parts of the belt part. Therein, all of Dvalues on following portions I,II,III and IV of the ply coating rubber are 160 Hz or more and a difference between the maximum value Drand the minimum value Drof the Dvalues on the following portions I,II,III and IV of the ply coating rubber is less than 35 Hz. |
