Document Type and Number:
Japanese Patent JP2017081545
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pneumatic tire and a cross-linking rubber composition excellent in abrasion resistance.SOLUTION: A pneumatic tire comprises: bead cores respectively provided for a pair of right/left bead parts; a carcass ply extending from a crown part through both sidewalls to both bead parts and moored by the bead cores; an inner liner disposed at the inner side in the tire radial direction in comparison with the carcass ply; and a tread disposed at the outer side in the tire radial direction in comparison with the carcass ply in which volume of a low density region is 35% or more and rigidity is 65 or more when elongated by applied stress of 1.5 MPa. A cross-linking rubber composition is given in which volume of a low density region is 35% or more and rigidity is 65 or more when elongated by applied stress of 1.5 MPa.SELECTED DRAWING: Figure 2
