摘要:
A pneumatic tire for improving uneven wear resistance of a tread is provided. A pneumatic tire comprises a carcass serving as a framework and toroidally extending between a pair of bead cores, a belt and a tread disposed on a radially outer side of the carcass, wherein the tread comprises a plurality of tread rubber layers, dynamic elasticity of the outer tread rubber layer located in a radially outermost side of the tire is higher than dynamic elasticity of the inner tread rubber layer located in a radially innermost side of the tire, and a thickness of the inner tread rubber layer in a tire equatorial plane is smaller than a thickness of the inner tread rubber layer in other regions.
