<p><P>PROBLEM TO BE SOLVED: To provide a pneumatic tire which improves uneven wear resistance performance. <P>SOLUTION: In the pneumatic tire including a belt and tread rubber at an outer side in a tire radial direction of a carcass with the carcass as a framework, the carcass extending in a toroidal shape between a pair of bead cores, a compression modulus of the tread rubber in a tread center region is higher than that in a tread shoulder region. The tread rubber is formed of a cap rubber layer for constituting a tread face, and a base rubber layer which is positioned at an inner side in a tire radial direction of the cap rubber layer, and has a higher compression modulus than that in the cap rubber layer. It is preferable that the thickness of the cap rubber layer in the tread center region is thinner than that of the cap rubber layer in the tread shoulder region. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
