<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of suppressing so-called center wearing. <P>SOLUTION: The pneumatic tire 100 has a central block line 28 located on a central region C of a tread 10, and lateral block lines 32A, 32B located on both lateral region S. All of the central block 22 and lateral blocks 26A, 26B are further partitioned into central block-like land portion 36 and lateral block-like land portions 46A, 46B by lateral sipes 34, 42A, 42B. The pneumatic tire 100 satisfies at least one of condition 1 in which circumferential shear rigidity (Gxc) of the central block-like land portion 36 is smaller than circumferential shear rigidity (Gxs) of the lateral block-like land portions 46A, 46B, and condition 2 in which compression rigidity (Ezc) of the central block-like land portion 36 is greater than compression rigidity (Ezs) of the lateral block-like land portions 46A, 46B. <P>COPYRIGHT: (C)2012,JPO&INPIT |
