<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of striking a balance between a dry operation stability and a snow operation stability. <P>SOLUTION: In the pneumatic tire 1, a land part 31 of a center region and a land parts 32 of right and left shoulder regions have a plurality of sipes 312 and 322 respectively. Moreover, ≥90% of the sipe 312 disposed to the center region comprise a two dimensional sipe, and ≥90% of the sipe 322 disposed to the shoulder regions comprises a three-dimensional sipe. A rubber hardness H1_ce at -10°C and a rubber hardness H2_ce at 20°C of the cap rubber 151_ce in the center region, and a rubber hardness H1_sh at -10°C and a rubber hardness H2_sh at 20°C of the cap rubber 151_sh in the shoulder region have a relationship such that H1_ce<H1_sh and H2_ce<H2_sh. <P>COPYRIGHT: (C)2013,JPO&INPIT |
