PROBLEM TO BE SOLVED: To provide a pneumatic tire which compatibly realizes ice and dry performances at high levels. SOLUTION: A wavy sipe 10 formed in a block 1 consists of a first sipe part 11 forming a wavy shape by repeatedly disposing a first part 11a having an angle of±10°relative to a basic line SL and a second part 11b having an angle of±10°relative to a normal PLs of the basic line SL and of a second sipe part 12 forming a wavy shape by repeatedly disposing a third part 12a having an angle of±10°relative to a cross line CL intersecting with the basic line SL at an angle of 45°and a fourth part 12b having an angle of±10°relative to a normal PLc of the cross line CL. The first sipe part 11 and second sipe part 12 are respectively formed in the center region 1a and both end regions 1b of a block 1 at one cycle or more. COPYRIGHT: (C)2008,JPO&INPIT
