Pneumatic tire

A pneumatic tire comprising

• a tread portion provided with a plurality of blocks divided by a plurality of main grooves extending continuously in the tire circumferential direction, and a plurality of axial grooves connecting between the main grooves,
• wherein
• the blocks include a siped block,
• the siped block is provided with a first sipe extending in the tire axial direction across the block so as to subdivide the block into two regions, and only two second sipes disposed within the respective two regions subdivided by the first sipe,
• the first sipe comprises
• a first portion including one end in the tire axial direction of the first sipe,
• a second portion including the other end in the tire axial direction of the first sipe, and
• a third portion between the first portion and the second portion,
• wherein
• the third portion extends straight while inclining with respect to the tire axial direction,
• the first portion has a wavy configuration extending in the tire axial direction from one end of the third portion while oscillating in the tire circumferential direction, and
• the second portion has a wavy configuration extending in the tire axial direction from the other end of the third portion while oscillating in the tire circumferential direction,
• the maximum depth of the first sipe is in a range of from 0.50 to 0.90 times the maximum depth of the main grooves,
• each of the second sipes is a closed sipe having both ends closed, and has an axial length (L10) in a range from 0.30 to 0.40 times the maximum axial length (L2) of the siped block, and
• the maximum depth of the second sipe is less than the maximum depth of the first sipe and in a range of from 0.20 to 0.50 times the maximum depth of the main grooves.
