Pneumatic tire

A pneumatic tire comprising:

• a tread portion which is provided with a plurality of main grooves extending in a tire circumferential direction, and a plurality of lateral grooves extending in a direction intersecting the main grooves, to form block rows,
• wherein at least one block row sandwiched between the main grooves includes blocks having a pair of longitudinal side surface portions facing the main grooves and a pair of lateral side surface portions facing the lateral grooves, in which the pair of longitudinal side surface portions includes a pair of first longitudinal side surface portions that has ridgelines inclined with respect to the tire circumferential direction, and a pair of second longitudinal side surface portions that has ridgelines shorter than the ridgelines of the first longitudinal side surface portions and inclined greater with respect to the tire circumferential direction than the ridgelines of the first longitudinal side surface portions, and intersects the first longitudinal side surface portions at an obtuse angle, and
• wherein the block comprises notches formed at central portions of the pair of first longitudinal side surface portions, a first sipe that is opened to the notches and connects the notches on both sides, and second sipes formed on both sides of the first sipe in the tire circumferential direction and having both ends thereof terminated within the block.
