Abstract
A pneumatic tire comprising a tread is provided. The tread includes a center land portion, a middle land portion, and a shoulder land portion, and multiple sipes are formed in the center land portion, the middle land portion, and the shoulder land portion. When, in lengths of the sipes in a longitudinal direction, lengths of components along a tire axial direction are defined as sipe lateral lengths, a total value of the sipe lateral lengths of all the sipes in a ground contact surface of the tread divided by an area of the entire ground contact surface of the tread is a value of 0.050 m/mm2 or more, and a rectangularity of the ground contact surface of the tread is between 0.60 and 0.70.

A pneumatic tire comprising a tread,
- the tread including:
- a pair of center main grooves;
- a pair of shoulder main grooves placed outward of the center main grooves in a tire axial direction;
- a center land portion partitioned by the pair of center main grooves;
- a middle land portion partitioned by each of the center main grooves and each of the shoulder main grooves;
- and
- a shoulder land portion placed outward of the shoulder main groove in the tire axial direction, wherein
- multiple sipes are formed in the center land portion, the middle land portion, and the shoulder land portion, and
- when, in lengths of the sipes in a longitudinal direction, lengths of components along the tire axial direction are defined as sipe lateral lengths, a total value of the sipe lateral lengths of all the sipes in a ground contact surface of the tread divided by an area of the entire ground contact surface of the tread is a value of 0.050 m/mm2 or more, and
