1. A pneumatic tire, comprising:
a plurality of dimple groups formed in a tread surface,
the dimple groups being composed of a plurality of dimples disposed at intervals and aligned in a tire circumferential direction,
a ratio L/K being 3.5 or more and 7.0 or less, and
a minimum center-to-center distance L being 20 mm or more and equal to or less than a ground contact length,
where,
K is a minimum center-to-center distance between different dimples in an identical dimple group, and
L is the minimum center-to-center distance between dimples in different dimple groups, wherein
an inclined groove is formed in at least any one of regions bounded by two circumferential main grooves, the inclined groove comprising one end communicating with one of the two circumferential main grooves and another end terminating within a land portion or communicating with a main sipe,
a center of any one of the dimples in the dimple group is located within a range bounded by two parallel lines of the inclined groove that are parallel to a reference line of the inclined groove and located at a distance of 3 mm from the reference line of the inclined groove, and
the reference line of the inclined groove is a line connecting center points in a width direction at both ends of the inclined groove in an extension direction of the inclined groove in a case where the main sipe is not present, or in a case where the main sipe is present, the reference line of the inclined groove is a line connecting center points in a width direction at both ends of a recess portion consisting of the inclined groove and the main sipe.
