A pneumatic tire includes sipes disposed in a land portion formed in a tread portion, and pin holes for stud pins disposed in the land portion. The sipes are disposed at positions where a distance Ds from the pin hole and a diameter Dp of the pin hole satisfy (Ds/Dp)≥4.0. A sipe in which the distance Ds from the pin hole and the diameter Dp of the pin hole satisfy (Ds/Dp)≤5.0 is defined as a pin hole neighboring sipe. A sipe of which the distance Ds from the pin hole is the smallest, among the sipes in which the distance Ds from the pin hole and the diameter Dp of the pin hole satisfy (Ds/Dp)>5.0, is defined as a normal sipe. The pin hole neighboring sipe is formed in a high rigidity shape having higher rigidity than the normal sipe.
