Abstract: A pneumatic tire has a shoulder land zone provided with lateral grooves arranged at variable pitches in the tire circumferential direction and extending at an angle of not more than 30 degrees with respect to the tire axial direction. The domains defined between the shoulder lateral grooves include a smallest domain having the smallest circumferential length and a largest domain having the largest circumferential length. The domains are each provided with at least one sipe extending at an angle of not more than 30 degrees with respect to the tire axial direction. The number of the sipe(s) in the smallest domain is less than the number of the sipes in the largest domain.
