Abstract
In a pneumatic tire, shoulder blocks are formed with one of two types of values for block width measured in the tire circumferential direction. A cross-sectional shape of a tread ground contact edge of the shoulder blocks with the smaller block width value when sectioned in a plan that includes a tire axial center is formed with a squared portion formed by a curved line having a radius of curvature of 10 mm or less, or is formed with a squared portion taper cut along a straight line having a length of 10 mm or less. A cross-sectional shape of a tread ground contact edge of the shoulder blocks with the larger block width value when sectioned in the plan that includes the tire axial center is formed with a rounded portion formed by a curved line having a radius of curvature of from 30 mm to 60 mm inclusive.
