ABSTRACT:
In a pneumatic tire, a block unit includes a center block and side blocks separated by a communication groove. Aspect ratios of the center block and the side blocks are approximately the same. The center block and the side blocks are arranged such that a longitudinal direction of a rectangle relating to the aspect ratio of the center block and longitudinal directions of rectangles relating to the aspect ratios of the side blocks are approximately orthogonal to each other. Size ratios of a short side of the rectangle relating to the aspect ratio of the center block and the long sides of the rectangles relating to the aspect ratios of the side blocks are in a range equal to or more than 0.90 to equal to or less than 1.10.
