PROBLEM TO BE SOLVED: To improve crack resistance and uniformity of lateral grooves.SOLUTION: In a pneumatic tire having lateral grooves spaced apart from each other in a tire circumferential direction on an outer surface of a tread part, in an inner cavity surface of the tread part, there is provided a rib-forming region including at least one inward rib which projects from the inner cavity surface inwardly in a tire radial direction and extends in a direction intersecting the lateral grooves and across lateral groove-inward regions inward of the lateral grooves in the tire radial direction. |
