Abstract: PROBLEM TO BE SOLVED: To improve the visibility of a mark, and to reduce rolling resistance.SOLUTION: There is provided a pneumatic tire 1 in which a serration 9 comprising a plurality of small grooves 10 is formed on an outer surface 3a of a side wall 3, and disposed at a tilting angle θ1a of 45 degrees or smaller with respect to a tire radial direction. A groove depth of each of the small grooves 10 changes between the outermost point 10g and the innermost point 10n in a tire radial direction, and each of the small grooves 10 has the deepest point 10a where the groove depth is the maximum. In a normal unloaded state that the tire is rim-assembled into a normal rim and filled with normal inner pressure, the deepest point 10a is formed in a range S which is a certain distance away from a tire maximum width position m to the outside in a tire radial direction at 0.2 to 0.4 times a tire radial distance Ha between the tire maximum width position m and the outermost end 1t in the tire radial direction.
