A pneumatic tire is provided in which markings shown on surfaces of side walls thereof have superior visibility and the effect of increased visibility can be maintained over a long period of time. In a pneumatic tire having a marking provided on a side wall, a marking area which includes the marking and a background portion of the marking is formed into a recessed plane which is recessed further inwards than the surface of the side wall in an axial direction of the tire, and the marking is formed in the marking area in the form of a projecting plane which is provided in such a manner as to project relative to the recessed plane. The surface of the marking is made up of a specular surface portion having a surface roughness in which a center line average surface roughness (Ra) is in the range of 0.4 to 1.5 mum, and the background portion is made up of a rough surface portion whose surface roughness exceeds a surface roughness in which Ra is 1.5 mum.
