1. A pneumatic tire comprising:
a pair of sidewall portions;
a pair of bead portions in which a bead core is embedded in each,
a carcass extending between the bead portions in a toroidal manner,, wherein
at least one of the pair of the sidewall portions is provided on an outer surface thereof with a first protruding portion arranged on an outer side in a tire radial direction and a second protruding portion arranged on an inner side in the tire radial direction,
each of the first protruding portion and the second protruding portion is formed so as to be convex outward in a tire axial direction,
the second protruding portion has a protruding apex surface formed of a different colored rubber material having a different color from that of an outer surface of the first protruding portion,
a distance (d1) in the tire radial direction between an inner edge in the tire radial direction of the first protruding portion and an outer edge in the tire radial direction of the second protruding portion is 40% or more and 220% or less of a length (L1) in the tire radial direction of the second protruding portion,
the different colored rubber material includes an extended portion extending radially outward beyond the second protruding portion in the at least one of the sidewall portions,
the carcass has a main body portion and turned up portions,
the main body portion extends between the bead cores of the pair of the bead portions,
the turned up portions are connected with the main body portion and are each turned up around the respective bead core from the inside to the outside in the tire axial direction so as to extend radially outward,
at least one of the turned up portions of the carcass is arranged axially inside the extended portion, and
a distance in the tire radial direction between an outer end in the tire radial direction of the extended portion and an outer end in the tire radial direction of the at least one of the turned up portions is 20% or less of the distance (d1) between the radially inner edge of the first protruding portion and the radially outer edge of the second protruding portion.
