Pneumatic tire

A pneumatic tire comprising

• a sidewall portion provided in its radially outer region thereof with side protectors protruding axially outwardly from the outer surface of the radially outer region,
• the side protectors arranged in the tire circumferential direction at intervals so that a grooved portion is formed between every two of the circumferentially adjacent side protectors, wherein
• a length in the tire circumferential direction of said grooved portion is in a range of from 50% to 70% of a length in the tire circumferential direction of the side protector on each side of said grooved portion when the lengths are measured at the same radial position, and
• each of the grooved portions is provided with a single projection, wherein
• said projection projects axially outwardly from the outer surface of the radially outer region of the sidewall portion, and a protruding height thereof measured in a tire meridian section including the projection is less than a protruding height of the side protector on each side thereof measured in a tire meridian section including the side protector,
• wherein
• in a tire meridian section including the grooved portion, said projection has a substantially triangular shape having a single apex which is a pointed top, the substantially triangular shape having a radially outer oblique side extending radially outwardly from the single apex, and a radially inner oblique side extending radially inwardly from the single apex, and
• the length Li in the tire radial direction of the radially inner oblique side is greater than the length Lo in the tire radial direction of the radially outer oblique side.
