1. A pneumatic tire comprising:
a tread portion provided with a plurality of shoulder lateral grooves extending axially outwardly to the tread edge and then radially inwardly from the tread edge, and a plurality of shoulder blocks divided by the shoulder lateral grooves,
wherein
each of the shoulder blocks has an axially outer edge extending substantially straight and forming a part of the tread edge, and
each of the shoulder blocks has a side surface extending radially inwardly from the axially outer edge, wherein
the side surface includes a first surface section and a second surface section which are arranged in the circumferential direction of the tire, and protrude farther outward of the tire than the groove bottom surfaces of the shoulder lateral grooves,
in a tire meridian section including the first surface section, a profile line of the first surface section extends straight from the axially outer edge to a position corresponding to a position of the radial inner end of the shoulder lateral groove, and
in a tire meridian section including the second surface section, a profile line of the second surface section extends in a concave shape from the axially outer edge to a position corresponding to the above-said position of the radial inner end of the shoulder lateral groove through a path inward of the tire than that of the profile line of the first surface section.
