Abstract
A pneumatic tire includes a side wall having a side surface and a roughened region formed on the side surface such that the roughened region is extending in circumferential direction. The roughened region includes lands and dimples formed between adjacent lands, the lands include first lands and second lands formed such that the first and second lands are alternately arrayed in the circumferential direction and the first and second lands are inclined relative to radial direction in opposite inclination directions, and the roughened region is formed such that when the tire is mounted on a normal rim and filled with air at normal inflation pressure, the roughened region has an outer periphery formed on radially inner side of position 30 mm away in radially inward direction from tire maximum-width position, and the roughened region has an inner periphery formed on radially outer side of radially outer edge of the rim.
