TIRE

Provided is a tire having a cross-sectional height (SH) ranging from 50 mm to 150 mm, in an unloaded state where the tire is mounted on a specified rim and inflated to a specified internal pressure, an opening distance (A) between the tire and a rim flange on a perpendicular line drawn from an outermost point of the rim flange in a radial direction to an outer surface of the tire with respect to the cross-sectional height (SH) satisfies a relationship 0.01≤A/SH≤0.16 and a projection amount (W) corresponding to one half of a difference between a total width of the tire and a rim width of the specified rim satisfy a relationship 0.03≤A/W≤1.60.
