In a transporting system, a first conveyor includes a transport surface to transport different size tires in a first direction. A first positioner positions an end of a tire transported by the first conveyor, at a first predetermined position in the first direction. A second positioner positions an end of the tire at a second predetermined position in a second direction horizontally perpendicular or substantially perpendicular to the first direction. The first and second clamping portion portions are at or adjacent to a clamping position, and pass through between a tire first portion at or adjacent to an end of the tire positioned by the first positioner and a tire second portion at or adjacent to an end of the tire positioned by the second positioner to clamp side surfaces of the tire.
