This disclosure related to a pneumatic tire which is collapsible in its uninflated shape. This disclosure relates to a pneumatic tire and the rim combination of the pneumatic tire and a rim wherein the bead areas of the tire are capable of rotating in their mounted, uninflated shape to attain a different configuration in their mounted, inflated shape. The tire may have the characteristic wherein the sidewalls are capable of being folded axially inwardly toward each other when the tire is mounted on the rim and uninflated. In the uninflated and folded shape the tire and the combination of the tire and rim of this disclosure conserve space and weight over a standard tire and tire and rim combination. This uninflated, folded feature is designed primarily to be used as a spare tire replacement in automobiles.
