The tire cover includes a reinforcing structure for preventing the tire from collapsing when it is at least partially deflated, which reinforcing structure comprises a bias-ply carcass, a reinforcement layer of steel cord and a pair of side reinforcing layers embedded in the tire cover adjacent the respective side walls. The reinforcement layer has both ends terminating adjacent and in spaced relation to the bead cores within the bead portions and is made of a plurality of juxtaposed steel wires or cords.
