A spare wheel for automobiles which removably attaches to the wheel of a flat tire and permits movement of the vehicle without fixing or removing the tire. The spare wheel comprises a pair of rigid wheel segments of unequal size which are pivotally connected and together form a wheel having a diameter at least as great as the tire. The smaller segment pivots outwardly to permit attachment of the unit to the wheel of the flat tire, after which the vehicle is advanced until the segments can be returned to the wheel forming position. The edge of the first segment which is common with the second segment is arcuately shaped to permit it to roll in either direction notwithstanding composition of the road surface.
