Abstract: A skid prevention device for tires, which tires are provided with longitudinally- and radially-extending rows of treads separated by discrete, laterally-extending rows of recesses, includes a plurality of elongated, generally U-shaped metal claws disposed within the rows of the recesses of the tire, the outer ends of which have spikes secured thereto, and the inner ends of which are pivotably supportable in the recesses of the tire. The device also includes means for pivotably mounting the inner ends of the claws in the recesses of the tire for movement between an extended position, in which the claws are pivoted upwardly with their spikes extending radially outwardly beyond the upper surface of the treads of the tire, and a retracted position, in which the claws are pivoted downwardly with their spikes lying below the upper surface of the treads of the tire. In addition, the device includes means for pivotably moving the claws between the extended and retracted positions thereof.
