Abstract
Method and device for enhancing the adhesion qualities of vehicle wheels through the use of a plurality of embedded members having exposed high frictional surfaces, which are capable of automatically being caused to attain frictional contact with a wheel bearing surface in response to slippage. Under normal conditions where enhanced friction is not needed, the embedded members lie in a relative retracted position from which they may respond to slippage conditions as needed.
