ABSTRACT:
A winching and traction intensifying device for extricating an immobilized rubber tired vehicle. The device has a traction intensifying portion secured to a driving tire and an anchoring portion connected to the traction intensifying portion. A corresponding non-driving tire secures the anchoring portion through the weight of the vehicle itself to establish a necessary fixed point for the winching device while, simultaneously, the traction intensifying portion is coupled to the driving tire.
