ABSTRACT:
A tire chock for tandem wheels, for preventing unwanted movement of tandem wheel vehicles. The tire chock for tandem wheels comprises upper and lower opposing wedges which are sized for wedging engagement with facing tire tread surfaces of the tandem wheels to stop wheel rotation. Each wedge has arcuate diverging engagement surfaces generally conforming to the curvature of the tire tread surfaces. A threaded bar joins the upper and lower wedges and connects thereto so that rotation of the bar moves the wedges toward and away from each other. Also included is a handle connected to the bar for rotating the bar for moving the wedges toward and away from each other. There is also a member for locking the bar against rotation which comprises a first tab fixedly radially connected to the threaded bar and a second cooperating tab fixedly connected to the upper wedge. Both tabs have a lateral hole wherethrough the shackle of a padlock may be inserted simultaneously whereby preventing rotation of the threaded bar.
