Wheel Chock and Method

A system for blocking a wheel, the wheel including a rigid rim around which is mounted a tire having a circumferentially disposed resilient tire tread, the tire tread having an undeformed state and a substantially circular outer shape when away from the wheel chock, the system including:

• a wheel chock placed over a ground-anchored base plate establishing a latched engagement therewith to set the wheel chock in a tire blocking position, the wheel chock including a main body having a tire-facing side and a tire deformation cavity provided on the tire-facing side, a tire engagement zone located substantially at a top end of the main body and projecting from the tire-facing side above the tire deformation cavity and configured to initiate a local radial deformation of the tire tread and bring the tire tread into a deformed state when the tire tread is brought into direct contact with the tire engagement zone and the wheel is pressed onto the wheel chock;
• the tire deformation cavity being configured for receiving a portion of the deformed tire tread, the wheel exerting a horizontal force that is combined with a vertical local weight force acting on the wheel to create a resultant force vector at a center of the wheel, the wheel chock being configured and disposed to help maintain the resultant force vector in a path passing below the top end of the main body so as to substantially prevent the wheel from moving upwards relative to the wheel chock and ultimately rolling over the wheel chock.
