A pair of wheel chocks ( 10, 12 ), configured for placement under a resting tandem wheel (W) to maintain the wheel (W) at rest and for alternatively supporting a trailer tongue wheel (W<SUB>j</SUB>), are disclosed. The wheel chock ( 10 ) broadly includes a body ( 14 ) that defines an internal chamber ( 16 ) in communication with an open face ( 18 ) presented by the body ( 14 ). The body ( 14 ) presents a generally pyramidal shape and includes a pair of oppositely spaced sidewalls ( 20,22 ), a top surface ( 24 ) extending between and adjoining the sidewalls ( 20,22 ), and a first wheel supporting surface ( 26 ) and second wheel supporting surface ( 28 ) extending between and thereby enclosing the walls ( 20,22,24 ). Each wheel supporting surface ( 26, 28 ) includes a arcuate leading edge ( 60, 62 ) to complement the contour of the wheel (W) and enable the chock ( 10 ) to be easily placed under the wheel (W) in an optimal position. The top surface ( 24 ) includes an arcuate depression ( 32 ) operable to receive the trailer tongue wheel (W<SUB>j</SUB>). A substantially hollow tapered supporting leg ( 46 ) projects from arcuate depression ( 32 ) for support. The top surface additionally includes an open rim ( 36 ) which can at least partially receive a supporting leg of another similar configured wheel chock ( 12 ) to enable nesting of the chocks ( 10, 12 ).
