A pair of wheel chocks (10, 12), configured for placement under a resti ng tandem wheel (W) to maintain the wheel (W) at rest and for alternatively supporting a trailer tongue wheel (W j), 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 an d adjoining the sidewalls (20,22), and a first wheel supporting surface (26) and second whee l 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 j). 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 anoth er similar configured wheel chock (12) to enable nesting of the chocks (10, 12).</SDOAB >
