In one embodiment, said one or more feet can provide further stabilization of said vehicle step 100. In one embodiment, said wheel assembly 102 can comprise a first wheel 112a and a second wheel 112b connected by an axle 114. In one embodiment, said wheel assembly 102 can attach to said frame 101 at the base of said third step 104c. In one embodiment, said wheel assembly can permit said vehicle step 100 to be transported without lifting said vehicle step 100 off the ground. In one embodiment, said plurality of steps can be separated by a one or more step heights (comprising a first height 116a, a second height 116b, a third height 116c and a fourth height 116d). In one embodiment, said one or more step spacings can all be equal pursuant to OSHA regulations. Likewise, said plurality of steps can each comprise equal width and depth. In one embodiment, said first height 116a, said second height 116b, said third height 116c can be equal, and said fourth height 116d can be variable, as discussed below, and therefore can be set to be equal to said first height 116a.

In one embodiment, vertical positions of said adjustable step 104e can be secured by a fastener 422a and a fastener 422b. In one embodiment, said one or more fasteners can securely fixate said adjustable step 104e in predefined vertical positions based on the location of adjustment hole 424a, adjustment hole 424b, and adjustment hole 424c. In one embodiment, said adjustment hole 424a, said adjustment hole 424b, and said adjustment hole 424c can be mirrored so that said adjustment holes exist on both left and right sides of said adjustable step 104e. In one embodiment, said adjustable step 104e can be adjusted vertically by disengaging said fastener 422a and said fastener 422b, lifting or pushing down on said adjustable step 104e to desired position based on said plurality of adjustment holes, and reengaging said fastener 422a and said fastener 422b. In one embodiment, said adjustable step 104e can be adjusted to permit proper clearance of tire height in order to use said vehicle step 100.
In one embodiment, said adjustable step 104e is secured to remainder of said vehicle step 100 by said one or more hinges. In one embodiment, said vehicle step 100 is placed in desired position next to the truck wheel and said adjustable step 104e can be rotated so that said bracket 402 is located next to the inside wall of the truck wheel and the top of said adjustable step 104e (or said adjustable step 104d) sits on or above the truck wheel. In one embodiment, said adjustable step 104e can be rotated back so that said adjustable step 104e sits above said first step 104a so that said vehicle step 100 can be moved away from a truck or stored away.
FIG. 4E illustrates a detailed perspective overview of said adjustable step 104d.
FIGS. 5A and 5B illustrate a left side view of said vehicle step 100 with said adjustable step 104e retracted and said vehicle step 100 in movement, respectively. In one embodiment, said adjustable step 104e can be retracted from truck tire and placed in a condensed configuration 500. In one embodiment, said vehicle step 100 can be in said condensed configuration 500 prior and after use and during storage of said vehicle step 100. In one embodiment, said vehicle step 100 can be in a movement configuration 502. In one embodiment, said vehicle step 100 can be in said movement configuration 502 by first being in said condensed configuration 500, holding said handrail 106, tilting said vehicle step 100, and moving said vehicle step 100 by using said wheel 112a and said wheel 112b. In one embodiment, said movement configuration 502 can be placed back into said condensed configuration 500 after said vehicle step 100 has reached a desired location.
FIGS. 6A and 6B illustrate a perspective overview and a perspective rear view said vehicle step 100 aligned with a wheel 602. In one embodiment, said adjustable step 104d can rotate on said one or more hinges and rest on a top portion 604 of said wheel 602.
