20100012431	Tire step apparatus - A step apparatus is provided for use on a vehicle tire and includes a first step assembly which includes a first step portion and a pair of first struts extending upward from the first step portion. A second step assembly includes a second step portion. A pair of first bracket members partially support the second step portion, and a pair of second bracket members are telescopically adjustably connected to the pair of first bracket members. Hinge members are connected between the first struts and the front bracket portions. Locking means are provided for locking the first bracket members with respect to the second bracket members at a selected adjustment position, depending upon the width of the tire on which the apparatus is used. By adjusting the first bracket members and the second bracket members with respect to each other, the present apparatus can be used for a wide range of tires having a wide range of tire widths.	01-21-2010
