Movement of rollers used for reforming an inner wall of a metal container bottom such as an aluminum beverage container is controlled at least partially using a rigid link coupled to other components of a reformer apparatus by a pin having a stepped profile. The stepped-profile pin preferably defines first and second shoulder regions. Undesired spaces or gaps in the pin-axial or thrust direction are reduced or eliminated by closely-positioning bushing flanges or thrust washers adjacent the shoulders.

The irrigation system of claim 4, wherein the cleats are connected to the tire assembly at the base so that the side walls extend outwardly from the tire assembly. 6. The irrigation system of claim 1, wherein the flexible member has an inner side engaging the outer periphery of the tires and an outer side that engages the ground, the outer side including elements that extend outwardly therefrom to provide traction and to direct water away from the travel path. 7. The irrigation system of claim 6, wherein the elements comprise a plurality of cleats extending across the width of the tire assembly. 8. The irrigation system of claim 1, wherein one of the two tires has an inflation pressure of about half of the inflation pressure of the other of the two tires. 9. A tire assembly for moving a mobile irrigation system along a travel path; comprising: first and second tires each having an outer periphery and mounted side-by-side on an axle, wherein one of the first and second tires has an inflation pressure less than the other of the first and second tires, and a flexible member mounted about the outer periphery of the first and second tires, the flexible member having an outer ground engaging surface that engages the ground as the tires rotate to provide a surface area over which weight of the irrigation system is distributed to prevent formation of ruts. 10. The tire assembly of claim 9, further comprising cleat elements mounted on the flexible member to direct water away from a center of the travel path. 11. A device for mounting onto a tire assembly for moving a mobile irrigation system along a travel path, the tire assembly including first and second tires each having an outer periphery and mounted on an axle, wherein one of the first and second tires has an inflation pressure less than the other of the first and second tires, the device comprising: a flexible belt member having an inner surface that engages the outer periphery of the first and second tires and an outer surface that engages the travel path to provide a surface area over which weight of the irrigation system is distributed to prevent formation of ruts. 12. The device of claim 11, further comprising a plurality of cleat members spaced along the flexible belt member and extending across the flexible belt member to direct water away from a center of the travel path.
