Abstract: A vehicle wheel assembly and a method of making the wheel assembly. In one embodiment, a wheel assembly may include a rim, a hoop member, and a resilient member. The hoop member may be disposed around the rim and spaced apart from the rim. The resilient member may be disposed around the hoop member, and portions of the resilient member may protrude through openings in the hoop member toward the rim. A tying member may tie each protruding portion to the rim, and the tying members may remain in tension while the wheel assembly is unloaded. In other embodiments, the wheel assembly may also include a second hoop member, or a traction layer, or both.

Abstract: An adjustable rim assembly 10 is provided for the wheel of a tractor or other industrial vehicle for changing the spacing of the opposed wheels of the vehicle. The mounting rail 20 is rigidly connected to the inwardly facing surface 22 of the rim base 12. Mounting rail 20 is formed in an accordion-like shape which forms a series of alternately axially spaced fore and aft planar mounting panels 24, 26, and mounting clamps 40 connect between the surfaces of the mounting panels and the opposed faces of the wheel disc 54. Various spacing of the wheel rim is achieved by changing the faces of the mounting panels 24, 26 to which the mounting clamps are connected.

Abstract: The invention provides for the retreading of tires in which the tire casing is stressed by fluid pressure inside the casing so that the casing is in a stressed condition when a new tread is applied thereto. The tire casing is stressed by positioning it on a rim and providing fluid pressure in the cavity between the rim and the casing with or without employing an expandible tube in the cavity.
