Abstract: A wheel and solid rubber tire comprising a circular mounting disk having an axis perpendicular through the center of the circular disk. A wheel rim is rigidly affixed circumferentially around the mounting disk and has a cylindrical surface extending from one end of the rim to another and, axially aligned about the axis of the mounting disk. Multiple angled cross ribs having top and bottom edges rigidly affixed at the bottom edges to the cylindrical surface of the wheel rim substantially continuously thereacross at an angle from one end of the rim to the other and evenly spaced circumferentially therearound. One or more base layers of even thickness rubber are bonded to the cylindrical surface interposed between the angled cross ribs, and multiple additional layers of even thickness rubber are bonded to the one or more base layers with each additional layer bonded to the next so that a solid rubber tire is formed which is directly bonded to the wheel rim.

Abstract: A non-pneumatic tire for a wheelchair or other wheeled apparatus includes an endless integrally molded solid core rubber tire with a tensile member embedded in the tire to minimize chance of roll-off of the tire from an associated rim. A method for producing the tire is disclosed.

Abstract: A wheel of a track assembly of a crawler type vehicle has a resilient contacting element fixed about the wheel rim by first and second anchors. The anchors are slidably movable along angular end portions of a rim opening for securing the contacting element to the rim.
