Abstract: A tire system that includes a cylindrical metal rim with an outer surface and a plurality of solid tire segments, each of the tire segments having at least one track that is connected to a mounting plate, the mounting plates being circumferentially positioned adjacent to the outer surface of the rim. The tire system may be employed on an off-highway earthmoving machine such as a towed or other scraping device.

Abstract: The present invention relates to an anti-skid traction device designed to be easily mounted onto a wheel of a motor-vehicle for obtaining greater traction on ice, snow, mud, or sand. One embodiment of the invention is for uses in situations where an automobile has been impaired by road conditions. Another embodiment of the invention is for uses as a road travel device designed for more continuous use where supplemental traction is desired on a long-term basis. Another embodiment of the invention is for use by trucks and other heavier vehicles in severe road conditions. All the embodiments of the present invention are designed to replace snow chains which have already been outlawed except for use on emergency vehicles. The invention disclosed herein provides safety for the road, the environment and the user, in a cost effective manner.

Abstract: A tire protector device with a covering, especially formed by plates, which exhibits at its ends next to the outside of the tire connector parts for fastening a chain net which covers the side wall of the tire. The edge of said chain net remote from the connector parts being connected to a holding strand via connection parts which are formed of tension devices which have at least one tension spring forming a store of tensional force and/or which exhibits each a connector member carried movably on the holding strand.

Abstract: Traction augmenting ribs are formed of a semi-rigid material particularly well-suited for placement around a vehicle tire or the like. Each rib is formed of a pair of side arms and an interconnecting central portion which are arranged in a generally U-shaped configuration to fit around the vehicle tire. The side arms are formed of a bow-like spring arrangement which is flexible in response to application of forces at the ends thereof in a radially inward direction relative to the tire so that the side arm ends are positioned to displace the rigid interconnecting elements beyond the contour of the tire. Interconnecting linkages or cables are passed through the rib ends and are tightened in a circumferential direction so as to apply the radially inward force to the rib side arms. Reinforcing steel wires can be included throughout the length of each rib and reinforcing crossbars can be embedded within the central portion of each rib so as to facilitate accommodation of tires of varying tread widths.

Abstract: A pneumatic tire comprising a carrying case and a removable tread ring having an armor member resistant to tension in the longitudinal direction of said tread ring, said tread ring containing a layer of see-through elastomer covering the inside of the armor, a nondiscoloring polyurethane being the preferred see-through elastomer.
