摘要： A treaded traction cable device provided for use on a vehicle tire to increase traction in snow, ice or on other slippery or wet surfaces. It is intended for easy installation and extended use. The treaded traction cable comprises a pair of steel cable side members having first and second ends. A plurality of traversing cable cross members which secures a road gripping grade traction tire tread over the road gripping aspect of the underlying tire, also providing a plurality of extended traversing steel cable segments each with a steel ring on their ends, whereby providing connectability of the traversing steel cable cross members to the tensioning steel cable side members. On the first end of both steel cable side members a releasable connector mechanism for releasably connecting the first and second ends of each of the steel cable side members. The traversing steel cable cross members has ends and each of the ends have a steel ring attached. Each traversing steel cable cross members incorporates said treaded road gripping traction tire tread. The steel cable side members each have ends a first and second end. The first end is comprised of an adjustable leverage mechanism. The releasable connector mechanism includes a steel ring connected to the first end of each side member, a linked chain connected to said steel ring by a tempered steel releasable nullSnull hook or easily removable appropriate locking device, and a tempered-steel tightening lever. The second ends each comprised of a tempered steel ring used for leverage in conjunction with the previously mentioned tempered steel tightening lever. Other tensioning devices can be applied but do not change the spirit of this invention. Side cable rings used for interconnecting traversing steel cable cross members to the lateral side steel tension cable members. Lateral side traversing steel cable cross members need not be visible, that is, any type of durable covering can be applied as part of the tread mold or otherwise over the cable cross members for aesthetics. A durable ply material is bonded on the inner aspect of the device to inhibit the concern of separation of the road gripping traction tread from the traversing steel cable. Use of an embedded resistive material on the interior aspect of the said durable ply material provides added protection against slippage from the vehicle tires road gripping treads against interior of the said treaded traction device.

摘要： A heavy duty tire comprises a pair of axially outermost circumferential rows of shoulder blocks, each of the shoulder blocks provided with a circumferentially extending narrow groove, the narrow groove subdividing the shoulder block into an axially inner wide main part and an axially outer narrow lateral part, and the narrow groove is curved convexly so that the narrow lateral part is narrower in a middle region than both the circumferential end regions, whereby the heel and toe wear and shoulder wear and resistance to tear-off can be improved.

摘要： A drive-on system for installing a tire chain (i.e., snow chain) on a pneumatic tire mounted on a vehicle wheel. The system includes a U-shaped installation tool whose arms releasably engage fastening elements (hooks or links) at one end of each side chain, and a installation tray or ramp in which the connected tire chain and tool are arranged, and may be stored, prior to installation, with the tire chain in a partially laid-out orientation and the tool preferably within a tool compartment in the tray. To install the tire chain, the vehicle is driven onto the tray and stopped, preferably in a predetermined optimum position in response to a signal initiated by a position-indicating switch on the tray. Then the tool, with one end of the tire chain connected to it and trailing it, is drawn upward and circumferentially around the tire. With the tool bridging the tread of the tire so that its arms extend along the opposite sidewalls, the tire chain is draped and tensioned substantially in the correct position on the tire. The fastening element at the other, free end of each side chain is then removed from its place in the tray and connected to the mating fastening element. The connection on the inner sidewall is preferably made while the tool is still connected, which enables the arm of the tool on the inner sidewall to be used to guide the free element into contact and connection with the element connected to the tool.
