A snow chain system that attaches to the frame of a semi-truck and/or trailer, or a large commercial construction vehicle. The system includes a removable chain box, a chain barrel, a chain spreader, flashlight driver notification, a drag brake, a box swivel, and tire clamp. The snow chain is rolled out of the chain box directly onto a tire tightly with minimal human involvement. It provides for installed a tight snow chain onto the tire when rollout of the snow chain to the tire is completed. After snow chain use, it rolls up manually back into the chain box and is ready for immediate service should another need arise. All necessary equipment is organized, helping the driver with safety concerns.

The invention relates to an anti-skid chain (1) for tires (3), in particular for bogie axles, wherein the anti-skid chain (1) has two laterally stable guide chains (5) which, when installed, are arranged to the side of the treads (9) of the tires (3), wherein the anti-skid chain (1) has a flexible chain mesh (7) which extends between the two guide chains (5), and wherein at least one guide chain (5) has chain links (15, 17) which are interconnected in an articulated manner by means of joint pins (19) in the circumferential direction (U), and at least one rotation-blocking element (27) by means of which a maximum joint angle (35) between two interconnected chain links (15, 17) is a defined. In order to prevent lateral pulling of the anti-skid chain (1) and, at the same time, to provide an anti-skid chain (1) that is easy to produce, according to the invention, a part of the rotation-blocking element (27) is located on at least one of the joint pins (19).

An extended-life tire chain and method of extending the life of a tire chain. An extended-life tire chain has a plurality of chain links, a plurality of twin clevises each secured to two of the links, and a plurality of clevis pins each having a head on one of its extremities. Each twin clevis has two receptacles. Each clevis pin is removably disposed in a different one of the receptacles. The twin clevises are oriented such that, when the tire chain is installed on a tire, the heads project radially away from a tread surface of the tire.

A tire traction assembly for mounting upon a tire. The assembly includes a plurality of flexible members such as chains or cables engaged in pivoting connections with brackets at opposing ends. A separable adjustable connector such as a toothed member is attached to a first of the two brackets and configured for engagement with a ratchet mechanism attached to the second of the brackets to releasably secure the tire traction assembly around the tire. A plurality of traction cables configured to traverse the rolling surface of the tire are located in-between the brackets. The brackets may include a planar tread plate which has opposing planar side surfaces configuring the brackets to a U-shape.

An automotive tire non-skid device for snowfields to increase adhesion to pavement covered with ice or snow, in particular to a diagonal bead chain stress reducing pinch plate and a diagonal bead chain. Through configuration of stress reducing pinch plates and stress reducing transition chains disposed on two sides of a second connecting assembly, concentrated stress at the connector roots of steel cables of the stress reducing transition chains are isolated, dispersed and relieved, and the service life of the steel cables are prolonged. At the same time, the present invention has the advantages of simple structure, stable performance, convenient modification and low manufacturing cost.

A traction increasing wheel accessory system for vehicles includes a plurality of anti-skids, an outer chain, an inner chain, an outer fastener, and an inner fastener. Each anti-skid includes a cross body, an outer shoulder body, and an inner shoulder body. The inner shoulder body is terminally connected to the cross body. The outer shoulder body is terminally connected to the cross body, opposite of the inner shoulder body. The outer chain is externally engaged with the outer shoulder body of each of the plurality of the anti-skids. The inner chain is externally engaged with the inner shoulder body of each of the plurality of the anti-skids. The outer fastener and the inner fastener are terminally attached to each end of the inner chain and the outer chain, thus allowing the accessory system to wrap around a wheel assembly.

System for attaching a tread formed as an elongated element to a tyre, such as a bicycle tyre. The system comprises at two elongated attachment members configured to be fastened along the circumference of a side of the tyre. The element and the members are provided with mutually interlocking means for engagement with each other when the element is attached to the tyre. The mutual interlocking means may be a zipper, or a hook-and-loop system, or a dual-lock system.

The present invention relates to an automotive tyre non-skid device for snowfields to increase adhesion to pavement covered with ice or snow, in particular to a diagonal bead chain stress reducing pinch plate and a diagonal bead chain. Through configuration of stress reducing pinch plates and stress reducing transition chains disposed on two sides of a second connecting assembly, concentrated stress at the connector roots of steel cables of the stress reducing transition chains are isolated, dispersed and relieved, and the service life of the steel cables are prolonged. At the same time, the present invention has the advantages of simple structure, stable performance, convenient modification and low manufacturing cost.

A vehicle wheel includes a rim, an inflatable tire, a grounding tire, and a safety unit. The rim includes two tire engagement portions spaced from each other in a longitudinal direction. The inflatable tire is mounted around the rim and includes an inner annular bottom wall and two inner annular sidewalls respectively on left and right sides of the inner annular bottom wall. Each inner annular sidewall includes an inner side having a lip pressing against one of the tire engagement portions of the rim. The grounding tire is mounted around the inflatable tire and includes an outer annular bottom wall capable of rolling contact with the ground. The safety unit is sandwiched between the inflatable tire and the grounding tire to couple the inflatable tire and the grounding tire together, permitting synchronously rotation of the inflatable tire and the grounding tire while increasing the anti-slipping effect.
