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.

A tire chain includes a side member. An attachment bracket is secured at a first end region to the side member. The attachment bracket is formed at a second end region with a slot and with a channel. A crosslink member has an endless link at one end. The endless link defines an opening and is located in the slot so that the opening intersects the channel. A rod extends through the channel and the opening of the endless link and is secured against removal from the channel, whereby the crosslink member is secured to the attachment bracket.

A supplemental tire tread for installation on an outer surface of a solid tire, the outer surface of the solid tire defining opposed sidewalls and a tread surface that extend between the sidewalls. The supplemental tire tread has a tread body having an outer tread surface, an inner surface, and an attachment for attaching the tread body around the tread surface of the tire. The inner surface of the tread body has tire supports with tire receiving receptacles that open away from the inner surface of the tread body and receive the solid tires when installed. The tread body has anchor receptacles that engage anchors that pierce the solid tires to support the tread body against relative rotation of the solid tire and the tread body.

An anti fall-off cable chain includes two side ropes, a transition chains and connecting pieces, wherein the two side ropes are arranged horizontally, the transition chains are longitudinally arranged between the two side ropes, and the side ropes and the transition chains are connected through the connecting pieces. Each connecting piece includes an attaching part to be attached to a side face of a tire, a side rope mounting part arranged at one end of the attaching part, and a transition chain mounting part arranged at another end of the attaching part. When pulled by the part, attached to the tread of the tire, of the transition chain to tilt upwards, the transition chain connecting pieces trend to draw away from the mounting holes and are limited by first upper limiting parts.

The present disclosure relates to a device for increasing traction, and, in particular, to a device to be fitted on a tire or wheel for increasing, enhancing, or improving, the traction, or friction, between the tire or wheel and a surface that the tire or wheel is in contact with. The device comprises two or more line structures, at least two of which configured for encircling along two sidewalls of the tire, respectively. The device further comprises a plurality of cross members configured for contacting a tread portion of the tire, the cross members comprising mechanism for connecting the two or more line structures together. At least one of the cross members comprises a strap made of a material comprising textile, one or more traction components attached to at least a surface side of the strap. The present disclosure further provides a strap suitable for use in the device.

An external tensioning anti-skid chain system for an automobile, whose characteristics include a number of U-shaped anti-skid boards with the same structure and a set of tightening mechanisms. The two vertical edges of the U-shaped anti-skid plate are attached to the inside and outside of a tire. The first section and the last section of the U-shaped anti-skid plate are connected by a buckle structure. The tightening mechanism is installed between two adjacent U-shaped anti-skateboards, and the U-shaped anti-skid plates are mutually connected by connection rings. The anti-skid chain system has a simple structure, making installation and disassembly very easy.

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.

A supplemental tire tread for installation on an outer surface of a solid tire, the outer surface of the solid tire defining opposed sidewalls and a tread surface that extend between the sidewalls. The supplemental tire tread has a tread body having an outer tread surface, an inner surface, and an attachment for attaching the tread body around the tread surface of the tire. The inner surface of the tread body has tire supports with tire receiving receptacles that open away from the inner surface of the tread body and receive the solid tires when installed. The tread body has anchor receptacles that engage anchors that pierce the solid tires to support the tread body against relative rotation of the solid tire and the tread body.
