A plurality of disposable single fabricated piece tire grips with friction contact surfaces and cable ties ratchet mounted on wheel contact surfaces of tires mounted on wheel hubs with openings allowing the grips to secure there through for easy application and fits all tires regardless of size.

A wheel traction device is adapted for providing traction for a wheel of a vehicle to escape from a mud ground during rotation of the wheel, and includes: a guiding unit having a guiding portion adapted to abut against the wheel; a bearing unit that is detachably connected to the guiding unit, and that has a bearing portion adapted to be positioned on the mud ground such that, during rotation of the wheel, the bearing unit and the guiding unit are prevented from being driven by the rotation of the wheel to move relative to the mud ground, thereby allowing the wheel to roll over the bearing portion under guidance of the guiding portion; and a fastening unit that detachably fastens the bearing and guiding units together.

A method for providing additional tractionability to a vehicle tire (20) for mitigating slippery road conditions such as ice and snow. The main embodiment for the main embodiment uses three cleats (26) per tire (20) and a cleat hub (28). Chain welts (32) and adjustable bungee cords (30) complete the install to form a contiguous unit gripping around the perimeter of the tire (20). All of the individual parts are lightweight for easy distribution to the tires (20) needing traction. They are easy to install. They are quick to install at roughly five minutes per tire (20). They are also both easy and quick to dismantle. Being solid bodied members, they are easy to keep clean by quickly hosing them down and they stack up for easy storage.

A traction device attachable to a wheel having a rim to which a tire is mounted. The traction device includes first and second gripping elements facing each other, the second gripping element being longitudinally movable between an extended position and a retracted position, the first and second gripping elements being closer to each other in the retracted position than in the extended position. When the traction device is operatively mounted to the wheel with the second gripping element in the retracted position, the traction device extends across the tire thread and the first and second gripping elements grip the wheel therebetween at the rim, and, when the second gripping element is in the extended position, the traction device is removable from the wheel.

A tire bar having an elongated body 11. A traction section 12 is disposed at a first end of the elongated body 11. The traction section 12 is configured to be mounted over a tire tread on a vehicle wheel. The traction section 12 has an inner surface 14 configured to contact the treads of a wheel and an outer traction surface 2 configured to contact a driving surface. The inner surface 14 opposes the outer traction surface 2. A lug contact section 16 has a lug connector 1 configured to contact at least one lug nut on a wheel. The lug contact section 16 is configured to be movable along a length of the elongated body 11 to vary a distance between the lug section 16 and the traction section 12. A locking structure 4 is configured to lock the lug contact section 16 at a position on the elongated body 11. A method of unsticking a vehicle by rotating a wheel having the tire bar connected to the wheel.

Disclosed is an escape device for self-rescue in the case of an auto tyre being trapped in a pit, comprising a central positioning device, at least one tyre claw and a jacking device. The central positioning device is positioned and mounted at a central position of spokes of a tyre. The tyre claw and the central positioning device are fitted to each other and are clamped onto the tyre. The jacking device and the tyre claw are fitted to each other. The jacking device is further provided with a jacking head in contact with the pit ground. The jacking head protrudes out of an external rim of the tyre. The escape device can carry out effective rescue for trapped tyres, is convenient and fast to assemble and disassemble, saves time and energy, improves driving safety, and reduces the occurrence of accidents.

Disclosed is a portable escape device for self-rescue in the case of an auto tyre being trapped in a pit, comprising support posts, a clamping device fitted to the support posts, and a jacking device fitted to the clamping device. The support posts are fixedly mounted onto spokes. The clamping device clamps an auto tyre. The jacking device protrudes and extends out of a top face of a tyre portion. The portable escape device for self-rescue in the case of an auto tyre being trapped in a pit can release the trapped auto tyre and perform self-rescue fast and reliably, and is convenient to carry.

This present invention relates to an anti-skid device adapted to being mounted on tyres of the vehicle wheels to provide traction and wheel to ground contact enhancement in snowy and icy conditions. The device includes a central housing (2) from which protrudes radially three arms (3) which are extended at the outer end by anti-slip components (10) transversally embracing the tread of the tyre. The anti-skid device has a locking mechanism that consists of a locking element (24) with teeth engaging with teeth on the inner circumference of the housing (2). A handle 16 integrated into the hub (4) interfaces with the locking element (24) to securely maintain the locked status when the device is mounted onto the wheel.
