A vehicle track system to increase the contact patch of the tires on a vehicle for use in sand, snow, or soft soil is disclosed. The vehicle track system is a quickly installed vulcanized rubber sections draped over the tire and secured with very strong over-center latches. The over center latches are used for closing the wrapped rubber track with some fine threaded adjustment and an over center clamp. Steel pins are used to link the individual track to tread together. The over center clamp is adjustable in length, allowing for fine tuning of the fit of the track on the tire. The vehicle track system works for almost any size tire and provides more width for dual wheels. The vehicle track system is easily installable and provides a large footprint that enables a vehicle to cross terrain.

A tire traction and vehicle turning device attaches to a tire of a vehicle to dislodge the vehicle from unfavorable ground conditions, such as snow, ice, or sand. The tire traction and vehicle turning device includes a tire-mounting body, a plurality of gripping treads, and a tie-down. The tire-mounting body attaches to a tire of the vehicle. The plurality of gripping treads provides a separate surface for the vehicle to gain traction due to differing coefficients of friction between the plurality of gripping treads and the grounds surface compared to the tire and the ground surface. The tie-down is positioned through the rim of the wheel to secure the tire-mounting body to the tire. As the tire is rotated, the tire traction and vehicle turning device is positioned between the ground surface and the tire, lifting the vehicle and propelling the vehicle in the direction the rotating tire is pointing.

A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.

A paddle tire with a tire body and a plurality of paddles. The tire body has a right sidewall, a left sidewall, and an outer surface joining the right sidewall to the left sidewall. The paddles are affixed to the outer surface at discrete intervals around a circumference of the tire body and alternate between left-side paddles and right-side paddles. A right portion of each right-side paddle adjacent the right sidewall of the tire body has a first height and a left portion of each right-side paddle distal to the right sidewall of the tire body has a second height. A left portion of each left-side paddle adjacent the left sidewall of the tire body has a first height and a right portion of each left-side paddle distal to the left sidewall of the tire body has a second height. The second height is less than the first height.

There is disclosed a cleat apparatus mountable on a track of a tractor or similar vehicle. In an embodiment, the apparatus comprises an elongate frame having a first mounting bracket at a first end of the elongate frame, the first mounting bracket adapted to latch onto a first side of a track, and a removable second mounting bracket adapted to mount to a second end of the elongate frame, and to latch onto a second side of the track. The cleat apparatus is secured in position by the mounting brackets to provide additional traction for the track in more extreme operating conditions, including snow and ice in winter. This may significantly extend the utility of tractors which otherwise may sit idle during winter months.

An escape device for self-rescue in the case of an auto tyre being trapped in a pit includes 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 a wheel. 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 for self-rescue 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.
