ABSTRACT:
There is disclosed in the present application a traction device adapted to being mounted on a driving wheel tire of a vehicle for obtaining greater traction on ice or snow although the device may also be useful in certain types of mud. The device comprises four spring arms each including a textured traction portion positioned across the face of the tire tread. The device is quickly mounted over the tire by collapsing and spreading apart the tread portions to permit bringing the device into engagement with the tire from a radial direction. The four arms in two pairs are then disposed at right angles to each other and are thereafter simultaneously tightened into embracing generally equally spaced relationship with the tire by turning a spring loaded crank.
