This invention relates in general to a traction device for a vehicle wheel and various attachment means therefor, and more particularly to a traction device with small teeth or protrusions on the inner surface of the gripping tread for limited penetration into the tread of the tire, larger teeth or protrusions on the outer surface thereof to provide a gripping surface and various attachment means for securing the device about the tire.
Various types of traction devices and means for attaching the same about a tire and wheel are known in the prior art. Many such prior art devices are quite inconvenient or nearly impossible to attach to the vehicle wheel or tire when the vehicle has lost effective traction of one or more of its motive wheels by becoming mired in mud, snow, ice, sand or the like. Frequently the vehicle operator gets soiled while attaching the device. Some prior art devices require deflation of the tire or even breaking the bead of the tire from the wheel rim. Rain, snow or other dampness usually reduces the coefficient of friction between prior art traction devices and the tire, permitting the traction device to slip radially about the tire during use. Another frequently encountered limitation of prior art devices is the necessity of removing the hubcap, tire or wheel to attach the device.
