Abstract
A self-contained anti-skid device to be used with a pneumatic tire (32) for boosting traction against slippery roadways covered with ice and snow while all designated characteristics of the tire against other road conditions are fully preserved, comprising: a plurality of projectable and retractable anti-skid pins (20) to be positioned radially at a tread (34) of the tire (32) for being projected from the tread (34), as often as required, when a plurality of expandable pneumatic chambers (26) adjacent to the pins (20) are pressurized using merely a fraction of the actual pressurized air of the tire (32). To retract the pins (20), air from the expandable pneumatic chambers (26) is released and preferably recycled back into the tire (32) through an air recycling device (64) implanted within the tread (34) and actuated by rotation of the tire (32) on a roadway. An air valve directs a flow of air from the tire (32) to the expandable pneumatic chambers (26) and therefrom preferably to an air recycling device. The air valve is controlled either manually (92) in the locality of the tire, remotely (100) within reach of a driver even while driving, or automatically (102), through a temperature sensing device implanted within the tread (34) as the tire (32) rotates over sporadically icy road conditions.
