ABSTRACT:
A tire structure includes bag-like members capable of expansion and contraction and which are buried in anti-slip grooves in the tire surface, and an air supply coupled to the bag-like members for supplying air to inflate the bag-like members to cause them to expand and project outwardly of the tire surface. The air supply may include stems coupled to an air source in the wheel part of the tire structure. Normally, the tire structure can be run as a usual tire. When running on a frozen road or the like, the tire structure permits functions and effects like a tire with a chain coupled thereto to be obtained by a simple operation to inflate and expand the bag-like members to cause them to project outwardly of the tire surface, and without need of any cumbersome operation of mounting a chain to the tire.
