Abstract
A tire has its tire cavity filled with inexpensive lubricated light cellular particles and thereby avoids deformation and flattening of the tire upon loss of inflation pressure while maintaining vehicular control.
Claims24
A tire mounted on a wheel rim so as to form a tire cavity which can be inflated with a gas under pressure, characterized by the fact that the tire cavity is filled at least partially with solid light-weight discrete particles of cellular material having a very low apparent density of less than about 100 g./dm.sup.3 but resistant to stresses due to tire travel, said particles bearing a lubricant which is inert with respect to the materials present in the tire cavity, thus, the particles are free to move relative to one another, with low friction and low generation of heat when they have to cushion the tire after a puncture of the tire cavity and plug the puncture hole.
