RUN-FLAT AND AIRLESS TIRES

A tire (′) for rotation about an axis of rotation () has a first wall portion () having a partially conical form, and a second wall portion () integrally formed and interconnected with the first wall portion at a transition region () so as to define an annular recess. A closure-limiting configuration includes a number of tubular reinforcing elements () arrayed around the annular recess. Each tubular reinforcing element has a wall with a closed cross-section. The tubular reinforcing elements () are spaced around the annular recess such that deformation of a compressed region of the tire under a load causes a change in shape of the tubular reinforcing elements in the compressed region.
