10. A tire for rotation about an axis of rotation comprising two sidewalls integrated with a tread to define a hollow tire,
each of said sidewalls comprising a first wall portion having a partially conical form circumscribing the axis,
said tread being integrally formed with said first wall portion and interconnected with said first wall portion at a shoulder region so as to define an annular recess adjacent to said shoulder region facing inwards towards a hollow of the tire,
the tire further comprising a closure-limiting configuration comprising a plurality of tubular reinforcing elements within said annular recess, each of said tubular reinforcing elements having a wall with a closed cross-section, said tubular reinforcing elements being circumferentially spaced around said axis within said annular recess such that deformation of a compressed region of the tire under a load causes a change in shape of said tubular reinforcing elements in the compressed region.
