Abstract
A safety tire comprising a tread (11), spaced beads (12) and sidewalls connecting the beads to the sides of the tread by forming under the tread a central inflatable chamber, each sidewall comprising an outside wall convex towards the outside and an inside partition convex towards the inside delimiting between each other lateral chambers distinct from the central inflatable chamber, characterized in that said lateral chambers are filled with a flexible cellular material rendering the sidewalls suitable to support the load of the wheel with a limited sagging of the tire in case of the deflating of the central chamber.
