A pneumatic tire of braced tread construction has a tread width which is less than its bead width. The sidewalls of the tire each have a flex area located nearer to the tire tread than to the tire bead, which flex area is adapted to exhibit relatively greater flexibility than surrounding areas of the sidewall. The tire is adapted to have a run-flat capability, being of radial ply construction for increased sidewall flexibility, and, when mounted on a wheel, incorporating a lubricant to lubricate areas of contact between the bead and tread regions of the tire when the tire is flat.
