Abstract
The invention relates to a pneumatic tire with a toroidal shaped tire carcass having sidewalls and a tread. A typical method of allowing a tire to run even in a punctured state is a method of reinforcing the sidewall area to support the load in the airless state. The present invention discloses both sidewalls having a hoop ring circumferentially molded in-place at the middle portion of both sidewalls or as floating multiple hoop rings bonded in-place at the middle portion in the tire inside sidewalls for supporting the vehicle load in a run-flat condition.
