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.

Abstract: Apparatuses, methods, and systems associated with traction devices for vehicle tires are disclosed herein. In various embodiments, a tire may include a tread material bonded with a casing, the tread material having a tread pattern and one or more tractive devices may be disposed within voids in the tread pattern. In some embodiments, a media passage may be disposed between the tread material and the casing substantially under one or more of the voids in the tread pattern, the chambers and/or channels being controllable to urge movement of a corresponding tractive device.
