Pneumatic tires and wheel rim assemblies

摘要

A tire having a coating of a gelled non-volatile lubricating material disposed on at least the interior surface of the tread to facilitate relative movement between contacting portions of the interior surface of the tire when the tire is driven deflated. The coating is incapable of flowing away from the portion of the interior surface to which it is applied either under gravity or under the forces generated inside a tire during inflated running.
