PNEUMATIC TYRE WITH RUN-FLAT LUBRICATION

摘要

A tyre coating of a gelled non-volatile lubricating material for disposal on at least the interior surface of the tread to facilitate relative movement between contacting portions of the interior surface of the tyre when the tyre 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 tyre during inflated running.
