    Abstract: A lubricant composition for lubricating an interface between an inner surface of a tire and a safety support ring in a run-flat tire system that includes a lubricating agent selected from glycerol, polyalkylene glycol or combinations thereof and a thixotropic agent. The thixotropic agent is an organoclay comprising a mineral clay mixture treated with an alkyl quaternary ammonium salt, wherein the mineral clay mixture comprises at least one of sepiolite, palygorskite and a smectite and wherein a combined amount of palygorskite and sepiolite in the mineral clay mixture is between about 50 wt. % and about 100 wt. % with a balance of the mineral clay mixture being essentially the smectite. The lubricating agent may also be selected from a copolymer that is a mixture of alkylene oxides, preferably a mixture of ethylene oxide and propylene oxide.

    Abstract: The invention concerns a threaded component for a seizure-resistant tubular threaded joint wherein a lubricating substance is deposited in a thin film on at least the surface of the threads of the threading, said surface being treated to adsorb said lubricating substance. The lubricating substance consists of a homogeneous mixture of a) a thickening agent; b) a set of extreme-pressure additives physically and chemically compatible with the thickening agent and comprising at least an extreme-pressure additive with chemical action called chemical EP additive and capable of being used at Hertz pressures not less than 1000 Mpa's; c) an oil. The proportions of the constituents of the lubricating substance are selected such that said lubricating substance has a consistency capable of ensuring a self-induced and film-forming lubricating process. The invention also concerns a method for producing the thin film.
