    Abstract: Lubricant compositions as well as methods and articles utilizing the lubricant compositions that comprise a polyoxyalkene as a lubricating agent, between 4 wt.% and 7.5 wt.% of silica as a thickening agent and an inorganic thixotropic-enhancing metal compound added in an amount of, for example, at least 20 ppm, by weight or alternatively, between 1 ppm and 2 wt.%. The silica may be fumed silica. Examples of the metal compound include KOH, NaOH, KCl, CaCl 2 , MgCl 2 , CaO, MgO, Mg(OH) 2 or combinations thereof. A tire is also included, comprising a radially inner face designed to be opposite a wheel rim on which it is designed to be mounted, wherein the radially inner face is provided with the lubricant composition described above.
