Beschreibung
Zusammenfassung:	The invention relates to a sulfur curable (and cured) rubber composition which contains one or more pentaerythritol derivatives as pentaerythritol tetrabenzoate (PTB) and/or pentaerythritol tetrakis (3,5-di-tert-butyl-4-hydroxyhydrocinnamate) (PTHC) together with a low molecular weight polyester sebacate. Such combination of materials has been observed to increase resistance to tear for a rubber composition. The invention particularly relates to a tire having a component comprised of such rubber composition.
