This invention relates to a tire with resistance to rim slip, namely slippage of a rubber tire on an associated rigid wheel rim of a tire/rim assembly. The invention relates to a rubber chafer component of a tire for seating the tire against a rigid tire rim. The rubber chafer component is comprised of a rubber composition which contains zinc rosinate within and on the surface of said rubber composition, and thereby the chafer component promotes an increased coefficient of friction of the chafer component against a rigid tire rim of a tire/rim assembly as compared to a more conventional zinc stearate contained in a tire chafer rubber composition. The zinc rosinate is a product of rosin acid and zinc oxide formed in situ within said rubber composition of is added directly to the rubber composition as zinc rosinate. The more conventional zinc stearate is a product of stearic acid and zinc oxide formed in situ within a rubber composition.
