A vulcanizable rubber composition comprises an interpenetrating or ionic network (IPN)-promoting resin. The resin comprises side chain functional groups along the resin backbone, which, in the presence of an additive material, form the connections that make up the IPN. In one embodiment, such material is ZnO. A method for forming the rubber composition comprises, in a productive step, mixing the product of the non-productive step, the zinc oxide, and a resin derived from maleic anhydride. The zinc oxide and the resin are simultaneously added to the composition during the productive mixing stage. The rubber composition can be cured and incorporated in a tire component, such as, a tread.

It has been unexpected found that silylated triglyceride oils can be incorporated into tire tread rubber formulations that include reinforcing fillers to provide improved wet traction characteristic, rolling resistance, and tread-wear without compromising cured stiffness (dry traction) and ultimate properties (chip/chunk resistance). The level of silica coupling agent needed in such formulation can also typically reduced. The present invention more specifically discloses a rubber formulation which is comprised of (1) a rubbery polymer; (2) a reinforcing filler, such as silica or carbon black; and (3) a silylated triglyceride oil. The silylated triglyceride oil will include silyl groups of the structural formula: &#x2014;(CH)&#x2014;Si(OR), wherein n represents an integer within the range of 1 to 8, and wherein R represents an alkyl group containing from 1 to 8 carbon atoms.
