The disclosure relates to a process for improving the processability, storage stability and/or cure rate of an uncured silica reinforced rubber composition where silica comprises the major filler in the reinforced rubber composition, which comprises combining a mixture comprising, rubber, silica and at least one organic compound having a low molecular weight and a functional group wherein said functional group is at least an epoxy group, such as an epoxy/ether, epoxy/hydroxyl, epoxy/ester, epoxy/amine, ether/amine, episulfide, episulfide/ether, episulfide/hydroxyl, episulfide/ester functional group located in a terminal or sterically unhindered position in the molecule of said organic compound where the molecular weight of said organic compound having a low molecular weight is less than 7,000, or the organic compound comprises an abietyl, styrenated resorcinol formaldehyde, or ester hydroxyl organic compound having a hydroxyl, ester, and optionally, an ether group, such as an ester diol.

1. A process for improving the processability, storage stability and/or cure rate of an uncured silica reinforced rubber composition where silica comprises the major filler in said reinforced rubber composition, comprising combining a mixture comprising rubber, silica and at least one organic compound of relatively low molecular weight comprising, an abietyl compound, or an ester hydroxyl organic compound containing at least one hydroxyl group, at least one ester group, and optionally an ether group, where the molecular weight of said organic compound of relatively low molecular weight is less than about 7,000, wherein said organic compound is ethoxylated (5 moles) dehydroabietylamine in admixture with dehydroabietylamine, ethoxylated (11 moles) dehydroabietylamine in admixture with dehydroabietylamine, or an ester diol, and combinations thereof.
