A vulcanized tire product comprising a rubber composition said tire product selected from the group consisting of a pneumatic tire, a tire tread, a tire subtread, a tire sidewall, a tire body ply skim, a tire bead filler, a hose, and a belt wherein the rubber composition comprises a rubber and an aqueous or dried composition consisting essentially of defatted soy flour and natural rubber,
- wherein the natural rubber is non-carboxylated and non-sulfonated,
- wherein the aqueous or dried composition is present in an amount ranging from about 0.05 to about 200 parts, per hundred parts of the rubber,
- wherein the defatted soy flour present in the aqueous or dried composition ranges from about 0.05 to about 75 parts, per hundred parts of the natural rubber, and
- wherein the aqueous or dried composition is formed by solvating the defatted soy flour in a natural rubber latex, after which the combination is dried to form a dispersion of defatted soy flour in natural rubber.
