Abstract: Disclosed herein are methods for improving the rolling resistance of a tire rubber composition by providing a rubber composition including a rubber component which includes a majority by weight of guayule rubber where the guayule rubber includes a bagasse component, and a filler component where the filler component is free of silica, and including at least one silane in the rubber composition, where the at least one silane is selected from the group consisting of mercaptosilanes, blocked mercaptosilanes, and alkoxysilanes. Also disclosed is a tire rubber composition which comprises (a) 100 parts of a rubber component including a majority by weight of guayule rubber where the guayule rubber includes a bagasse component, (b) a filler component, where the filler component is free of silica, and (c) at least one silane selected from the group consisting of mercaptosilanes, blocked mercaptosilanes, and alkoxysilanes.
