A vulcanizable elastomeric composition comprises a moisture stabilized polymer, a reinforcing filler comprising silica, a processing aid, and a cure agent comprising an effective amount of sulfur to achieve a satisfactory cure of the composition. The moisture stabilized polymer comprises the hydrolysis reaction product of a hydrolyzable substituent of an alkoxysilane terminated polymer reacted with a viscosity stabilizing effective amount of a viscosity stabilizing agent comprising a first long chain alcohol, prior to contacting the polymer with water. The processing aid is a second long chain alcohol, an alkyl alkoxysilane, or a mixture thereof.
