Abstract
A rubber composition is disclosed wherein the rubber composition contains at least (a) a rubber component; (b) a silica filler; (c) a coupling agent; and (d) a cure-enhancing amount of at least one polyalkylene oxide having a weight average molecular weight less than 200. The compositions may also include suitable amounts of other ingredients such as carbon black, antiozonants, antioxidants, etc.
