Claim Text:
1. A rubber compound comprising: an alkoxy-modified silsesquioxane comprising one or more compounds selected from the group consisting of alkoxy-modified silsesquioxanes having the formula and mixtures thereof, wherein w, x and y represent mole fractions, y does not equal zero, either w or x but not both can be zero, and w+x+y=1.00, wherein R 1 , R 2 , and R 3 are selected from the group consisting of (i) H or an alkyl groups having one to about 20 carbon atoms, (ii) cycloalkyl groups having 3 to about 20 carbon atoms, (iii) alkylaryl groups having 7 to about 20 carbon atoms, and (iv) R 5 X, wherein X is selected from the group consisting of Cl, Br, SH, S a R 6 , NR 6 2 , OR 6 , CO 2 H, CO 2 R 6 , SCOR 6 , OH, olefins, epoxides, amino groups, vinyl groups, acrylates and methacrylates, wherein a is 1 to about 8, R 5 is selected from the group consisting of alkylene groups having one to about 20 carbon atoms, cycloalkylene groups having 3 to about 20 carbon atoms, and R 4 and R 6 are selected from the group consisting of alkyl groups having one to about 5 carbon atoms, cycloalkyl groups having 3 to about 20 carbon atoms, and alkylaryl groups having 7 to about 20 carbon atoms; a reinforcing filler comprising silica or a mixture thereof with carbon black; an elastomer selected from the group consisting of: styrene/butadiene copolymer, polyisoprene, polybutadiene, butadiene/isoprene copolymer, butadiene/isoprene/styrene terpolymers, isoprene/styrene copolymer, natural rubber, butyl rubber, halobutyl rubber, ethylene-propylene-diene rubber and combinations thereof; and a catalyst for an alkoxysilane-silica reaction selected from the group consisting of: a strong inorganic base, an alkyl tin catalyst, a zirconium catalyst, a titanium catalyst, and combinations thereof; wherein the alkoxy-modified silsesquioxane has an 0 to about 3.8 percent of the about 8.5 to about 31.6 percent of the about 13.4 to about 39.6 percent of the about 21.2 to about 49.6 percent of the about 5.3 to about 36.2 percent of the
