Abstract:
1. A tire composition for forming a tire component, the composition formed by combining at least a preformed free-flowing filler composition and at least one vulcanizable rubber selected from natural rubbers, synthetic polyisoprene rubbers, polyisobutylene rubbers, polybutadiene rubbers, and random styrene-butadiene rubbers (SBR); the preformed free-flowing filler composition formed by combining at least an active filler and a first silane; the active filler including at least one of active filler selected from carbon blacks, silicas, silicon based fillers, and metal oxides present in a combined amount of at least 35 parts by weight per 100 parts by weight of total vulcanizable rubber, of which at least 10 parts by weight is carbon black, silica, or a combination thereof; and the first silane comprising at least one silated core polysulfide, wherein the silated core polysulfide is any of the isomers of 2-triethoxysilyl-1,3-bis-(3-triethoxysilyl-1-propyltetrathia)propane, 4-(2-triethoxysilyl-1-ethyl)-1,2-bis-(13-thethoxysilyl-3,4,5,6-tetrathiatridecyl)cyclohexane; 4-(2-diethoxymethylsilyl-1-ethyl)-1,2-bis-(13-triethoxysilyl-3,4,5,6-tetrathiatridecyl)cyclohexane; 4-(triethoxysilyl-1-ethyl)-1,2-bis-(10-triethoxysilyl-3,4,5,6,7-pentathiadecyl)cyclohexane; 1-(2-triethoxysilyl-1-ethyl)-2,4-bis-(10-triethoxysilyl-3,4,5,6,7-pentathiadecyl)cyclohexane; 4-(2-triethoxysilyl-1-ethyl)-1,2-bis -(9-triethoxysilyl-3,4 ,5,6-tetrathianonyl)cyclohexane; 1-(2-triethoxysilyl-1-ethyl)-2,4-bis -(9-triethoxysilyl-3,4,5,6-tetrathianonyl)cyclohexane; 2-(2-triethoxysilyl-1-ethyl)-1,4-bis -(9-triethoxysilyl-3,4,5,6-tetrathianonyl)cyclohexane; 4-(2-triethoxysilyl-1-ethyl)-1,2-bis -(8-triethoxysilyl-3,4,5-trithiaoctyl)cyclohexane; 1-(2-triethoxysilyl-1-ethyl)-2,4-bis-(8-triethoxysilyl-3,4,5-trithiaoctyl)cyclohexane; 2-(2-triethoxysilyl-1-ethyl)-1,4-bis-(8-triethoxysilyl-3,4,5-trithiaoctyl)cyclohexane; 4-(2-triethoxysilyl-1-ethyl)-1,2-bis-(7-triethoxysilyl-3,4-dithiaheptyl)cyclohexane; 2-(2-triethoxysilyl-1-ethyl)-1,4-bis-(7-triethoxysilyl -3,4-dithiaheptyl)cyclohexane; 1-(yl-1-ethyl)-2,4-bis-(7-triethoxysilyl-3,4-dithiaheptyl)cyclohexane; 2-(2-triethoxysilyl-1-ethyl)-1-(7-triethoxysilyl-3,4-dithiaheptyl)-2-(8-triethoxysilyl-3,4,5-trithiaoctyl)cyclohexane; 4-(2-triethoxysilyl-1-ethyl)-1,2-bis-(9-triethoxysilyl-3,4,5,6-tetrathianonyl)benzene; bis-[2-[4-(2-triethoxysilyl-1-ethyl)-2-(9-triethoxysilyl-3,4,5,6-tetrathianonyl)cyclohexyl]ethyl] tetrasulfide; bis-[2-[4-(2-triethoxysilyl-1-ethyl)-2-(9-triethoxysilyl-3,4,5,6-tetrathianonyl)cyclohexyl]ethyl] trisulfide; bis-[2-[4-(2-triethoxysilyl-1-ethyl)-2-(9-triethoxysilyl-3,4,5,6-tetrathianonyl)cyclohexyl]lethyl] disulfide; bis-[2-[4-(2-triethoxysilyl-1-ethyl)-2-(7-triethoxysilyl-3,4-dithiaheptyl)cyclohexyl]ethyl] disulfide; bis-2-[4-(2-triethoxysilyl-1-ethyl)-2-(7-triethoxysilyl-3,4-dithiaheptyl)cyclohexyl]ethyl] trisulfide; bis-[2-[4-(2-triethoxysilyl-1-ethyl)-2-(7-triethoxysilyl-3,4-dithiaheptyl)cyclohexyl]ethyl tetrasulfide; bis-[2-[4-(2-triethoxysilyl-1-ethyl)-2-(9-triethoxysilyl-3,4,5,6-tetrathianonyl)phenyl]ethyl] tetrasulfide; bis-2-[4-(2-triethoxysilyl-1-ethyl) -3-bis-(9-triethoxysilyl-3,4,5,6-tetrathianonyl)cyclohexyl]ethyl] trisulfide; bis-[2-[4-(2-diethoxymethylsilyl-1-ethyl)-2-(7-triethoxysilyl-3,4-dithiaheptyl)cyclohexyl]ethyl disulfide, and mixtures thereof.
