What is claimed is: 1. A tire composition for forming a tire component, the composition formed by combining at least:(a) a silated cyclic core polysulfide of the general formula[Y1R1Sx—]m[G1(SR2SiX1X2X3)a]n[G2]o[R3Y2]p wherein:each occurrence of G1 is independently selected from a polyvalent hydroca
What is claimed is: 1. A tire composition for forming a tire component, the composition formed by combining at least:(a) a silated cyclic core polysulfide of the general formula[Y1R1Sx—]m[G1(SR2SiX1X2X3)a]n[G2]o[R3Y2]p wherein:each occurrence of G1 is independently selected from a polyvalent hydrocarbon species having from 1 to about 30 carbon atoms containing a polysulfide group represented by the general formula:[(CH2)b—]cR4[—(CH2)dSx—]e;each occurrence of G2 is independently selected from a polyvalent hydrocarbon species of 1 to about 30 carbon atoms containing a polysulfide group represented by the general formula:[(CH2)b—]cR5[—(CH2)dSx—]e;each occurrence of R1 and R3 is independently selected from a divalent hydrocarbon fragment having from 1 to about 20 carbon atoms;each occurrence of Y1 and Y2 is independently selected from silyl (—SiX1X2X3), alkoxy (—OR6), hydrogen, carboxylic acid, and ester (—C(═O)OR6) wherein R6 is a monovalent hydrocarbon group having from 1 to 20 carbon atoms;each occurrence of R2 is independently selected from divalent hydrocarbon fragment having from 1 to 20 carbon atoms;each occurrence of R4 is independently selected from a polyvalent cyclic hydrocarbon fragment of 1 to about 28 carbon atoms or a polyvalent cyclic heterocarbon fragment of 1 to about 27 carbon atoms that was obtained by substitution of hydrogen atoms equal to the sum of a+c+e;each occurrence of R5 is independently selected from a polyvalent hydrocarbon fragment of 1 to about 28 carbon atoms or a polyvalent cyclic heterocarbon fragment of 1 to about 27 carbon atoms that was obtained by substitution of hydrogen atoms equal to the sum of c+e;each occurrence of X1 is independently selected from —Cl, —Br, —OH, —OR6, and R6C(═O)O—, wherein R6 is a monovalent hydrocarbon group having from 1 to 20 carbon atoms;each occurrence of X2 and X3 is independently selected from hydrogen, R6, wherein R6 is a monovalent hydrocarbon group having from 1 to 20 carbon atoms, X1, wherein X1 is independently selected from —Cl, —Br, —OH, —OR6, and R6C(═O)O—, wherein R6 is a monovalent hydrocarbon group having from 1 to 20 carbon atoms, and —OSi containing groups that result from the condensation of silanols; andeach occurrence of the subscripts, a, b, c, d, e, m, n, o, p, and x, is independently given wherein a, c and e are 1 to about 3; b is 1 to about 5; d is 1 to about 5; m and p are 1 to about 100; n is 1 to about 15; o is 0 to about 10; and x is 1 to about 10;(b) at least one vulcanizable rubber selected from natural rubbers, synthetic polyisoprene rubbers, polyisobutylene rubbers, polybutadiene rubbers, and random styrene-butadiene rubbers (SBR); and(c) an 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; andwherein the tire composition is formulated to be vulcanizable to form a tire component compound having a Shore A Hardness of not less than 40 and not greater than 95 and a glass-transition temperature Tg (E″max) not less than −80° C. and not greater than 0° C.
