Patent ID: 8182626

Claim:
A tire composition with a Shore A hardness, according to DIN 53 505 and ASTM D2240, of not less than 40 and not greater than 95 and a glass-transition temperature Tg (E″max), according to DIN 53 513 with a specified temperature sweep of −80° C. to +80° C. and a specified compression of 10 +0.2% at 10 Hz, not less than −80 ° C. and not greater than 0° C., having the composition comprising: of at least one vulcanizable diene rubber selected from natural rubbers, synthetic polyisoprene rubbers, polvisobutvlene rubbers, polvbutadiene rubbers (BR), and random styrene-butadiene rubbers; from 35 to 300 phr of at least one active filler selected from carbon blacks, silicas, silicon based fillers, and metal oxides, of which at least 10 phr must be carbon black, silica, or some combination thereof; from 0 to 250 phr of other or further additives; from 0.1·10 −3 to 42·10 −3 mhr (mol per hundred parts of rubber) of a vulcanizing agent which crosslinks with a functionality>4; and from 0.1 to 10 phr of at least one vulcanization accelerator; and wherein the vulcanizing agent comprises a sulfur-containing structure of the general formula: G[C a H 2a —CH 2 —S x Y] n wherein G is a polyvalent hydrocarbon group and/or heterohydrocarbon group and or siloxane group containing 1 to 100 atoms; each occurrence of Y is independently selected from a rubber active group; and each occurrence of subscripts a, x and n are integers independently given by a is 0 to 6; x is 0 to 8; and n is 2 to 8.
