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., with improved abrasion performance, in particular for pneumatic tires, has the following composition:at least one vulcanizable
diene rubber selected from natural rubbers, synthetic polyisoprene rubbers, polyisobutylene rubbers,
polybutadiene 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 blacks, silicas, 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; andfrom 0.1 to 10 phr of at least one
vulcanization accelerator.
