    摘要： The invention relates to a sulfur-vulcanizable rubber mixture, in particular for the sidewall of pneumatic vehicle tires, and a pneumatic vehicle tire, the sidewall of which at least partially consists of the rubber mixture vulcanized by means of sulfur. For reduced hysteresis, thus leading to low rolling resistance in the case of use as a sidewall mixture, the rubber mixture contains 20 to 80 phr of natural rubber and/or synthetic polyisoprene, 20 to 80 phr of at least one polybutadiene functionalized for bonding to silicic acid, and 20 to 50 phr of at least one silicic acid having a CTAB surface area (according to ASTM D 3765) of 50 to 130 m²/g nitrogen surface area (BET surface area) (according to DIN ISO 9277 and DIN 66132) of 60 to 140 m²/g.

    摘要： The invention relates to a pneumatic vehicle tyre of radial construction, in particular a utility vehicle tyre, having a belt assembly (3) consisting of at least three plies (8, 9, 10), specifically two working plies (8, 9) and a protective ply (10) disposed radially externally with respect to the working plies (8, 9), wherein each belt ply (8, 9, 10) has reinforcements (11) consisting of one or more steel filaments (11), wherein the reinforcements (11) in each belt ply (8, 9, 10) are in each case disposed parallel to one another and spaced apart from one another; the invention is characterised in that the steel filaments (12) of the reinforcements (11) of the protective ply (10) have a filament diameter between 0.10 mm and 0.35 mm, that the reinforcement diameter (13) is between 0.20 mm and 0.85 mm, that each reinforcement (11) of the protective ply (10) has a breaking strength between 15 kN/dm and 95 kN/dm and that these reinforcements (11) are disposed at a density between 50 and 120 ends per decimetre (epdm) in the protective ply (10).
