Abstract: The invention relates to a sulfur-crosslinkable rubber mixture, especially for the sidewall of pneumatic vehicle tires, and to a pneumatic vehicle tire whose sidewall consists at least partly of the sulfur-crosslinked rubber mixture. For reduced hysteresis, hence leading to low rolling resistance when used as a sidewall mixture, the rubber mixture comprises 20 to 80 phr of natural rubber and/or synthetic polyisoprene, 20 to 80 phr of at least one polybutadiene functionalized for attachment to silica and 20 to 50 phr of at least one silica with a CTAB surface area (to ASTM D 3765) of 50 to 130 m2/g and a nitrogen surface area (BET surface area) (to DIN ISO 9277 and DIN 66132) of 60 to 140 m2/g.

Abstract: A pneumatic tire for vehicles has a belt and a reinforcing material layer embedded in at least one rubber mixture. The belt is made of a material that is selected from the group of steel, aramid, carbon fiber, natural fiber, magnesium, and magnesium compounds. The reinforcing material layer is a single-ply or multiple-ply layer that is oriented at an angle between 0 degrees and 5 degrees to the circumferential direction, and is made of at least one polyester thread and/or polyester cord.
