Abstract:
The invention relates to a rubber mixture, in particular for pneumatic vehicle tires, bands, and belts. The rubber mixture is characterized by the following composition: at least one diene rubber and—at least one precipitated silicic acid having a CTAB surface area greater than or equal to 150 m2/g and a BET surface area greater than or equal to 150 m2/g and a DBP number between 180 and 350 g/100 g and a full width at half maximum, which is standardized to the location of the reflection, of the reflection of less than or equal to 0.95 and a homogeneity ratio d 25% to d 75% of 1.00 to 1.80 and a relative width Ypressed in the compressed state of less than or equal to 2.8 (g nm)/ml and a fineness index F.V.pressed in the compressed state between 100 and 140, and further additives.
