Beschreibung
Zusammenfassung:	Sulphur vulcanised rubber mixture comprises: (a) 100 pph diene elastomer(s) from natural rubber, synthetic polyisoprene, polybutadiene, acrylonitrile-butadiene and/or butadiene-styrene; (b) 35-100 pph of filler comprising (b1) 12-97% carbon back of average particle size 20-40 nm, dibutyl phthalate (DBP)/cetyl trimethyl ammonium bromide (CTAB) ratio > 1.5, DBP number > 145 ml/100 g, CTAB number 70-100 m /g and CDBP number > 100 mg/100 g and (b2) 3-88% finely divided sillicic acid of BET surface area 145-270 m /g, CTAB number 120-285 m /g and pore vol. 0.7-1.7 m/g; and (c) other additives. Also claimed are tyres made using the above rubber mixture. Preferably the mixture contains at least 60 pph natural rubber and 30-65 pph filler. Alternatively, it contains at least 60 pph diene elastomer from synthetic polyisoprene, polybutadiene, acrylonitrile-butadiene and/or butadiene-styrene and 60-100 pph filler. Preferably the filer comprises 50-80% carbon black and also non-activated silicic acid. The mixture contains bis-3(triethoxy-silylpropy)tetrasulphide (TESPT).
