Abstract

The rubber mixtures according to the invention, containing at least one rubber, a filler, optionally additional rubber auxiliaries and at least one polysulphide polyether silane corresponding to the formula EQU R.sup.1 R.sup.2 R.sup.3 Si--X.sup.1 --(--S.sub.x --polyether --).sub.m --(--S.sub.x --X.sup.2 --SiR.sup.1 R.sup.2 R.sup.3).sub.n (I), are used for the preparation of rubber vulcanisates, from which in particular tires having a low rolling resistance associated with a good wet skid resistance and a high abrasion resistance can be produced.
