Tyres for vehicles are made from polymerization products of diolefine mixtures containing 2-3 dimethyl butadiene together with butadiene and/or isoprene, finely divided soot being added before vulcanization. Other organic plastic masses and softening agents may be added. In an example, 100 parts of a polymerization product from equal parts of 2-3 dimethyl butadiene and butadiene emulsified with for instance sodium stearate, are mixed with 50 parts carbon black, 15 parts zinc white, 2 parts stearic acid, 4 parts tar, 1 part sulphur, and 0,8 part of the decahydroquinaldine salt of decahydroquinaldyl dithiocarbamic acid (obtained by reacting 2 molecular proportions of decahydroquinaldine with 1 molecular proportion of carbon disulphide at normal temperature). A tyre profile is made by pressing, calendering, or spraying, combined with a carcass, pressed in a mould and vulcanized at 140 DEG C. Specifications 23648/12, [Class 2 (iii), Dyes &c.], and 326,202, [Class 70, Indiarubber &c.] are referred to.ALSO:Tyres for vehicles are made from polymerization products of diolefine mixtures containing 2,3 dimethyl butadiene together with butadiene and/or isoprene, finely divided soot being added before vulcanization.
