  • Pneumatic tire with tread containing plasticizer, plasticizer mixture for pneumatic tire, and method of producing such plasticizer mixture
    Patent number: 5252649
    Abstract: The plasticizer constituent in the rubber mixture of the tread member of a pneumatic vehicle tire contains at least partially at least one fatty acid triglyceride, preferably natural rape seed oil in which more than 50% of the fatty acid residues are present as oleic acid residues and an oleic acid/linoleic acid ratio is greater than or equal to 2:1. Sunflower seed oil or natural rape seed oil and triglyceride of oleic acid also can be used as the fatty acid triglycerides. There is thus achieved improved traction upon ice and snow as well as at dry and wet roads in the absence of negative effects on other properties of the tire.
