The invention discloses oil-extended rubber used for automobile tires, belonging to the technical field of rubber for automobile tires. The oil-extended rubber is prepared from the following components in parts by weight: 37-45 parts of styrene-isoprene-butadiene rubber, 45-50 parts of styrene-isoprene rubber, 10-15 parts of aromatic hydrocarbon oil, 12-16 parts of safflower oil, 8-12 parts of silicon dioxide, 5-8 parts of fatty acid sorbitan ester, 1-5 parts of p-octyl phenyl salicylate, 5-8 parts of alkylated diphenylamine, 5-8 parts of ethyl carbamate and 1-5 parts of sodium pyrosulfite. The oil-extended rubber used for automobile tires is prepared by mainly compounding two kinds of conjugated diene rubber and adopting the following auxiliary components: aromatic hydrocarbon oil, safflower oil, silicon dioxide, fatty acid sorbitan ester, p-octyl phenyl salicylate, alkylated diphenylamine, ethyl carbamate and sodium pyrosulfite, so that the wear resistance of the oil-extended rubber can be effectively improved.
