A new study by researchers from Stockholm University concludes that automobile tires may be a potential previously unknown source of carcinogenic dibenzopyrenes—a type of high molecular weight polycyclic aromatic hydrocarbon (PAH)—to the environment. Automobile tire rubber in general consists of approximately 40?60% 20% mineral oils such as extender oils/ softeners.
