How would a chemist test for petroleum products in tires?

This is an example problem. I am in Organic Chemistry I, so the answer needs to have something to do with isolating something. I’m just not sure what. Please Help!

    Petroleum (L. petroleum, from Greek: petra (rock) + Latin: oleum (oil)[1]) or crude oil is a naturally occurring, flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth’s surface. Petroleum is recovered mostly through oil drilling. It is refined and separated, most easily by boiling point, into a large number of consumer products, from gasoline and kerosene to asphalt and chemical reagents used to make plastics and pharmaceuticals

    There is very little on the internet, most are commercial sites which offer very little in the way of info.
