- haltist 3y agoA car tire is not purely rubber, it is combined with synthetic polymers derived from petroleum and petroleum derivatives (same as plastics).
- emptybits 3y agoCar and light truck tires are apparently only about 19% rubber.[1] More than half of a tire's composition is synthetic polymers, fillers, and textiles (e.g. polyester, rayon, nylon).

But eliminating car exhaust apparently isn't the big car pollution problem.

- I_Am_Nous 3y ago>Tire factories start with bulk raw materials such as synthetic rubber (60% -70% of total rubber in the tire industry[2][3]), carbon black, and chemicals and produce numerous specialized components that are assembled and cured. Looks like most of the rubber used these days is synthetic[1], usually made of styrene and butadiene which could easily degrade into base monomers or at least shorter chains. 1. https://en.m.wikipedia.org/wiki/Tire_manufacturing https://en.m.wikipedia.org/wiki/Tire_manufacturing
