There are plastics in the tire, but the exterior bulk of the tire is rubber, which is not plastic.

- verseguru 2y agoBulk no. Tyres are apparently only 19% natural rubber. Slightly more is synthetic, and the rest… well none of it is good ground up on roads then breathed in. I lived for a while next to a moderately busy road. Feck it was filthy even with windows never open. Even my mountain bike tyres now contain graphene which doesn't sound like a good idea for the sake of an unnoticeable improvement, and prob only as a racer. Seems a case of new jargon selling more. So they keep adding new compounds.
