Tires are made of rubber.
Rubber on the tires is an electrical insulator. No electricity can be conducted from the ground up through the car because of the tires, otherwise a downed power line in some water, with the metal car - yikes! All would be conductive, except the rubber tires.

If you can't spell tires, you shouldn't be driving.
rubber Rubber is used with many other things to make different tires, depending on what they will do, once on a car.
Car tires are not made from rubber trees any more. Tires and other "rubber" products are produced from synthetic rubber, made from petroleum based polymers. Pre-World War II tires were produce using the sap of rubber trees and through a process called vulcanization (created by Charles Goodyear). The vulcanization process entails heating the sap and adding sulfur, peroxide, or bisphenol to improve elasticity. Modern passenger car tires are made from as many as 20 different types of natural rubber from rubber tress and synthetic rubber which is used in different parts of the tire.
