Tires made of rubber insulate passengers from rough road surface, are relative light weight, maintain their shape when inflated, most punctures are easily reparable, can be made with tread patterns to allow control by the driver in inclement weather conditions and increase braking power.
Tires made of iron are heavy, expensive, will get dents and bruises in rough road conditions which are hard to repair, transfer road irregularities to passengers, can generate electrical sparks when scrqaping along the road when braking.

it is made of polymer
Car tires are made up of a combination of elements, including rubber, carbon black, and various chemical additives. The main component of tires is rubber, which is a polymer made from molecules containing mostly carbon and hydrogen atoms. These elements provide tires with their elasticity, durability, and grip on the road.
A burn out will ruin tires on race cars by burning up the rubber. The rubber of the tires will get worn from the friction of the pavement causing the tires to tear.
Rubber tires are preferred to steel tires because if we had steel tires driving over the smallest pebble would be a very bumpy ride. Rubber tires are flexible and will be smooth when going over rocks. Not to mention, if we had steel tires the government would have to replace the roads everyday with the amount of people tearing them up with steel tires. Also, rubber tires wear out and that means you will have to buy new ones again..

Retreaded tires are refurbished tires. Instead of winding up in a landfill, they are recoated with rubber and resold. They are safe and cheaper than new tires.
Rubber.
Over uneven ground, a cart with solid tyres does not give, when faced with a small object. When you pull it, the tyre will have to rise up and lift the cart over the object. This lifting requires more effort to raise the cart. A rubber tyre will give a little and allow small objects to press into the tyre, without lifting it. Small bumps are averaged out and allow the cart to continue without being lifted, requiring extra force.
There is one type of metal in a car tire. There are steel bands that are made of iron. These bands are near the edge of the tire that make up what is called the "bead." The bead is the part of the tire that fits around the rim.
Footballs are now made up of natural rubber bladder. Rubber bladder are made up of Butyl Rubber, 100% pure Butyl Rubber is preferred.
The tires of an airplane are made of conducting rubber to help dissipate static electricity that can build up during flight, particularly during takeoff and landing. This helps prevent sparks that could potentially ignite fuel vapors. Conductive rubber tires also help to provide better traction and reduce wear and tear on the runway surface.
