What are Tires Made of?

There's this new thing that's a tangle of tubes and wires called the internets. Sometimes people leave bits of stuff in it. Like this:

Great Idea, I have read mot of the study's that relate to tires, where is the chemical, data. Do you know you ? Natural rubber, or polyisoprene is the basic elastomer used in tire making Styrene-butadiene co-polymer (SBR) is a synthetic rubber which is often substituted in part for natural rubber based on the comparative raw materials cost Polybutadiene is used in combination with other rubbers because of its low heat-buildup properties Halobutyl rubber is used for the tubeless inner liner compounds, because of its low air permeability. The halogen atoms provide a bond with the carcass compounds which are mainly natural rubber. Bromobutyl is superior to chlorobutyl, but is more expensive Carbon Black, forms a high percentage of the rubber compound. This gives reinforcement and abrasion resistance Silica, used together with carbon black in high performance tires, as a low heat build up reinforcement Sulphur crosslinks the rubber molecules in the vulcanization process Vulcanizing Accelerators are complex organic compounds that speed up the vulcanization Activators assist the vulcanization. The main one is zinc oxide Antioxidants and antiozonants prevent sidewall cracking due to the action of sunlight and ozone Textile fabric reinforces the carcass of the tir

We consider it bad form to not credit the work of others.

Does this answer your question? You asked "...where is the chemical, data." How about sulphur, carbon black, silica, zinc oxide... these are all included in the Wiki article. Do you wish for the formulation?
