One comment. Due to most state, county and city ordinates, the burning of old tires must be done in controlled and approved (lisensed?) burners and the emissions cannot reach a given pollution level. In other words, it would probably be a crime with a very large fine per violation. Some places might even issue citations on one each tire burnt. Burning the tires is an interesting idea, but would probably end up causing thousands of dollars in fines regardless of the reason for burning them.
