http://www.judoamerica.com/helpforclubs/springmat/ is a good example of a car tired based flooring system. I've know people who have used truck springs. And I've even seen the big air bags used for heavy truck suspension that was plumbed together so that the floor could be adjusted for ambient air pressure changes or days when you need more 'bounce'.
