I had a customer that collected and shipped old auto and truck tires to china. They would freeze them with liquid nitrogen (or something to that effect) and then pulverize the rubber to little pieces. They told me the steel inside the tire would come out looking brand new and be recycled while the rubber was used in power generation facilities since it contained more BTU's per lb than coal.

I don't know if that would work with press on tires with the steel band being so thick but it is an avenue not discussed above.
