Tires

I know tires can be recycled but any place I've ever taken them wants to charge me for taking them. Luckily I used to work at a tire shop so I still have an in with the owner that allows me to drop a few off at no charge. My question is has anyone ever found a way to recycle these and make money, not lose it? If I could find someone to pay a little bit I'd start picking them up off the side of the road. There's so many tire dump sites around here it's not funny.

And no I'm not going to burn them and try to recover the belts...that's just nonsense!
