if they are YOUR tires we are allowed to dump 5 tires. Actually dumping them means rolling them inside a trailer. If its more I think it was $2 per tire. The tire stations around here charge $2 per tire if they have to get rid of them. I usually just say toss them in the back. Then go to land fill. Long time ago we use to burn them in a 55 gal drum just outside the "barn" and warm out butts by it.
