Wondering about using tires for raised beds?

Does anyone out there have feelings about the use of old tires to contain the soil in my greenhouse garden  beds?  I haven't done much research on the pros and cons of old tires.  I like the idea of driving around and picking up the trash from the side of the road. Free supplies and helping clean the neighborhood feels doubly good.  I like the ease of construction--just lay a few courses of tires and fill with dirt.  I like the idea of circular flower beds in my circular greenhouse.

I guess my concerns are poisoning my plants or poisoning myself.  Is there any danger to recycling old tires to grow vegetables in?
