Tires are banned from landfills because they are difficult to keep buried in landfills, do not decompose easily and are a breeding spots for mosquitoes. Tires can be disposed of in landfills if they are cut into quarters, shredded or chipped. Most tires are burned as tire derived fuel for electrical generation or ground and used as a playground surface. Many tire dealers will accept old tires but will charge a small disposal fee unless new tires are purchased. You can recycle used tires at Tire Shredders Unlimited in High Ridge, (636) 677-8471.
