Risk of Disease - Piles of tires are ideal breeding grounds for disease-carrying mosquitos and rodents.
Landscape Blight - Dumped tires degrade the landscape. This leads to declining property values and invites more litter.
Fire Hazards - Stockpiled tires are a fire hazard which produce toxic smoke and pollute land, water, and air.
Clean-up Costs - Improper disposal of tires isn't free. The local government, left with the responsibility of cleanup will be required to increase taxes or divert funding from positive programs and services.
