Go to the city of Pittsburgh website: pittsburghpa.gov. Go to the section on recycling, or search "recycle tires." The city has 3 recycling drop off centres. All 3 will take tires A maximum of 2 tires per day can be dropped off at any one of those drop off centers.. I know one is in the strip district by the 31st street bridge.
Anybody that sells tires in Pennsylvania will take a used tire for the fee mandated by the state.
