We accept both oversized tires and tires with rims. Oversized tires are placed in a pile to be periodically sheared by a hydraulic excavator into pieces small enough to be fed into the shredder. Tires with rims are placed in a pile to have the rims removed with an excavator-mounted shear. Once removed, the rims are recycled as scrap metal while the de-rimmed tires are fed into the shredder.
