This is a truck tire ( 20 " ) that wood has been added to the top for an elevated sleeping platform and play area. When cleaning the stall the tire is merely rolled out.
Old wooden wire spools ( can usually be obtained for free ) are used for elevated areas as well. Notice that a couple of boards were removed from the center. This makes and excellant place for kids to hide and feel secure. Double-decker tires are also pictured, making various heights possible.
