Coker 882500 18 x 7" Flap Center

18 x 7 Inch Flap Center This is a 18 x 7 inch flap. Tube liners, also known as tube flaps or tube boots, are used to protect tubes from wear, heat, and other irregularities in the rims. Typically used on split rims, two-piece rims or vehicles with wood spoke wheels. These flaps are designed with high quality rubber, made for durability and are available in many sizes. We recommend new tube liners when replacing tires.
