21 x 5 Inch Flap




This is a 21 x 5 inch flap. Increase the service life of your inner tube with a new tube liner. 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. Speak to a Tire Expert for assistance with your order.
