Use

This 2-pack of 18-inch inner tubes is made primarily for kids’ bikes and small everyday bikes. They also fit compact 18-inch bikes as well as small trailers or light carts equipped with this wheel size. These tubes are intended for standard clincher tires (tires with inner tubes) and can also be used inside a tubeless-ready tire as long as the tire is compatible with a tube.
