This fits a wheel rim with a diameter (distance across the middle of the wheel) of 8" and a wheel width of 4". Butyl is stronger and very high quality.
 
Our innertubes come in a range of sizes which can fit anything from pushchairs to wheelbarrows. Buyers will receive one complete inner tube with valve as pictured. The best way to work out which size you need is to look at your tyre (size is written on one the sides of the tyre).
