400 X 5 Inner Tube
Size
To find the correct size inner tube or tyre, you need to look at the size identification numbers on the side of your tyre, they will read something like: 410/350 X 6 or 12½ X 2¼ or 3.00-4 (Sometimes fractions will be shown as decimals so 12½ X 2¼ would be 12.5 X 2.25) this is your tyre size, have a look at our inner tubes or tyres and see if we stock your size, if not don't worry we can get it for you very quickly, just contact us.
Valve
Inner tubes often have bent or offset valves to enable easier access with a pump, you should be careful as in the worst case you could have an inner tube that can't be filled with air. Check out the image of different valve types in the product gallery to see which type yours has, but don't worry if we don't have the same type, the most important thing is that there is space to fit a pump on to the valve, you should be able to see this by what space is around your current valve.
