Mounting the inner tube
Watch our video before you start.Pre-inflate the inner tube slightly to avoid pinching.Insert the valve, making sure you are using the correct valve for your rim.Put the inner tube entirely inside the tyre so that it fits inside the rim.Take care not to pinch the inner tube when fitting.
Mounting the tyre

Inflating the tyre
Inflate your tyre carefully, to the pressure recommended by the manufacturer (visible on the tyre sidewall in PSI or bars, 1 bar = 14.51 PSI).Regularly check that your tyre is in the correct position as you inflate it.
