The secret to successful installation is to start with a good tutorial.Watch the video, slightly inflate, insert the valve, place the inner tube in the tyre, push it into the rim strip, and avoid pinching.

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.

Start by mounting the tyre onto the wheel on the opposite side to the valve. Finish mounting the tyre at the valve to avoid pinching the inner tube. Never mount your tyre with a screwdriver or a tyre lever, as you risk pinching and puncturing the inner tube.

To take good care of your bike, it\'s important to know the exact dimensions of your tyres,This information is given on the tyre sidewall (diameter and cross-section).For example, 27.5 x 2.00 means a tyre with a 27.5-inch diameter that is 2.00 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-584 means that the tyre is 50 mm wide with a 584 mm internal diameter (approx. 27x2.00).
