Our advice: always check the size marked on the sidewall of the tyre before fitting. When fitting, inflate the inner tube slightly to give it its shape, then check that it is not pinched between the tyre and the rim.

Fitting and maintenance

Before fitting the new inner tube, carefully inspect the inside of the tyre to remove any thorns, stones or particles that could cause another puncture.

Next, place the slightly inflated inner tube into the tyre, gradually seat the second sidewall and check that the inner tube is not pinched. Finally, gradually inflate it to the correct pressure for your tyre and your riding conditions.
