Fitting a tyre:
For safe installation, start at the valve and work your way to the opposite end.Never use metal tools that could pinch the inner tube.
How to choose an inner tube:
To maintain a bike, it's essential to know the exact dimensions of the tyres.This information is found on the sidewall of the tyre (diameter and width).For example, 16 x 1.60 corresponds to a tyre that is 16 inches in diameter and 1.60 inches wide.
The ETRTO marking (e.g.40-305) indicates a width of 40 mm and an inner diameter of 305 mm, which is equivalent to 16 x 1.60.
Inflating a tyre:
Observe the pressure indicated on the sidewall of the tyre.Ensure that the tyre remains securely in place during inflation.

To remove your inner tube, the tools you'll need are:
Remove the worn inner tube using B’TWIN tyre levers.
Checks to carry out before installing an inner tube:
Remove any grit, glass or debris stuck in the tyre.
A foreign object left behind can cause a puncture very soon,so check the tyre thoroughly.
Check that no objects are stuck in the rubber after a ride.
Even a small stone can puncture your inner tube over time.Clean the surface of the tyre before refitting it.
Run your finger gently over the tyre to feel for any abnormalities.
Pro advice:
Before setting off, check your tyre pressure:properly inflated tyres prevent punctures and improve performance.
