Checking the tyre pressure
There are essentially three different types of bike tyre valve (see figure below):
The permissible tyre inflation pressure is indicated on the side of the tyre. A pressure
range is given. Test which tyre inflation pressure is best for you. We recommend a bicycle
stand pump with pressure gauge for checking and correcting the tyre inflation pressure.
Note for Presta valve:
- Loosen the union nut by one to two turns.
- Press the valve end briefly in the direction of the wheel rim. If there is air in the tyre, it will
escape audibly.
- Screw the union nut tight again after inflating.
Proceed as follows to check the tyre pressure:
- Unscrew the valve cap from the bike valve.
- If necessary, follow the specific instructions for the Presta valve.
- Attach the connection of the stand pump intended for the valve type to the bike valve.
The pressure gauge shows the current tyre inflation pressure.
- Correct an incorrect tyre inflation pressure.
- Finally remove the connection of the stand pump from the bike valve.
- Screw the valve cap onto the bike valve.
