Wheels and tyres
Mounting the wheels
The wheels are mounted in the frame and front forks
by means of the quick releases or nuts [ rear wheel of
the Bike S ].
The chapter “Handling the quick releases” on p. 23
describes how to mount your wheels without tools.
If your wheel must be mounted with nuts [ Bike S ],
then use the designated tool for this [ open-end wrench
SW 15 ]. Tighten the nuts by applying 30–45 Nm.
With gear hubs, you should also make sure that the
hub’s non-turn washers have been properly mounted.
Consult the owner’s manual of the hub manufacturer
for specific details on types and configurations.
The air pressure of your tyres determines the risk of
flat tyres [ e.g. insufficient air pressure when riding
over a curb ], but also rolling friction, wheel grip and
suspension comfort. The air pressure recommended
by the manufacturer is generally located on the tyre
side wall or the type label.
Reduced tyre grip.
Tyres with a worn profile lose
their grip. Replace worn tyres.
Sunlight and the elements.
Tyres may become
brittle and crack. There is a risk of crashing. Replace
cracked tyres.
Sudden loss of tyre pressure.
Excessive tyre
pressure may cause the tyre to pop or slip off the
rim. There is a risk of crashing. Always cycle with
the prescribed tyre pressure.
Loose wheels.
A loose wheel may cause a crash or
accident. Check whether the wheels are secure every
time before using the bike.
Sharp and pointy irregularities or obstacles pose
a risk of damage to the tyre.
Check the condition of
the tyres on a regular basis.
Always cycle with the prescribed tyre pressure and
check it weekly. Observe the maximum permissible
tyre pressures indicated on the rims. You can also
obtain them from the documentation provided by the
rim manufacturer.

WARNING
Normally, 3 types of valves are used to fill and seal the
tubes.
– The Sclaverand valve or presta valve is used with
almost all bike classes and is designed for maxi-
mum pressures. The knurled screw must be loos-
ened in order to fill or release air. After filling, make
sure that the knurled screw is tightened to prevent
air from escaping.
– The Schrader valve or auto valve is adopted from
automobiles and mainly used with mountain bikes.
– The Dunlop valve or blitz valve is the classic valve
used for bikes.
A plastic cap on the valve prevents dirt from entering
the valve.
Your Porsche Bike RS and Porsche Bike S have presta
valves.
