Wheels and tyres
The assembly consisting of the hub, spokes, tube
protector and wheel rim is referred to as the wheel.
The tyre is mounted on the rim and pressurised with
a tube. To protect the tube against the sharp edges
of the rim base or spoke nipples, it is lined with a tube
protector.
After the first hours of use, the spokes and nipples
may settle. Check the run-out of your wheels. If your
wheels exhibit run-out, have them inspected or, if
applicable, centred by a bike specialist or contact
an authorised Porsche Centre or the Porsche Bike
hotline.
If a tyre change is necessary, use original spare
parts or tyres of exactly the same size. The size of
your tyre is specified on the tyre sidewall, either in
standard millimetres [ e.g. 52–622; 52 mm width
when inflated and 622 mm [ inner ] diameter ] or in
inches [ e.g. 28 x 2.0 ].
Sudden restriction of the turning angle. Using
tyres that are larger than the factory recommended
size may result in contact between your foot and the
front wheel when turning. There is a risk of crashing.
Only mount tyres that correspond to the factory
recommended size.
Overload due to incorrect tyre size. Using tyres
that do not correspond to the factory recommended
size may overload the frame and front fork. There
is a risk of fracturing. Only mount wheels with the
corresponding factory recommended size.
Tyres that are larger than the factory recom-
mended size may rub against the frame and front
fork and damage the paint.
Only mount wheels with
the correct factory recommended size.
PLEASE NOTE
WARNING
WARNING
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.
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.
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 is fitted with presta valves.
PLEASE NOTE

Reduced tyre grip. Tyres with a worn profile lose
their grip. Replace worn tyres.
