6.5.8.1 Adjusting tyre pressure
It is not possible to offer a general recommended
tyre pressure for a particular pedelec or tyre. The
correct tyre pressure largely depends on the
weight load on the tyres, mainly determined by
body weight and baggage.
Unlike cars, the weight of the vehicle has only a
small impact on the total weight. Moreover, the
personal preferences for low rolling resistance or
a high degree of suspension comfort vary a great
deal. It is important to remember that
• the higher the tyre pressure is, the lower the wear,
rolling resistance and the risk of breakdown are.
• The lower the pressure in the tyre is, the greater
the comfort and grip that the tyre offers is.
In the case of pedelecs used on the road, the rule
is the greater the tyre pressure is, the lower the
tyre rolling resistance is. The risk of breakdown is
also lower when the pressure is high. A
permanently excessively low tyre pressure often
leads to premature wear in the tyre. Cracking in
the side wall is a typical consequence of very low
tyre pressure. Abrasion is also unnecessarily
high.
On the other hand, a tyre can absorb road impacts
more effectively at a low pressure.
As a general rule, wide tyres are operated at a
lower tyre pressure. They provide the option of
exploiting the advantages of the lower tyre
pressure without the serious disadvantages it
causes with regard to wear, rolling resistance and
breakdown protection.
Never exceed or go below the minimum and
maximum pressure limits indicated on the tyre.

Pump the tyre to the recommended tyre
pressure.

Perform a visual check on tyres.
