Tires
6.5.8
It is not possible to offer a general
recommended tire pressure for a particular ebike
or tire. The correct tire pressure largely depends
on the weight load on the tires, 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 tire pressure is, the lower the wear,
•
rolling resistance and the risk of breakdown are.
The lower the pressure in the tire is, the greater
•
the comfort and grip that the tire offers is.
In the case of ebikes used on the road, the rule is
the greater the tire pressure is, the lower the tire
rolling resistance is. The risk of breakdown is
also lower when the pressure is high.
A permanently excessively low tire pressure often
leads to premature wear in the tire. Cracking in
the side wall is a typical consequence of very low
tire pressure. Abrasion is also unnecessarily
high.
On the other hand, a tire can absorb road impacts
more effectively at a low pressure.
As a general rule, wide tires are operated at a
lower tire pressure. They provide the
advantages of the lower tire pressure without
the serious disadvantages it causes with regard
to wear, rolling resistance and flat protection.
Never exceed or go below the minimum and
maximum pressure limits indicated on the tire.

pressure.
