6.3 Tyres
To ensure that your wheelchair functions
properly, it essential that the tyres are kept at
the correct pressure. The correct pressure is
indicated on the side of the tyre.

Tyres that are too soft will have a negative
effect on the wheelchair’s performance. Moving
the wheelchair will require more energy, making
more demands on the batteries. Furthermore,
wear on the tyres when driving with soft tyres is
unnecessarily high.
Note!
Never exceed the maximum tyre pressure
