12. Wheels & Tyres
The smaller powerchairs will be fitted with one-piece plastic rims and
solid tyres, the larger powerchairs have split aluminium rims and
either pneumatic or infill tyres. Whenever replacing tyres or inner
tubes it is essential that the tyres are completely deflated before
attempting any replacement.
Above is the breakdown of a typical wheel assembly which consists
of an inner and outer rim; these are held together by four bolts.
The wheel is mounted using a central 8mm bolt which should be
tightened to 15Nm torque. Always use a thread locking compound
to the specification previously mentioned when re-assembling the
wheel and on the main axle bolts when re-fitting the wheel to the
powerchair.
The chart below shows the manufacturers recommended tyre
pressure for different sized wheels. Tyre pressure may be reduced by
3 psi. to give a smoother ride over small bumps.
