8.2 Tyre maintenance and pressures

8.2.1 Tyre pressure

CAUTION!
If pneumatic tyres are fitted to your wheelchair it is important
to regularly check the air pressure and for signs of wear.
The maximum tyre pressures are listed in Section 8.3, if in
doubt check the markings on the side of the wheelchair tyre
for guidance.
NOTE: It is important that drive wheels are inflated to equal
pressures as a pair, and likewise the rear. The inflator pump
provides the safest method of inflating your wheelchair tyres
and the pressure can be checked with a standard motor
vehicle pressure gauge.
DANGER!
• Do not inflate beyond the maximum allowed tyre pressure.

8.2.2 Tyre wear

When inspecting the tyres for signs of wear, look for significant
scuff marks, cuts and a diminished tyre tread. Tyres will
need to be changed when the tread cannot be seen over the
complete surface of the tyre, (Fig.8.1).
