Wheel Replacement
If you have pneumatic tires and you have a at tire, you can
replace the tube. If your chair is equipped with a solid tire
insert, then you must replace the entire wheel assembly.
Replacement tires, tubes, and wheel assemblies are readily
available through your Quantum Rehab Provider.
The wheels on your power chair should only be serviced
or replaced by a Quantum Rehab Provider or a qualied
technician.
Be sure that the controller’s power is turned o󰀨 and the
power chair is not in freewheel mode before performing
this procedure.
When changing a tire, remove only the ve lug nuts,
then remove the wheel. If any further disassembly is
required, deate the tire completely or it may explode.
Follow these easy steps for a quick and safe repair for
both pneumatic and solid tires:
1. Turn o󰀨 the power to the controller.
2. Set the power chair up on blocks.
3. If you are changing a pneumatic tire, completely deate
it before removing the wheel.
4. Remove the ve (5) lug nuts from the wheel hub. See
gure 13.
5. Pull the wheel o󰀨 of the hub.
6. Remove the screws and separate the front and rear rim.
See gure 14.
7. Remove the old tube from the pneumatic tire and replace
it with a new tube or replace the entire assembly if it is
a solid tire.
8. Screw together the two rim halves.
9. Slide the wheel back onto the hub.
10. Reinstall the ve (5) lug nuts onto the wheel hub and
tighten.

rating indicated on each tire.
