Wheel Replacement
If you have pneumatic tires and you have a flat tire, you can replace the tube. If your chair is equipped with a solid
tire insert, then you must replace the whole wheel assembly. Replacement tires, tubes, and wheel assemblies are
readily available through your authorized Pride Provider.
WARNING! The wheels on your power chair should only be serviced or replaced by an authorized
Pride Provider or a qualified technician.
WARNING! Be sure that the power to the controller is turned off and the power chair is not in
freewheel mode before performing this procedure.
WARNING! When changing a tire, remove only the center lug nut and washer, then remove the
wheel. If any further disassembly is required, deflate the tire completely or it may explode.
