Remember that in order to preserve the interchangeability of wheels on wheelchairs fitted with quick release wheels, both tyres must be inflated to the same pressure.

Whenever a tyre is flat, it may be necessary to remove the tyre from its rim. (photo 10)

Force the air out the the inner tube by pressing valve A.

Stretch the outer case on the rim. Repair or replace the inner tube. Put the inner tube back in place. Reposition the outer case on the rim. Re-inflate the tyre to specified pressure.

Note : It may be necessary to use one or two tyre-levers (Not supplied).
