Push edge of cover, that is diametrically opposite to the valve, RIGHT INT O WEL L
OF RIM and, using tyre lever 017007, pick up edge of cover NEAR VALVE so
that it comes off over the edge of the rim.
Work off the remaining edge of the cover till it is clear of the rim. This is quite easy
and there is no reason to use force.
Push upwards valve stem through its hole in the rim, and the inner tube is then free
to be taken away.
Remove cover from rim by pushing it right into well of rim and, diametrically opposite,
picking it up with the tyre lever and then working it off all the way round.
TYRE FITTING
Re-fit inner tube and outer cover by :
Place one edge of cover right into well of rim, with the three white dots on the cover side
adjacent to the valve hole, and, commencing diametrically opposite, and using the
hands only, work the cover over the edge of the rim.
Replace the valve " inside " and slightly inflate the inner tube. (Do not distend the tube.)
Fit the valve into its hole in the rim and replace its nut, only screwing It on the valve
stem about half an inch.
Tuck in the inner tube so that it lies snugly in the cover. Ensure it is not twisted.
Smear some soapy water round the free edge of the cover. This is a great help in fitting
and in ensuring the cover centralises itself on the rim and should always be employed
if at all possible.
Introduce the free edge of the cover into the rim at the spot diametrically opposite to
the valve. Get this edge right into the well of the rim and then, by working round the
cover, equally on either side of the valve position, the cover will slip into place without
excessive exertion, fitting the part nearest to the valve last of all.
Slightly Inflate the inner tube and inspect for the inner tube being trapped between the
outside edge of the cover and the rim at the spots where the valve is located.
Half inflate tyre, spirt wheel and test for trueness because it is essential the pattern of the
tread runs evenly and the cover must be manipulated till that occurs. This
centralisa-
tion of the cover is most important.
Inflate to required pressure.
Screw fully home the nut on the valve.
Replace the valve cap.

The best method of ascertaining the correct pressure is to actually weigh the loads on
the front and rear tyres. This should be done on a weighbridge and is a service that
can usually be provided by British Railways at a Goods Depot or by a Corporation at
Its Depot.
When the weights are known the table above can then be used.
As a rough guide it may be stated that, with a rider of average weight and with normal
equipment, solo, the pressure should be 18 lb. for the front tyre and 22 lb. for the rear.
