Reassembling the tire and inner tube
Please take note of the running direction of
the tire when installing it.
Prevent foreign bodies from entering the
tire. Ensure that the inner tube does not have any
folds and is not squashed. Ensure that the rim
tape covers all spoke nipples and does not have
any damage.
Place one edge of the rim into the tire.
• Push one side of the tire completely into the
rim.
• Insert the valve through the valve hole in the
rim and put the inner tube into the tire.
• Pull the second side of the tire into the rim with
the balls of your hands.
• Ensure that the inner tube is correctly posi-
tioned.
• In the case of Dunlop or Express Valves: Push
the valve stem into the correct position and
tighten the cap nut.
• Pump the inner tube up a little.
• Check that the tire is properly in place and runs
true, using the control ring on the side of the
tire. Adjust the positioning of the tire with your
hand if it does not quite run true.
• Pump the inner tube up to the recommended
tire pressure.
