TIRE AND WHEEL
TIRE REMOVAL
The most critical factor of a tubeless tire is the seal between the
wheel rim and the tire bead. For this reason, it is recommended
to use a tire changer that can satisfy this sealing requirement
and can make the operation efficient as well as functional.
For operating procedures, refer to the instructions supplied by
the tire changer manufacturer.
NOTE:
When removing the tire in the case of repair or inspection, mark
the tire with a chalk to indicate the tire position relative to the
valve position.
Even though the tire is refitted to the original position after repair-
ing puncture, the tire may have to be balanced again since such
a repair can cause imbalance.
