CHAPTER THREE
Inspection, Adjustment & Lubrication
A tubeless tire must be complete sealed to the rim
Before a tubeless tire can be inflated, both beads
must make full contact with the rim strip at the
bottom of the rim well, all the way around the
rim. For this to happen, a tubeless tire must fit
more tightly on the rim than a conventional tire.
With a snug fitting tubeless tire, bare-handed
installation may be difficult. If you use tire levers
for installation or removal, avoid damaging the
rim or abrading the tire beads. If either surface
is roughened, air may bleed excessively from the
mounted tire.
If the tire beads are sealed on the rim strip,
air pressure will push the beads up to the rim
hooks, where they can seal tightly. You don't need
a compressor to do this; a good floor pump or an
air cartridge will work. Even a hand pump may
work, if nothing else is available.
To install a valve stem
1. Center the tubeless rim strip in the rim, and
align the valve holes of the rim strip and rim.
2. Align the slot on the head of the tubeless valve
with the rim (Figure 3.10.1), and press the
valve stem through the rim strip and the rim.
3. Thread the tubeless valve nut (Figure 3.10.1)
onto the valve, and tighten firmly by hand.
There should be no gap between the valve and
the rim strip.
4. Make sure the rim strip is smooth, even, and centered in the
rim well.
To install a tubeless tire.
It is recommended to lube the tire and rim with soapy water
to aid in tire installation and seating of the bead.
1. Starting opposite the valve, lay one tire bead into the center
of the rim well.
Note: If you start at the valve, the bead will lie on top of the valve, which
will take up some slack needed to lift the tire bead over the rim shoulder
(Figure 3.10.2).
2. Start opposite the valve again, and install the second tire
bead until there is about 10 inches (25cm) of bead left
outside the rim.
