Installing the 90 Degree Valve Stem Tube


Although the 90 degree valve stem will simplify adding air
and checking pressure, it does require a bit of work to in-
stall due to the narrowness of the Currie rims.

Begin by opening the valve stem hole slightly with a file. 
You will need to increase the diameter until it reaches the
inner vertical wall of the rim. (about 3/8") Smooth off all
rough edges!! 


***Note: You should always add a rim liner or rubber tape
around the rim to cover the spoke nipples that protrude and 
may puncture the tube.

Using tire levers or a blunt set of screwdrivers, install the 
lower half of the tire over the rim. Blow up the tube till it
takes on a "full" shape, but NO BIGGER! The air in the 
tube will prevent "folds" or pinching during installation.
Carefully tuck the tube into the tire, paying attention to
the location of the valve and valve hole.

NOTE: Be sure to position the valve to point in the 
proper direction when installed! (toward the brake
side of the wheel assembly)

Feed the valve stem into the hole in the rim till it just
protrudes beyond the rim. (above) Install the valve cap.

The valve stem must be left in this position till the tire is
installed. Otherwise, the portion of the stem inside the rim
will prevent the tire bead from properly seating.

Using the tire levers or screwdrivers, carefully install the
top bead of the tire under the lip of the rim. Once the tire
is installed, and BEFORE adding air or pulling the valve
into position, be certain that the tire bead is fully seated
on the rim. There are thin, circular, embossed lines on 
most tires that are used as checks, or gauges to 
determine if the tire and rim are concentric. Check BOTH
sides of the tire fully. When the embossed circles and the 
rim are concentric, pull the valve stem up into position. 
You may need to use a pair of pliers, so grab the plastic
cap to avoid damaging the threads on the valve.


When the valve is in position, remove the cap and add
just enough air to shape up the tire. Don't blow the tire
up fully yet, since you may need to go back and adjust 
the tire to run true on the rim. If necessary, release air
and readjust the tire on the rim till it's concentric!


When the tire is properly adjusted, add enough air to
bring the pressure to about 40 psi. (for most tires and
general use)
