STEP 2. After the wheel is separated from the tire, use a ball tape to verify the
circumference of the bead seat on the open side is acceptable (see 2-3, page 7).
Check the wheel flange with the Alcoa Rim Flange Wear Gauge to determine
if the wheels must be removed from service for excessive rim flange wear
(photo 1 on page 13).
See Rim Flange Wear Gauge Instructions illustrations above to make this
determination. If you do not have an Alcoa Rim Flange Wear Gauge, contact
Alcoa Wheel and Forged Products to obtain a gauge(s) at no charge.
STEP 3. If the wheel is deemed to be serviceable by the rim flange gauge,
examine the wheel flange edge for sharpness by using a rubber sharpness gauge.
These gauges are constructed by having a section of tire side wall or a suitable
piece of rubber attached to a block of wood (photo 2). By running the sharpness
indicator gauge along the wheel in the area of the wear, determine if the wear is
sharp enough to cut or damage the rubber on the sharpness indicator (photo 3).
If the rubber is cut, then follow the edge removal instructions below.
If the flange cuts or appears close to being sharp enough to cut the rubber on
the sharpness indicator gauge, the edge can be removed per the edge removal
procedures below. If the rubber is not cut, then the wheel can be returned
to service without further work for rim flange wear.

along the wheel in the area of the wear to
determine if the wear is sharp enough to cut
or damage the rubber on the sharpness
indicator.
NOTICE: Examine the tire
for cuts in the bead area
and side wall. If no damage
occurred to these areas,
return the tire to service.
Cut tires should be removed
from service. The tire should
be inspected at this time
for any other damage and
be treated per normal tire
procedures recommended
by the tire manufacturer.
NOTICE: Check the wheel
at every tire change or
ONCE PER YEAR for rim
flange wear and any sharp
edges. If you follow this
practice, you will significantly
reduce the possibility of a rim
flange cutting into the tire.
CAUTION Do not run unprotected hands or fingers across worn rim flange
areas of used wheels.
Worn rim flange areas are sharp and can cut hands or fingers.
Cuts can lead to infection.
Always wear gloves when handling used wheels or when testing
for edge sharpness.
