Open side circumference check
WARNING Wheels that have been subjected to high pressure tire
and rim separation, run flat, excessive heat or other physical damage
may no longer have sufficient dimension and contour to retain tire bead
while under pressure.
Rims that lack proper dimension and contour can lead to explosive
separation of tire and rim, causing injury or death.
Follow dimension check procedures described in this section during each
wheel inspection.
The circumference of the bead seat on the open side of the wheel should be checked
with each tire change. The open side is the side opposite the disc face. In the case
of center flange wide base wheels, or wheels with insets less than 3 inches, both rim
flanges should be checked. Measure the circumference of the bead seat on the open
side (see illustration below) with a ball tape. Ball tapes used for measuring wheel
circumference can be purchased from the Tire and Rim Association, Inc., 175 Montrose
West Avenue, Copley, Ohio 44321.
If the circumference of the bead seat does not match the required dimension as indicated
by the ball tape, remove the wheel from service. Be sure to clearly mark the wheel as
out-of-service or otherwise render the wheel unusable.
Any wheel known to have been run with a flat tire or operated under abnormal conditions
should be checked before continued service. If a ball tape is unavailable, roll the unmounted
wheel without a tire several revolutions over a smooth, flat, level, clean surface. Any
deviation from rolling in a straight line is an indication of a potential lack of proper
dimension and contour. Remove the wheel from service until it can be properly checked
with a ball tape.
