WHEEL AND TIRE BALANCING
To insure successful, accurate balancing, the
following precautions must be observed:
• The wheel and tire must be clean and free
of all foreign matter.
• The tire should be in good condition and
properly mounted using the balance mark
on the tire, if any, or lined up with the
inflation valve.
• Bent wheels that have a runout over 1.6 mm
(Ve-inch) should be replaced.
• Inspect the wheel and tire assembly to
determ ine if an out-of-round condition
exists.
Im portant
A severe out-of-round condition cannot be
" balanced out." A wheel and tire assembly
having an out-of-round condition exceeding 4.7
mm ( /ie-inch) is not suitable for the front of the
3
vehicle. Its use on the rear of the vehicle must be
governed by its general condition and whether
the roundness problem seriously detracts from
overall ride quality.
