Set two of the widest weighted balance patches available side-by-side on
the tread directly above where the left and right weighted patches will be
installed inside of the tire. The patches should be positioned as far apart
from each other as possible, but should not be placed in the sidewall or
shoulder area of the tire.
Mark the tire tread at the center of the patches for future placement
reference and remove the patches from the wheel.
