NOTE: Before installing tire on inner rim half, inspect tire
sidewalls for a "paint dot." Paint dots are often used to indicate
the tire's light spot for balancing purposes. If paint dot is
present, position tire on rim halves so that paint dot is aligned
with insert hole on outer rim half.
NOTE: The Wrangler GS-A, 37 X 12.50R16.5 LTD touring
radial tire has a directional tire tread. The heavier, stiffer tread
on the outside shoulder of tire must face outward when being
installed. Before installing, inspect sidewall of tire and ensure
SIDE FACING OUTWARDS imprint is facing outward
(Figure 6-11).

half. Check to ensure O-ring seal has not been disturbed
