STANDARD PROCEDURE - TIRE ROTATION
Tires on the front and rear a xles operate at differ-
ent loa ds an d perform differen t st eering, drivin g, an d
brakin g fun ctions. For th ese rea son s, th e tires wear
at u nequal rat es. They ma y also develop irregular
wear pat terns. These effect s can be reduced by rot at-
ing the t ires according to the mainten ance schedule
in the Owner s Ma nua l. Th is will improve t read life,
traction an d m ain tain a sm ooth quiet ride.
The recomm ended method of t ire rotation is (F ig.
9) & (Fig. 10). Other met hods can be used, bu t may
not provide th e same tire longevity benefits.
CAUTION: 3500 Dual rear tires have a new tire rota-
tion pattern. This is to accommodate the asymmet-
rical design of the ON/OFF road tires and the use of
the outlined white letter (OWL) tires. When replac-
ing a flat, the spare tire may have to be remounted
on the rim or installed at a different location to
maintain the correct placement of the asymmetrical
design or the (OWL).
