TIRES/WHEELS (Continued)
Fig. 1 Checking Tire/Wheel/Hub Runout
1 - RADIAL RUNOUT
2 - LATERAL RUNOUT
METHOD 2 (RELOCATE TIRE ON WHEEL)
NOTE: Rotating the tire on wheel is particularly
effective when there is runout in both tire and
wheel.
(1) Remove tire from wheel and mount wheel on
service dynamic balance machine.
(2) Check wheel radial runout (Fig. 2) and lateral
runout (Fig. 3).
• STEEL WHEELS: Radial runout 0.031 in., Lat-
eral runout 0.031 in. (maximum)
• ALUMINUM WHEELS: Radial runout 0.020 in.,
Lateral runout 0.025 in. (maximum)
(3) If point of greatest wheel lateral runout is near
original chalk mark, remount tire 180 degrees.
Recheck runout, Refer to match mounting procedure.
STANDARD PROCEDURE
STANDARD PROCEDURE - TIRE ROTATION
Tires on the front and rear axles operate at differ-
ent loads and perform different steering, driving, and
braking functions. For these reasons, the tires wear
at unequal rates. They may also develop irregular
wear patterns. These effects can be reduced by rotat-
ing the tires according to the maintenance schedule
in the Owners Manual. This will improve tread life,
traction and maintain a smooth quiet ride.
The recommended method of tire rotation is (Fig.
4) & (Fig. 5). Other methods can be used, but may
not provide the same tire longevity benefits.
CAUTION: 3500 Dual rear tires have a new tire rota-
tion pattern. This is to accommodate the asymmet-

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
