Tire Inspection and Rotation
Front and rear tires perform different jobs and can
wear differently depending on the type of roads driven,
individual driving habits, etc. To obtain maximum tire
life, inspect tires for wear and damage at intervals
shown in the Maintenance SChedule. If general tread
wear indicates only
'A6"
between any two adjacent
tread ribs, replace the tire. Look for abnormal wear
". patterns such as cupping or feathering of the tread
or rapid wear on either the inside or outside of the
tread sUrface:'lf these conditions exist, an inflation,
bearing adjustment or alignment problem is evident.
Refer repairs to an authorized Fleetwood Service
Center. Replace the tire if cuts, bulges, peeling tread
or other signs of damage or failure are evident.
Remove stones and other objects lodged in the tread.
Be certain to cbeck wheel nut tightness (using a torque
wrench) and to adjust the tire pressures, front and
rear, after rotation to agree with the recommended
pressures. Recheck the torque at 100 and 1,000 miles
of operation after wheel installation and once every
6,000 ,miles thereafter.
The outer tire on a dual wheel will skid or drag on
a turn because of the difference in the turning radii
of the inner and outer tires. This results in faster wear
of the outer tire. In general, position the tire with the
largest diameter or least wear at the outside of each
dual wheel. In addition, when vehicles are operated
continuously on high crown roads an increase in air
pressure of from 5 to 10 PSI in the outSide tire of each
dual produces maximum tire life.
Due to their design, radial tires tend to wear faster
in the shoulder area particularly in the front positions.
This makes regular rotation especially necessary. Con-
sult your dealer for proper tire rotation procedures.
With dual wheel installations, measure the cir-
cumference of each tire that is to be installed on the
rear axle with a steel tape. If all tires do not measure
the same, install the two larger tires on one side and
the two smaller tires on the opposite side.
Inflation Pressure
Tires must be inflat'ed to the maximum cold infla-
,tion pressures for the tires when the GVWR or an axle
GAWR is reached. Improper tire inflation pressures for
the' load the vehicle is.carrying c!'l'n adversely affect
~ire
life and vehicle performance. The most common
cause of 'tire' failure is iniproper inflatiOn. '

" Too.lowan air pressure can result in tire'overloading,
abnormal tire wear, adverse vehicle handling, and
. reduced fuel economy. The,tire flexes more and can
build up excessive heat; weakening the tire and in-
creasing susceptibility to damage or fsiiine. Too high
an air pressure can result in abnormal wear, harsh'
v~hicle
ride, and increased susceptibility to d,amage
from road hazards. Lower inflation pressures should
be used only with reduced vehicle loads and the rear
tire pressure should be equal to or greater than the
front pressure on single wheel application. After deter-
mining the load on each tire by weighing the vehicle
on a scale, the correct cold inflation pressures for the
actual tire loads can be obtained from the Tire/Wheel
Load and Inflation Pressure Charts shown. Refer to
the Owner's and Driver's Manual for additional infor-
mation on inflation pressure. Keep an accurate tire
gauge in your tool kit. Check tire pressures cold. DO
NOT BLEED AIR OUT OF WARM TIRES.
Wheel and Tire Balancing
From the standpoints of tire wear and vehicle ride
and handling ease, maintain proper balance of wheel
and tire assemblies. The two types of balancing
systems in current use balance wheels either on or
off the vehicle. The "on the vehicle" type, however,
is the more desirable in that all rolling components
(brake drums, bearings, seals, etc.) are included in the
balancing procedure and thereby have any existing un-
balance corrected. Because of the speCialized equip-
ment required, wheel and tire balancing should be per-
formed by a qualified service shop.
Tire Replacement
When replacing tires, be sure to consult your
Owner's and Driver's Manual for information regard-
ing the proper tire selection. Use of the incorrllct size
or type tire may affect load carrying capacity, ride,
handling, speedometer/odometer calibration, vehicle
ground clearance, and tire clearance to the body and
chassis, If replacing only a single tire, it should be
paired on the same axle with the least worn tire of
the others.
WARNING: DO NOT MIX DIFFERENT TYPES OF
TIRES ON THE SAME VEHICLE SUCH AS RADIAL,
BIAS. AND BIAS-BELTED TIRES EXCEPT IN
EMERGENCIES. BECAUSE VEHICLE HANDLING
AND TIRE LIFE MAY BE SERIOUSLY AFFECTED
AND MAY RESULT IN LOSS OF CONTROL OR TIRE'
FAILURE ..... ,'

five to nine bolt wheels. replace all stud bolts; When
one'stud bolt is ,broken on an axle using ten bolt
wheels, tepla'ce the' broken bolt, plus ttle adjacent bolt '
oli each side. The additional stress placed on the bolts
adjacent to the br()ken bolf weakens them and is the
reason for replacement.
