3F-4 WHEELS AND TIRES
Dynamic balance, as shown in left figure, is the equal distribution
of weight on each side of the wheel centerline so that when the
tire spins there is no tendency for the assembly to move from side
to side. Wheels that are dynamically unbalanced may cause
shimmy.
GENERAL BALANCE PROCEDURES
Deposits of mud, etc. must be cleaned from inside of rim.
Each tire should be inspected for any damage, then balanced according to equipment manufacturer’s recom-
mendation.
OFF-VEHICLE BALANCING
Most electronic off-vehicle balancers are more accurate than the on-vehicle spin balancers. They are easy to
use and give a dynamic (two plane) balance. Although they do not correct for drum or disc unbalance as does
on-vehicle spin balancing, this is overcome by their accuracy, usually to within 1/8 ounce.
ON-VEHICLE BALANCING
On-vehicle balancing methods vary with equipment and tool manufacturers. Be sure to follow each manufac-
turer’s instructions during balancing operation.
1. Heavy spot wheel shimmy [C] : Before correction
2. Balance weights addition point [D] : Corrective weights
3. C/L of spindle
WARNING:
Stones should be removed from the tread in order to avoid operator injury during spin balancing and
to obtain good balance.
WARNING:
Wheel spin should be limited to 35 mph (55 km/h) as indicated on speedometer.
This limit is necessary because speedometer only indicates one-half of actual wheel speed when one
drive wheel is spinning and the other drive wheel is stopped.
Unless care is taken in limiting drive wheel spin, spinning wheel can reach excessive speeds. This
can result in possible tire disintegration or differential failure, which could cause serious personal
injury or extensive vehicle damage.
CAUTION:
For vehicle equipped with ABS, using on-vehicle balancing method with ignition switch ON may set
malfunction diagnostic trouble code (DTC) of ABS even when system is in good condition.
Never turn ignition switch ON while spinning wheel.

MAINTENANCE AND MINOR ADJUSTMENTS
WHEEL MAINTENANCE
Wheel repairs that use welding, heating, or peening are not approved. All damaged wheels should be replaced.
WHEEL ATTACHING STUDS
If a broken stud is found, see Section 3E (rear) or Section 3D (front) for Note and Replacement procedure.
MATCHED TIRES AND WHEELS
Tires and wheels are match mounted at the assembly plant.
This means that the radially stiffest part of the tire, or “high spot”,
is matched to the smallest radius or “low spot” of the wheel.
This is done to provide the smoothest possible ride.
The “high spot” of the tire is originally marked by paint dot (1) on
the outboard sidewall. This paint dot will eventually wash off the
tire.
The “ow spot” of the wheel is originally marked by paint dot (2) on
the wheel rim-flange. Properly assembled, the wheel rims’ paint
dot should be aligned with the tires’ paint dot as shown in left fig-
ure.
Whenever a tire is dismounted from its wheel, it should be
remounted so that the tire and wheel are matched. If the tire’s
paint dot cannot be located, a line should be scribed on the tire
and wheel before dismounting to assure that it is remounted in
the same position.
TIRE MAINTENANCE
TIRE PLACARD
The “Tire Placard” is located on the left door (right door for right-hand side steering vehicle) lock pillar and
should be referred to tire information.
The placard lists the maximum load, tire size and cold tire pressure where applicable.
NOTE:
Whether rim size and/or maximum load are listed or not depends on regulations of each country.

3F-6 WHEELS AND TIRES
INFLATION OF TIRES
The pressure recommended for any model is carefully calculated to give a satisfactory ride, stability, steering,
tread wear, tire life and resistance to bruises.
Tire pressure, with tires cold, (after vehicle has set for 3 hours or more, or driven less than one mile) should be
checked monthly or before any extended trip. Set to the specifications on the “Tire Placard” located on the left
door (right door for right-hand side steering vehicle) lock pillar.
It is normal for tire pressure to increase when the tires become hot during driving.
Do not bleed or reduce tire pressure after driving. Bleeding reduces the “Cold Inflation Pressure”.
Higher than recommended pressure can cause :
Hard ride
Tire bruising or carcass damage
Rapid tread wear at center of tire
Unequal pressure on same axle can cause :
Uneven braking
Steering lead
Reduced handling
Swerve on acceleration
Lower than recommended pressure can cause :
Tire squeal on turns
Hard Steering
Rapid and uneven wear on the edges of the tread
Tire rim bruises and rupture
Tire cord breakage
High tire temperature
Reduced handling
High fuel consumption
TIRE ROTATION
To equalize wear, rotate tires according to left figure. Radial tires
should be rotated periodically. Set tire pressure.
NOTE:
Due to their design, radial tires tend to wear faster in the
shoulder area, particularly in front positions. This makes
regular rotation especially necessary.
[A] : 5-tire rotation
[B] : 4-tire rotation
LH : Left-hand drive
RH : Right-hand drive

ON-VEHICLE SERVICE
WHEEL
REMOVAL
1) Loosen wheel nuts by approximately 180° (half a rotation).
2) Hoist vehicle.
3) Remove wheel.
INSTALLATION
For installation, reverse removal procedure, noting the followings.
Wheel nuts must be tightened in sequence and to proper
torque to avoid bending wheel or brake disc.
Tightening order
: “A”-“B”-“C”-“D”
Tightening torque
Wheel nut (a) : 85 N·m (8.5 kg-m, 61.5 lb-ft) CAUTION:
Never use heat to loosen tight wheel because application
of heat to wheel can shorten life of wheel and damage
wheel bearings.
NOTE:
Before installing wheels, remove any build-up of corro-
sion on wheel mounting surface and brake disc mount-
ing surface by scraping and wire brushing. Installing
wheels without good metal-to-metal contact at mounting
surfaces can cause wheel nuts to loosen, which can later
allow a wheel to come off while vehicle is moving.

TIRE
MOUNTING AND DISMOUNTING
Use a tire changing machine to mount or dismount tires. Follow equipment manufacturer’s instructions. Do not
use hand tools or tire irons alone to change tires as they may damage tire beads or wheel rim.
Rim bead seats should be cleaned with a wire brush or coarse steel wool to remove lubricants, old rubber and
light rust. Before mounting or dismounting a tire, bead area should be well lubricated with approved tire lubri-
cant.
After mounting, inflate to specified pressure shown on tire placard so that beads are completely seated.
Install valve core and inflate to proper pressure.
REPAIR
There are many different materials and techniques on the market to repair tires. As not all of these work on all
types of tires, tire manufacturers have published detailed instructions on how and when to repair tires. These
instructions can be obtained from each tire manufacturer.WARNING:
Do not stand over tire when inflating. Bead may break when bead snaps over rim’s safety hump and
cause serious personal injury.
Do not exceed specified pressure when inflating. If specified pressure will not seat beads, deflate, re-
lubricate and reinflate.
Over inflation may cause bead to break and cause serious personal injury.
