WHEELS AND TIRES
NOTE:
All wheel fasteners are important attaching parts in that they could affect the performance of vital parts
and systems, and / or could result in major repair expense. They must be replaced with one of the same
part number or with an equivalent part if replacement becomes necessary. Do not use a replacement part
of lesser quality or substitute design. Torque values must be used as specified during reassembly to as-
sure proper retention of all parts.
There is to be no welding as it may result in extensive damage and weakening of the metal.

GENERAL DESCRIPTION
TIRES
This vehicle is equipped with following tire. P215 / 65 R16, 215 / 65 R16 or 235 / 60 R16
The tires are of tubeless type. The tires are designed to operate satisfactorily with loads up to the full rated load
capacity when inflated to the recommended inflation pressure.
Correct tire pressures and driving habits have an important influence on tire life. Heavy cornering, excessively rapid
acceleration, and unnecessary sharp braking increase tire wear.
WHEELS
Standard equipment wheels are following steel wheel. 16 6 1 / 2 J or 16 7JJ
REPLACEMENT TIRES
When replacement is necessary, the original equipment type tire should be used. Refer to the Tire Placard. Re-
placement tires should be of the same size, load range and construction as those originally on the vehicle. Use
of any other size or type tire may affect ride, handling, speedometer / odometer calibration, vehicle ground clear-
ance and tire or snow chain clearance to the body and chassis.
NOTE:
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 may be seriously affected and may result in loss of control.
It is recommended that new tires be installed in pairs on the same axle. If necessary to replace only one tire, it
should be paired with the tire having the most tread, to equalize braking traction.

DIAGNOSIS TABLE
Refer to SECTION 3.
BALANCING WHEELS
There are two types of wheel and tire balance: static and dynamic.
Static balance, as shown in left figure, is equal distribution of weight
around wheel. Wheels that are statically unbalanced cause bounc-
ing action called tramp. This condition will eventually cause uneven
tire wear.
Dynamic balance, as shown in left figure, is equal distribution of
weight on each side of 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 PROCEDURE
Deposits of mud, etc. must be cleaned from inside of rim.
WARNING:
Stones should be removed from tread in order to avoid operator injury during spin balancing and to
obtain good balance.
Tire should be inspected for any damage, then balanced according to equipment manufacturer's recommendation.
OFF-VEHICLE BALANCING
Most electronic off-vehicle balancers are more accurate than 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 manufacturer's
instructions during balancing operation.

Higher than Recommended Pressure Can Cause:
1. Hard ride
2. Tire bruising or carcass damage
3. Rapid tread wear at center of tire
Unequal Pressure on Same Axle Can Cause:
1. Uneven braking
2. Steering lead
3. Reduced handling
4. Swerve on acceleration
Valve caps should be kept on valves to keep dust and
water out.Lower than Recommended Pressure Can Cause:
1. Tire squeal on turns
2. Hard steering
3. Rapid and uneven wear on the edges of the tread
4. Tire rim bruises and rupture
5. Tire cord breakage
6. High tire temperatures
7. Reduced handling
8. High fuel consumption
MAINTENANCE AND MINOR ADJUSTMENTS
WHEEL AND TIRE
Wheel repairs that use welding, heating, or peening are not approved. All damaged wheels should be replaced.
STUDS
If a broken stud is found, see Section 3E (rear) or Section 3D (front) for Note and Replacement procedure.
MATCHED TIRES AND WHEELS
(For vehicle equipped with steel wheels)
Tires and wheels are matchmounted at the assembly plant.
This means that the radially stiffest part of the tire, or ªhigh spotº, is
matched to the smallest radius or ªlow spotº of the wheel.
This is done to provide the smoothest possible ride.
The ªhigh spotº of the tire is originally marked by paint dot on the
outboard sidewall. This paint dot will eventually wash off the tire.
The ªlow spotº of the wheel is originally marked by paint dot on the
wheel rim-flange. Properly assembled, the wheel rims' paint dot
should be aligned with the tires' paint dot as shown in left figure.
Whenever a tire is dismounted from its wheel, it should be re-
mounted 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 posi-
tion.
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 three 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 side
of instrument panel.
It is normal for tire pressure increase when the tires become hot during driving. Do not bleed or reduce tire pressure
after driving. Bleeding reduces the ªCold Inflation Pressureº.

GENERAL DESCRIPTION
The drive shaft joint is a constant velocity joint (C.V. joint) which slides in the axial direction. The joint is composed
of an outer race, cage, inner race and balls. In the turning direction, the joint rotates in the same way as a ball bear-
ing. The balls lock rotation completely and transmit drive. In addition this vehicle is also characterized by a function
that the shaft can slide through the balls in the grooves of the outer race in the extension / contraction direction of
the drive shaft.

GENERAL DESCRIPTION
Most universal joints require no maintenance. They are lubricated for life and can not be lubricated on the vehicle.
If a universal joint becomes noisy or worn, it must be replaced.
The propeller shaft is a balanced unit. Handle it carefully so that balance can be maintained.
