Wheels and Tires
General Description
Tires DescriptionS6RW0D2401001
The tire is of tubeless type. The tire is designed to
operate satisfactorily with loads up to the full rated load
capacity when inflated to the recommended inflation
pressures.
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.
Tire Placard
The “Tire Placard” is located on the left or right door 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.

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 or
right door 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 accelerationLower 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
Matched Tires and Wheels (Steel Type)
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 “low 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 figure.
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.

Replacement Tires
When replacement is necessary, the original equipment
type tire should be used. Refer to the Tire Placard.
Replacement 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 clearance and tire or snow chain clearance to the
body and chassis.
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.
WARNING!
Do not mix different types of tires on the
same vehicle such as radial, bias and bias-
belted tires except in emergencies, because
handling may be seriously affected and may
result in loss of control.

The metric term for tire inflation pressure is the kilo
pascal (kPa). Tire pressures is usually printed in both
kPa and kgf/cm
2 on the “Tire Placard”.
Metric tire gauges are available from tool suppliers.
The chart, shown in the table, converts commonly used
inflation pressures from kPa to kgf/cm
2 and psi.
Wheels DescriptionS6RW0D2401002
Wheel Maintenance
Wheel repairs that use welding, heating, or peening are
not approved. All damaged wheels should be replaced.
Replacement Wheels
Wheels must be replaced if they are bent, dented, have
excessive lateral or radial runout, air leak through welds,
have elongated bolt holes, if lug wheel bolts won’t stay
tight, or if they are heavily rusted. Wheels with greater
runout than shown in the following may cause
objectional vibrations.
Replacement wheels must be equivalent to the original
equipment wheels in load capacity, diameter, rim with
offset and mounting configuration. A wheel of improper
size or type may affect wheel and bearing life, brake
cooling, speedometer / odometer calibration, vehicle
ground clearance and tire clearance to body and
chassis.How to Measure Wheel Runout
To measure the wheel runout, it is necessary to use an
accurate dial indicator. The tire may be on or off the
wheel. The wheel should be installed to the wheel
balancer of the like for proper measurement.
Take measurements of both lateral runout “a” and radial
runout “b” at both inside and outside of the rim flange.
With the dial indicator set in place securely, turn the
wheel one full revolution slowly and record every reading
of the indicator.
When the measured runout exceeds the specification
and correction by the balancer adjustment is impossible,
replace the wheel. If the reading is affected by welding,
paint or scratch, it should be ignored.
Lateral runout limit “a”
Aluminum wheel: 0.3 mm (0.012 in.)
Steel wheel: 0.9 mm (0.035 in.)
Radial runout limit “b”
Aluminum wheel: 0.3 mm (0.012 in.)
Steel wheel: 0.7 mm (0.028 in.)
Metric Lug Nuts and Wheel Studs
All models use metric lug nuts and wheel studs.
Metric lug nuts and wheel studs size
M12 x 1.25
If a broken stud is found, see “Front Wheel Hub, Disc,
Bolt and Bearing Check in Section 2B”, “Front Wheel

Equipment manufacture’s recommendations
Radial Tire Lead / Pull DescriptionS6RW0D2401006
“Lead / Pull” is the deviation of the vehicle from a straight
path on a level road even with no pressure on the
steering wheel.
Lead is usually caused by the following conditions.
• Improper tire and wheel alignment.
• Uneven brake assemblies.
• Tire construction.
The way in which a tire is built can produce lead in a
vehicle. An example of this is placement of the belt. Off
center belts on radial tires can cause the tire to develop
a side force while rolling straight down the road. If one
side of the tire has a little larger diameter than the other,
the tire will tend to roll to one side. This will develop a
side force which can produce vehicle lead.
The procedure in the figure (Lead Diagnosis) should be
used to make sure that wheel alignment is not mistaken
for tire lead.
• Part of the lead diagnosis procedure is different from
the proper tire rotation pattern currently in the owner
and service manuals. If a medium to high mileage tire
is moved to the other side of the vehicle, be sure to
check that ride roughness has not developed
• Rear tires will not cause lead.
Balancing Wheels DescriptionS6RW0D2401007
There are two types of wheel and tire balance: static and
dynamic. Static balance, as shown in figure, is the equal
distribution of weight around the wheel. Wheels that are
statically unbalanced cause a bouncing action called
tramp. This condition will eventually cause uneven tire
wear.Dynamic balance, as shown in 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.
