3F-2 WHEELS AND TIRES
GENERAL DESCRIPTION
TIRES
This vehicle is equipped with the following tire.
Tire size
: 165/70R14
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.
WHEELS
Standard equipment wheels are the following steel wheel.
Wheel size
: 14 x 4 1/2 J
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.
The metric term for tire inflation pressure is the kilo pascal (kPa).
Tire pressures is usually printed in both kPa and psi on the “Tire
Placard”.
Metric tire gauges are available from tool suppliers.
The chart, shown the table, converts commonly used inflation
pressures from kPa to psi.
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 nuts won’t stay tight, or if they are heavily rusted. Wheels with greater
runout than shown in figure below 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.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.

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 (1) and radial runout
(2) at both inside and outside of the rim flange. With the dial indi-
cator 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 correc-
tion 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” : 0.90 mm (0.035 in.)
Radial runout limit
“b” : 0.70 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
DIAGNOSIS
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 the equal distri-
bution of weight around the wheel. Wheels that are statically
unbalanced cause a bouncing action called tramp. This condition
will eventually cause uneven tire wear.
1. Heavy spot wheel tramp [A] : Before correction
2. Balance weights addition point [B] : Corrective weights
3. C/L of spindle

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.
