The difference between both sides should be
within 0.6 kg.Park the vehicle on a paved and flat ground
and place the front wheels at straight ahead
direction.
Start the engine and let it run around 1,000
rpm.
Install the spring scale on the circumference o
f
the steering wheel and measure the steering
effort in both directions. 1.

3. Steering Effort Check ▶
Steering Angle Check ▶
Place the front wheel on a turning radius
measuring tool.
Turn the steering wheel to the its both ends
and measure the maximum steering angle. 1.

If the steering angle is out of the specified
value, check and adjust the toe-in.

Free Play Check ▶
Start the engine and place the wheels at
straight ahead direction.
Turn the steering wheel until the tires starts to
move and measure the distance on the
circumference of the steering wheel. 1.

If the free play is out of the specified value,
check the free play in steering column shaft
connection and steering linkage. Replace or
repair if necessary.

2) Typical Inspection
Tread
Inspect the tread condition on the tire surface
and various damages resulting from the
foreign materials, crack, stone or nail etc. If
there is any damage in the tire, repair or
replace it. 1.
Wear limit 2.
Measure the depth of the tire tread. If the
depth of the tread is below the specified
value, replace the tire -
You can see the protruded part in the
groove at the point with mark "▲", which
is the indicator of the tread wear limit.
The limit of the tread wear for all season
tires are 1.6 mm, which is the same as the
general tires, but the wear limit mark is
indicated as '↓'. -
-
Wear limit 1.6 mm
Higher than recommended pressure can cause hard ride, tire bruising or damage and rapid tread
wear at the center of the tire.
Excessive tire wear over the limit of the tread wear (1.6 mm) can cause lower sliding friction due to
longer braking distance, easy tire burst by foreign materials, tire hydroplaning, and tough brake and
steering wheel handling. -

Measure the dial runout and lateral runout
on both the inboard and outboard rim
flanges. - Tire inflation pressure -
Check the tire inflation pressure by
inspecting the tread width. -
Specified value 2.66 mm
Wheel runout
If wheel runout or tire runout is excessive, it
could result in abnormal wear of the tire.
Measure the runout with a dial gauge. 4.
Measure free radial runout on the tire tread. -
Specified value 2.03 mm
If any measurement exceeds the above
specifications, replace the applicable tires
or wheels -Tire inflation pressure 3.
Specified value 32 psi
Maintaining the specified tire ressure is
essential for comfortable riding, driving
safety, and long tire life. Incorrect inflation
pressures will increase tire wear and will
impair safety, vehicle handling, comfortable
driving and fuel economy. Always make sure
that the tire inflation pressure is correct.

Wheel balance 5.
Check the wheel balance when the wheel
is unbalanced or the tire is repaired.
The total weight of the wheel weight
should not exceed 150 g.
Ensure that the balance weight installed is
not projected over 3mm from the wheel
surface.
Use the specified aluminum wheel balance
weights for aluminum wheels.
Weight balance can be added by 5 g.
There are two types of weight balance,
tape type and adhesion type. -

Make sure to read the manual of the
manufacturer thoroughly before using
wheel balance tester. -
Change tire location
To avoid uneven wear of tires and to prolong
tire life, inspect and rotate your tires every
5,000 km. 6.
Mixing tires could cause to lose control while driving. Be sure to use the same size and type tires of
the same manufacturer on all wheels. -

When the vehicle is driven on a road surface covered with water at high speed, tires do not contact with
the road surface but rotate floating on a thin film of water.
It causes brake failure, lower traction force and losing the steering performance.
To prevent this, increase the tire inflation pressure, use tires with leaf shape tread which is not worn.
However, it is a best measure to drive slowly. Hydro Planing ▶

If weight is not equally distributed around the wheel, unbalance centrifugal force by the wheel rotation
produces vibration. As the centrifugal force is produced proportional to the square of the rotating speed,
the wheel weight should be balanced even at high speed. There are two types of the tire and wheel
balancing: static and dynamic. Abnormal vibration may also occur due to unbalanced rigidity or size of
tires.
Static Balance ▶
When the free rotation of the wheel is allowed,
the heavier part is stopped on the bottom if the
wheel weight is unbalanced and this is called
"Static Unbalance". Also, the state at which tire's
stop position is not same is called "Static
Balance" when the wheel is rotated again. If the
part A is heavier as shown in the figure 1, add
the balance weight of a weight corresponding to
unbalanced weight from B to A to maintain the
static balance. If the static balance is not
maintained, tramping, up and down vibration of
the wheels, occurs.
Dynamic Balance ▶
The static unbalance of the wheel creates the
vibration in the vertical direction, but the dynamic
unbalance creates the vibration in the lateral
direction. As shown in the figure 2 (a), if two
parts, (2) and (3), are heavier when the wheels
are under the static balance condition, dynamic
unbalance is created, resulting in shimmy, left
and right vibration of the wheels, and the torque
Fxa is applied in the axial direction. To correct
the dynamic unbalance, add the balance weight
of a same weight for two points of the
circumference of the rim, A and B, as shown in
the figure 2 (b), and apply the torque in the
opposite direction to the torque Fxa to offset in
order to ensure smooth rotation of the wheel.
