Note :
Tyre pressure should be maintained as indicated on the label affixed to the driver's door frame.
Low pressure can cause tyre damage and adversely affect vehicle handling.
High pressure can increase road shocks and reduce traction.
Note :
The air pressure of the Tyre should be maintained as indicated in the label instruction on the driver's door
or frame of driver's door.
Lower pressure can cause burst and adverse vehicle handling.
On the other hand, higher pressure can cause shock-burst and reduce gripping effect.
SERVICING
Servicing refers to general maintenance procedures to be performed by qualified service personnel.
WHEEL NUT TORQUES
Wheel Nut Torque Nm(kgfm/lbft)
117.7 ± 9.8 (12.0 ± 1.0 / 86.8 ± 7.2)
TYRE ROTATION
When the front Tyre size and the rear size are different,
interchange front wheels and rotate the rear wheels as shown
in the figure.
When the front and rear Tyres are the same size, rotate the
wheels as shown in the figure.
For of radial Tyres, interchange the front and the rear wheels
on the same side as shown in the figure.
If one-sided Tyre w ear appears on radial Tyres, rotate the
wheels as shown in the figure.
Note:
After rotation, adjust the front and rear Tyre pressure and
be sure to check wheel nut tightness.
INSPECTION AND REPAIR
Make necessary correction or parts replacement if wear, damage or any other abnormal conditions are found through
inspection.
VISUAL CHECK
Inspect all disassembled parts for wear, damage or other
abnormal conditions.
MEASURE W HEEL RUNOUT mm(in)
16 inch Alumi Less than 0.55 (0.022)
14 inch Steel Less than 1.2 (0.047)
15 inch, 16inch Steel Less than 1.5 (0.059)
If the measured value exceed the specified limit, the wheel
must be replaced.
MEASURE W HEEL UNBALANCE
Using a wheel balancing equipment.
Install on the side rim of the wheel a balance weight to offset
unbalance.
Balance weight for the wheel should not exceed 170g in total,
and 140g is the maximum amount for either side.
IMPORTANT OPERATIONS
1., 1a. Tyre Assembly
Align the match mark (approx. 10mm diameter paint mark) of
wheel with match mark (approx. 8mm diameter red paint mark)
of Tyre to assemble. If the match mark at wheel has
disappeared, align with air valve to assemble.

TROUBLESHOOTING
Typical examples of abnormal Tyre tread wear and major causes :
CAUTION:
Similar wear patterns can be caused by worn suspension parts, misalignment of wheels and Tyres, and other
suspension related problems.
Spotty wear - wear localized
on shoulder section. In
extreme cases, the tire
becomes polygonal in shape.
Tire or wheel out of
round or distorted. Hub or knuckle out
of round or distorted. Play in hub bearings
or ball joints. Rotating parts out of
balance.
Tread wear one-sided.
Rotating parts out of
balance. Tire or wheel out of
round. Hub or knuckle out
of round or distorted.
Localized tread wear.
Once spotty wear develops in
tread due to hard braking or
abrupt starting, localized wear
tends to be accelerated.
Techline
Shoulder wear (generally
wear develops on outer
shoulder).
Camber or toe-in
incorrect. Shoulder wear
caused by repeated
hard-cornering.
Wear on shoulders at points
opposed to each other.
Tire or wheel out of
round or distorted. Play in bearings or
ball joint.
Premature wear on
shoulders.
Flexing of tire excessive due
to under-inflation.
One-sided feather edging.
Wear caused by
repeated hard-
cornering.
Camber or toe-in
incorrect.
