INSPECTION
1. INSPECT TIRES
(a) Check the tires for wear and proper inflation
pressure.
Cold tire inflation pressure
(b) Using a dial indicator, check the runout of the tires.
Tire runout:
1.4 mm (0.055 in.) or less
2. ROTATE TIRES
HINT:
Rotate the tires as shown in the illustration.
3. INSPECT WHEEL BALANCE (for Steel Wheel)
(a) Check and adjust the off-the-car balance.
Imbalance after adjustment:
8.0 g (0.018 lb.) or less.

4. INSPECT WHEEL BALANCE (for Non-steel Wheel)
(a) Check and adjust the off-the-car balance.
Imbalance after adjustment:
8.0 g (0.018 lb.) or less.
NOTICE:
• Use a cleaning detergent to remove dirt, oil
and water from the surface where the balance
weight is to be adhered.
• Do not touch the sticking surface of the tape.
• Adhere the sticking type balance weight to
the flat position shown in the illustration.
• Push the balance weight securely with a
finger to adhere it to the position.
• Do not reuse the balance weight.
HINT:
• The inner side balance weight should be installed
by clipping it to the rim.
• If necessary, check and adjust the on-the-car
balance.

REPAIR
1. INTRODUCTION
(a) This section introduces ways to determine whether
the run-flat tire is repairable or not. Repair must be
performed by following the appropriate procedures.
If a flat tire occurs, it is possible to drive a maximum
of 160 km (100 miles) at a speed below 90 km/h (55
mph) due to the reinforced sidewalls. However, if
the customer continues to drive with low tire
pressure (less than about 100 kPa (1.0 kgf/cm
2,
14.5 psi) and tire pressure warning light is on), the
inside of the sidewall will gradually deteriorate and
the run-flat performance may be reduced.
Therefore, the tires may require replacement.
However, there are some cases where it is possible
to repair a run-flat tire using the same repair method
as for normal tires. Use the following flowchart to
determine if a run-flat tire is repairable.
NOTICE:
When performing repairs, follow the Rubber
Manufacturers Association (RMA) repair
procedures.
2. REPAIR PROCEDURE (CUSTOMER INTERVIEW)
(a) The tire pressure warning system can help
determine the history of the tire's use. The driving
conditions the tire was subjected to while the tire
pressure warning light was on should be obtained
from the customer. Also, make sure to ask the
following questions.
(1) Was the vehicle driven at a speed over 90 km/h
(55 mph) with the tire pressure warning light
on?
(2) Was the vehicle driven over 160 km (100 miles)
with the tire pressure warning light on?
A "Yes" response to either of the above will
greatly reduce the chance of tire repairability.
3. TECHNICIAN TIRE INSPECTION
(a) After the customer interview, it is necessary to
conduct a thorough inspection of the tire after it has
been removed from the wheel. As it is difficult to
identify a tire with low pressure visually, check the
pressure of each tire to determine the tire(s) causing
the low-pressure warning. If the tire is found to be
repairable, follow the RMA repair procedures.
NOTICE:
The deflated tire may be extremely hot, which
may cause injury, so allow the tire to cool prior
to handling.
