Precautions
Precaution for Emergency Flat Tire Repair KitS7RS0B2400001
WARNING!
Flat tire repair sealant including in kit is
harmful. Be sure to observe the following.
Otherwise, your health may be ruined.
• If swallowed, get medical attention immediately.
• Keep out of reach of children.
• Select place where there is good ventilation for this work.
• If it enters eye or contacts skin, wash thoroughly with water. If anything
abnormal still rema ins, get medical
attention immediately.
• Do not discard tire containing sealant as it is. Make sure to remove sealant from tire,
referring to “Tire Repair for Emergency
Repaired-Tire with Sealant”.
• Dispose of sealant as waste oil.

CAUTION!
• When tire repaired with Emergency Flat Tire Repair Kit is brought in, remove flat
tire repair sealant from tire and repair flat
tire referring to “Tire Repair for Emergency
Repaired-Tire with Sealant”.
• Sealant expiration date is printed on bottle label. if it expires, sealant should be
replaced with a new one to ensure
emergency flat tire repair.

General Description
Tires DescriptionS7RS0B2401001
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 satisfacto ry 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
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 acceleration

Radial Tire Waddle DescriptionS7RS0B2401005
Waddle is side to side movement at the front and/or rear
of the vehicle. It is caused by the steel belt not being
straight within the tire. It is most noticeable at a low
speed, 8 to 48 kph (5 to 30 mph).
It is possible to locate the f aulty tire by road testing the
vehicle. If it is on the rear , the rear end of the vehicle
shakes from side to side or “waddles”. To the driver in
the seat, it feels as though someone is pushing on the
side of vehicle.
If the faulty tire is on the front, waddling is more visual.
The front sheet metal appears to be moving back and
forth and the driver feels as though he is at the pivot
point in vehicle.
Waddle can be quickly diagnosed by using Tire Problem
Detector (TPD) and following the equipment
manufacture’s recommendations.
If TPD is not available, an alternative method of
substituting known-good tire / wheel assemblies can be
used as follows, although it takes a longer time. 1) Ride vehicle to determine whether the front or rear
waddles.
2) Install tires and wheels that are known to be good (on similar vehicle) in place of those on waddling end
of vehicle. If waddling end cannot be identified,
substitute rear ones.
3) Road test again. If improvement is noted, reinstall originals one at a time till w addle causal tire is found.
If no improvement is noted, install known-good tires
in place of all four. Then reinstall originals in the
same manner.
