maximum weight the vehicle can carry.
Tire Identi¿ cation Number (TIN): A number on the sidewall of each tire providing
information about the tire brand and manufacturing plant, tire size, and date of manufacture.
InÀ ation Pressure: A measure of the amount of air in a tire.
kPa: Kilopascal, the metric unit for air pressure.
psi: Pounds per square inch, the English unit for air pressure.
B-pillar: The structural member at the side of the vehicle behind the front door.
Original Equipment (OE): Describes components originally equipped on the vehicle.
Vehicle Load Limit: The maximum value of the combination weight of occupants and
cargo.
Bead Area of the Tire: Area of the tire next to the rim.
Sidewall Area of the Tire: Area between the bead area and the tread.
Tread Area of the Tire: Area on the perimeter of the tire that contacts the road when it's
mounted on the vehicle.

Seating capacity means the total allowable number of vehicle occupants. Seating capacity
is described on the tire label.

Production options weight is the combination weight of installed regular production

CAUTION
Rotate unidirectional tires and radial tires that have an asymmetrical tread pattern or
studs only from front to rear, not from side to side. Tire performance will be weakened if
rotated from side to side.

(With limited-slip diff erential)
Don't use the following:
 


¾ Tires not of the designated size



¾ Tires of diff erent sizes or types at the same time



¾ Tires not suffi ciently infl ated
If these instructions aren't followed, the rotation of the left and right wheels will be
diff erent and will thus apply a constant load on the limited-slip diff erential.
This will cause a malfunction.

Replacing a Tire
WARNING
Always use tires that are in good condition:
Driving with worn tires is dangerous. Reduced braking, steering, and traction could result
in an accident.

If a tire wears evenly, a wear indicator will appear as a solid band across the tread.
Replace the tire when this happens.

New treadTread wear indicator
Worn tread

You should replace the tire before the band crosses the entire tread.
(With tire pressure monitoring system)
After adjusting the tire pressure, initialization of the tire pressure monitoring system is
necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on page 4-108 .
