Size Designation
EXAMPLE:P215/65R15
NOTE
European/Japanese metric tire sizing is based on
European/Japanese design standards. Tires designed
to these standards have the tire size molded into the
sidewall beginning with the section width. The letter
“P” is absent from this tire size designation. Exam-
ple: 215/65R15 96H.
LT (Light Truck) -metric tire sizing is based on
U.S.A. design standards. The size designation for
LT-metric tires is the same as for P-metric tires
except for the letters “LT” that are molded into the
sidewall preceding the size designation. Example:
LT235/85R16.
Temporary spare tires are high pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter “T”
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.Service Description

Maximum Load
Maximum load indicates the maximum load this tire is
designed to carry. PPassenger car tire size based on U.S.A. design

Ratio of section height to section width of tire.
RConstruction code
• “R” means radial construction.

15 Rim diameter in inches (in)95Load index
A numerical code associated with the maxi-

HSpeed symbol
A symbol indicating the range of speeds at
which a tire can carry a load corresponding to
its load index under certain operating condi-

The maximum speed corresponding to the
speed symbol should only be achieved under
specified operating conditions. (i.e. tire pres-
sure, vehicle loading, road conditions and
posted speed limits)

!
Overloading of your tire is dangerous. Over-
loading can cause tire failure, affect vehicle
handling, and increase your stopping distance.
Use tires of the recommended load capacity for
your vehicle. Never overload them.

Tire inflation pressures
N00939300798
Proper tire inflation pressure is essential for the safe and satis-
factory operation of your vehicle. The wrong tire pressure will
cause problems in three major areas:
Safety
Too little pressure increases flexing in the tire and can
cause tire failure. Too much pressure can cause a tire to
lose its ability to cushion shock. Objects on the road and
potholes could then cause tire damage that may result in
tire failure.
Economy
The wrong tire pressure can cause uneven wear patterns in
the tire tread. These abnormal wear patterns will reduce
the tread life, and the tire will have to be replaced sooner.
Too little pressure also makes it harder for the tire to roll,
and this uses up more fuel.
Ride comfort and vehicle stability
The superior riding experience built into your vehicle
partly depends on the correct tire pressure. Too much
pressure gives an uncomfortable and jarring ride. Too lit-
tle pressure feels as if your vehicle is slow to respond.
Unequal tire pressures can make steering your vehicle
uneven and unpredictable.
The correct tire pressure for your vehicle is listed on the plac-
ard attached to the sill of the driver’s door.
(Refer to “Tire and loading information placard” on page 9-3.)The recommended inflation pressures should be used for the
tires listed below.
Tire pressures should be checked, and adjusted if necessary, at
least once a month.
Pressures should be checked more often whenever weather
temperatures change severely, because tire pressures change
with outdoor temperatures. The pressures listed are always
“cold inflation pressure”.
Cold inflation pressure is measured after the vehicle has been
parked for at least three hours or is driven less than 1 mile
(1.6 km) after having been parked for three hours.
Cold inflation pressure must not go above the maximum values
molded into the tire sidewall. After driving several miles, your
tire inflation pressure may increase 14 to 41 KPA, 2 to 6 PSI
from the cold inflation pressure. Do not let air out of the tires to
get back to the specified cold pressure, or your tire pressure
will be too low.
Check your tires each time you refuel. If one tire looks lower
than the others, check the pressure for all of them.
You should also take the following safety precautions:
Keep your tires inflated to the recommended pressures.
(See the tire and loading information placard attached to
the sill of the driver’s door.)
Stay within the recommended load limits.
Make sure that the weight of any load in your vehicle is
evenly distributed.

CAUTION
!A compact spare tire can be fitted temporarily in
place of a tire that has been removed during the tire
rotation. However, it must not be included in the
regular tire rotation sequence.Tires that do not have arrows showing rotation direction

CAUTION
!If the tires have arrows (A) indicating the correct
direction of rotation, swap the front and rear tires
on the left-hand side of the vehicle and the front and
rear tires on the right-hand side of the vehicle sepa-
rately. Keep each tire on its original side of the vehi-
cle. When installing the tires, make sure the arrows
point in the direction in which the wheels will turn
when the vehicle moves forward. Any tire whose
arrow points in the wrong direction will not perform
to its full potential.
