Compact spare tyre replacement (if equipped)
A compact spare tyre has a shorter
tread life than a regular size tyre.
Replace it when you can see the
tread wear indicator bars on the tyre.The replacement compact spare tyre
should be the same size and design
tyre as the one provided with your
new vehicle and should be mountedon the same compact spare tyre
wheel. The compact spare tyre is notdesigned to be mounted on a regular
size wheel, and the compact spare
tyre wheel is not designed for mount-
ing a regular size tyre. Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim widthand offset.
Tyre traction
Tyre traction can be reduced if you
drive on worn tyres, tyres that are
improperly inflated or on slippery
road surfaces. Tyres should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tyre maintenance In addition to proper inflation, correct wheel alignment helps to decrease
tyre wear. If you find a tyre is worn
unevenly, have your dealer check thewheel alignment.
When you have new tyres installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tyre life. Additionally, a tyre should
always be rebalanced if it is removedfrom the wheel.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tyre clearance,
snow chain clearance,speedometer and odometer cal-
ibration, headlight aim and
bumper height.

Tyre sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tyre and also provides
the tyre identification number (TIN)
for safety standard certification. TheTIN can be used to identify the tyre incase of a recall.
1. Manufacturer or brand name
Manufacturer or Brand name is
shown.
2. Tyre size designation
A tyre’s sidewall is marked with a tyre
size designation. You will need this
information when selecting replace-
ment tyres for your car. The following
explains what the letters and num-
bers in the tyre size designationmean.
Example tyre size designation:
(These numbers are provided as an
example only; your tyre size designa-
tor could vary depending on your
vehicle.) 225/45R18 97V
225 - Tyre width in millimeters.
45 - Aspect ratio. The tyre’s section
height as a percentage of its width.
R - Tyre construction code (Radial).
18 - Rim diameter in inches. 97 - Load Index, a numerical code
associated with the maximum
load the tyre can carry.
V - Speed Rating Symbol. See the
speed rating chart in this section
for additional information.
Wheel size designation
Wheels are also marked with impor-
tant information that you need if you
ever have to replace one. The follow-
ing explains what the letters and
numbers in the wheel size designa-tion mean.
Example wheel size designation: 7.5JX18
7.5 - Rim width in inches. J - Rim contour designation.
18 - Rim diameter in inches.

4. Tyre ply composition and material
The number of layers or plies of rub-
ber-coated fabric in the tyre. Tyre
manufacturers also must indicate the
materials in the tyre, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and theletter "B" means belted-bias ply con-
struction.
5. Maximum permissible inflation
pressure
This number is the greatest amount of air pressure that should be put in
the tyre. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tyre and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tyre. When
replacing the tyres on the vehicle,
always use a tyre that has the same
load rating as the factory installed
tyre.
7. Uniform tyre quality grading
Quality grades can be found where
applicable on the tyre sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate ofthe tyre when tested under controlled
conditions on a specified govern-
ment test course. For example, a tyre
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tyre graded100.
The relative performance of tyres depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
These grades are molded on the
side-walls of passenger vehicle
tyres. The tyres available as standard
or optional equipment on your vehi-
cle may vary with respect to grade.
