Consumer information and Reporting safety defectsFor U.S.A.
The following information has been com-
piled according to Code of Federal Regu-
lations Title 49, Part 575 .Tire information
Tire labeling
Many markings (e.g. Tire size, Tire
Identification Number or TIN) are
placed on the sidewall of a tire by tire
manufacturers. These marking can
provide you with useful information on
the tire.
Tire size
Your vehicle comes equipped with P-
Metric tire size. It is important to un-
derstand the sizing system in select-
ing the proper tire for your vehicles.
Here is a brief review of the tire sizing
system with a breakdown of its indi-
vidual elements.
P Metric
With the P-Metric system, Section
Width is measured in millimeters. To
convert millimeters into inches, divide
by 25.4. The Aspect Ratio (Section
Height divided by Section Width)
helps provide more dimensional infor-
mation about the tire size. Example:
(1) P = Certain tire type used on light
duty vehicles such as passenger cars
(2) Section Width in millimeters
(3) Aspect Ratio (= section height
section width).
(4) R = Radial Construction
(5) Rim diameter in inches
Load and Speed Rating Descrip-
tions
The load and speed rating descrip-
tions will appear following the size
designation.
They provide two important facts
about the tire. First, the number des-
ignation is its load index. Second, the
letter designation indicates the tire s
speed rating.
Example:

which specifies the maximum load a
tire can carry at the speed indicated
by its speed symbol, at maximum in-
flation pressure.
For example,
90 means 1,323 lbs
(600 kg), 89 means 1,278 lbs (580
kg).
(7) Speed Rating: An alphabetical
system describing a tire s capability to
travel at established and predeter-
mined speeds.
For example, V means 149 mph
(240 km/h)
Tire Identification Number (TIN)
Tire Identification Number (TIN) is
marked on the intended outboard
sidewall. The TIN is composed of four
groups. Here is a brief review of the
TIN with a breakdown of its individual
elements. (1) Manufacturer
s Identification
Mark
(2) Tire Size
(3) Tire Type Code
(4) Date of Manufacture
The first two figures identify the week,
starting with 01 to represent the first
full week of the calendar year; the
second two figures represent the
year. For example, 0101 means the
1st week of 2001.
Other markings
The following makings are also
placed on the sidewall.
Maximum permissible inflation
pressure
The maximum cold inflation pressure
to which this tire may be inflated. For
example, 300 kpa (44 PSI) MAX.
PRESS
Maximum load rating
The load rating at the maximum per-
missible weight load for this tire. For
example, MAX. LOAD 580 kg (1279
LBS) @ 300 kpa (44 PSI) MAX.
PRESS.
Load indices apply only to the
tire, not to the vehicle. Putting a
load rated tire on any vehicle
does not mean the vehicle can
be loaded up to the tire s rated
load.
Speed ratings apply only to
the tire, not to the vehicle. Put-
ting a speed rated tire on any
vehicle does not mean the ve-
hicle can be operated at the
tire s rated speed.
The speed rating is void if the
tires are worn out, damaged,
repaired, retreaded, or other-
wise altered from their original
condition. If tires are repaired,
retreaded, or otherwise al-
tered, they may not be suitable
for original equipment tire de-
signed loads and speeds.

Vehicle placard
The vehicle placard is affixed to the
driver s side B-pillar.
Example: The vehicle placard shows original
tire size, recommended cold tire infla-
tion pressure on each tire at maxi-
mum loaded vehicle weight, seating
capacity and loading information.
Adverse safety consequences
of under-inflation
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to rapidly
become hot. A sharp increase in tem-
perature could cause tread separa-
tion, and failure of the tire(s). Possi-
ble resulting loss of vehicle control
could lead to an accident.
Measuring and adjusting air
pressure to achieve proper infla-
tion
Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and be-
fore any long journey. Check the tire
pressures when the tires are cold.
Use a pressure gauge to adjust the
tire pressures to the specific values.
Driving even a short distance warms
up the tires and increases the tire
pressures. Also, the tire pressures are affected by the outside tempera-
ture. It is best to check tire pressure
outdoors before driving the vehicle.
When a tire becomes warm, the air in-
side it expands, causing the tire pres-
sure to increase. Be careful not to
mistakenly release air from a warm
tire to reduce its pressure.
Glossary of tire terminology
Cold tire pressure
The pressure in a tire that has been
driven less than 1 mile or has been
standing for three hours or more.
Maximum inflation pressure
The maximum cold inflation pressure
to which a tire may be inflated.
Recommended inflation pres-
sure
The cold inflation pressure recom-
mended by a vehicle manufacturer.

asymmetrical tire that has a particu-
lar side that must always face out-
ward when mounting on a vehicle.
Accessory weight
The combined weight (in excess of
those standard items which may be
replaced) of floor mats, leather seats
and cross bars to the extent that these
items are available as factory-in-
stalled equipment (whether installed
or not).
Curb weight
The weight of a motor vehicle with
standard equipment including the
maximum capacity of fuel, oil, and
coolant and air conditioning.
Maximum loaded vehicle weight
The sum of curb weight, accessory
weight, vehicle capacity weight and
production options weight.
Normal occupant weight
150 lbs (68 kg) times the number of
occupants (3 occupants).
Occupant distribution
Distribution of occupants in a vehicle,
2 in front, 1 in rear seat.
Production options weight
The combined weight of those in-
stalled regular production options weighing over 5.1 lbs (2.3 kg) in ex-
cess of those standards items which
they replace, not previously consid-
ered in curb weight or accessory
weight.
Vehicle capacity weight
The total weight of cargo, luggage
and occupants that can be added to
the vehicle.
Vehicle maximum load on a tire
Load on an individual tire that is deter-
mined by distributing to each axle its
share of the maximum loaded vehicle
weight and dividing by two.
Vehicle normal load on a tire
Load on an individual tire that is deter-
mined by distributing to each axle its
share of the curb weight, accessory
weight, and normal occupant weight
and dividing by two.
Tire care maintenance and
safety practices
Check on a daily basis that the tires
are free from serious damage, nails,
and stones. At the same time, check
the tires for abnormal wear.
Inspect the tire tread regularly and
replace the tires before their tread wear indicators become visible. When
a tire
s tread wear indicator becomes
visible, the tire is worn beyond the ac-
ceptable limit and must be replaced
immediately. With a tire in this condi-
tion, driving at even low speeds in wet
weather can cause the vehicle to hy-
droplane. Possible resulting loss of
vehicle control can lead to an acci-
dent.
To maximize the life of each tire and
ensure that the tires wear uniformly, it
is best to rotate the tires every 7,500
miles (12,500 km). Rotating the tires
involves switching the front and rear
tires on the right-hand side of the ve-
hicle and similarly switching the front
and rear tires on the left-hand side of
the vehicle. (Each tire must be kept on
its original side of the vehicle.) Re-
place any damaged or unevenly worn
tire at the time of rotation. After tire ro-
tation, adjust the tire pressures and
make sure the wheel nuts are correct-
ly tightened. A tightening torque spec-
ification and a tightening sequence
specification for the wheel nuts can be
found Flat tires section in chapter 9.

Vehicle load limit how to de-
termine
The load capacity of your vehicle is
determined by weight, not by avail-
able cargo space. The load limit of
your vehicle is shown on the vehicle
placard attached to the driver s side
B-pillar. Locate the statement The
combined weight of occupants and
cargo should never exceed XXX kg or
XXX lbs on your vehicle s placard.
The vehicle placard also shows seat-
ing capacity of your vehicle.
The total load capacity includes the
total weight of driver and all passen-
gers and their belongings, any cargo,
any optional equipment such as a
trailer hitch, roof rack or bike carrier,
etc., and the tongue load of a trailer.
Therefore cargo capacity can be cal-
culated by the following method.
Cargo capacity = Load limit (total
weight of occupants + total weight of
optional equipment + tongue load of a
trailer (if applicable))
For towing capacity information and
weight limits, refer to Trailer towing
section in chapter 8.
Calculating total and load capac-
ities varying seating configura-
tions
Calculate the available load capacity
as shown in the following examples:
Example 1A
Vehicle capacity weight of the vehicle
is 900 lbs (408 kg), which is indicated
on the vehicle placard with the state-
ment The combined weight of occu-
pants and cargo should never exceed
900 lbs or 408 kg .
For example, if the vehicle has one
occupant weighing 154 lbs (70 kg)
plus cargo weighing 662 lbs (300 kg). 1. Calculate the total weight.
2. Calculate the available load capac-
ity by subtracting the total weight from
the vehicle capacity weight of 900 lbs
(408 kg).
3. The result of step 2 shows that a
further 84 lbs (38 kg) of cargo can be
carried.
D00117
Total weight
= 154 lbs (70 kg) + 662 lbs (300 kg)
=
816 lbs (370 kg)(Occupant) (Cargo)

Example 1B
For example, if a person weighing 176
lbs (80 kg) now enters the same vehi-
cle (bringing the number of occupants
to two), the calculations are as fol-
lows:
1. Calculate the total weight.
2. Calculate the available load capac-
ity.
3. The total weight now exceeds the
capacity weight by 92 lbs (42 kg), so
the cargo weight must be reduced by
92 lbs (42 kg) or more.
Example 2A
Vehicle capacity weight of the vehicle
is 900 lbs (408 kg), which is indicatedon the vehicle placard with the state-
ment
The combined weight of occu-
pants and cargo should never exceed
408 kg or 900 lbs .
For example, the vehicle has one oc-
cupant weighing 165 lbs (75 kg) plus
cargo weighing 375 lbs (170 kg). In
addition, the vehicle is fitted with a
trailer hitch weighing 22 lbs (10 kg), to
which is attached a trailer weighing
1,764 lbs (800 kg). 10% of the trailer
weight is applied to the trailer tongue
(i.e. Tongue load = 176 lbs (80 kg)).
1. Calculate the total weight.
2. Calculate the available load capac-
ity.
