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.
Intended outboard sidewall
1)The sidewall that contains a
whitewall, bears white lettering or
bears manufacturer, brand, and/or
model name molding that is higher
or deeper than the same molding
on the other sidewall of the tire, or

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.
