tire can carry at the speed indicated
by its speed symbol, at maximum in-
flation pressure.
For example, “94” means 1,477 lbs
(670 kg).

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.
T Other markings
The following makings are also
placed on the sidewall. V Maximum permissible inflation
pressure
The maximum cold inflation pressure
to which this tire may be inflated. For
example, “300 kpa (44 PSI) MAX.
PRESS” V Maximum load rating
The load rating at the maximum per-
missible weight load for this tire. For
example, “MAX. LOAD 670 kg (1477
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.
y 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.
yThe 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.

TVehicle placard
The vehicle placard is affixed to the
driver’s side door 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.
T 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). Possible
resulting loss of vehicle control could
lead to an accident. T 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

asymmetrical tire that has a particu-
lar side that must always face out-
ward when mounting on a vehicle.
y 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). y Curb weight
The weight of a motor vehicle with
standard equipment including the
maximum capacity of fuel, oil, and
coolant and air conditioning. y Maximum loaded vehicle weight
The sum of curb weight, accessory
weight, vehicle capacity weight and
production options weight. y Normal occupant weight
150 lbs (68 kg) times the number of
occupants (3 occupants). y Occupant distribution
Distribution of occupants in a vehicle,
2 in front, 1 in rear seat. y 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.
y Vehicle capacity weight
The total weight of cargo, luggage
and occupants that can be added to
the vehicle. y 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. y 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
y 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. y 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.
y 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” in Chapter 9.

3. The result of step 2 shows that a
further 162 lbs (73 kg) of cargo can be
carried.
Example 2B
For example, if a person weighing 143
lbs (65 kg) and a child weighing 40 lbs
(18 kg) now enter the same vehicle
(bringing the number of occupants to
three), and a child restraint system
weighing 11 lbs (5 kg) is installed inthe vehicle for the child to use, the cal-
culations are as follows:
1. Calculate the total weight.
2. Calculate the available load capac-
ity.
3. The total weight now exceeds the
capacity weight by 32 lbs (15 kg), so
the cargo weight must be reduced by
32 lbs (15 kg) or more.
„ Determining compatibility of
tire and vehicle load capaci-
ties
The sum of four tires’ maximum load
ratings must exceed the maximum
loaded vehicle weight (“GVWR”). In
addition, sum of the maximum load
ratings of two front tires and of two
rear tires must exceed each axle’s
maximum loaded capacity (“GAWR”).
Original equipment tires are designed
to fulfill those conditions.
The maximum loaded vehicle weight
is referred to Gross Vehicle Weight
Rating (GVWR). And each axle’s
maximum loaded capacity is referred
to Gross Axle Weight Rating
(GAWR). The GVWR and each axle’s
GAWR are shown on the vehicle cer-
tification label affixed to the driver’s
door.
The GVWR and front and rear
GAWRs are determined by not only
the maximum load rating of tires but
also loaded capacities of the vehicle’s

suspension, axles and other parts of
the body.
Therefore, this means that the vehicle
cannot necessarily be loaded up to
the tire’s maximum load rating on the
tire sidewall. „Adverse safety consequenc-
es of overloading on handling
and stopping and on tires
Overloading could affect vehicle han-
dling, stopping distance, vehicle and
tire as shown in the following. This
could lead to an accident and possibly
result in severe personal injury. y Vehicle stability will deteriorate.
y Heavy and/or high-mounted loads
could increase the risk of rollover. y Stopping distance will increase.
y Brakes could overheat and fail.
y Suspension, bearings, axles and
other parts of the body could break or
experience accelerated wear that will
shorten vehicle life. y Tires could fail.
y Tread separation could occur.
y Tire could separate from its rim. „
Steps for Determining Cor-
rect Load Limit
1. Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXX pounds” on
your vehicle’s placard.
2. Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
3. Subtract the combined weight of
the driver and passengers from XXX
kilograms or XXX pounds.
4. The resulting figure equals the
available amount of cargo and lug-
gage load capacity. For example, if
the “XXX” amount equals 1,400 lbs
(635kg). and there will be five- 150 lbs
(68 kg) passengers in your vehicle,
the amount of available cargo and
luggage load capacity is 650 lbs.
(1,400 – 750 (5 u 150) = 650 lbs)
5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not safe-
ly exceed the available cargo and lug-
gage load capacity calculated in Step4.
6. If your vehicle will be towing a trail-
er, load from your trailer will be trans- ferred to your vehicle. Consult this
manual to determine how this reduc-
es the available cargo and luggage
load capacity of your vehicle.

Uniform tire quality grading
standards
This information indicates the relative
performance of passenger car tires in
the area of treadwear, traction, and
temperature resistance. This is to aid
the consumer in making an informed
choice in the purchase of tires.
Quality grades can be found where
applicable on the tire sidewall be-
tween tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Tem-
perature A
The quality grades apply to new pneu-
matic tires for use on passenger cars.
However, they do not apply to deep
tread, winter type snow tires, space-
saver or temporary use spare tires,
tires with nominal rim diameters of 12
inches or less, or to some limited pro-
duction tires.
All passenger car tires must confirm
to Federal Safety Requirements in
addition to these grades.„
Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the
tire when tested under controlled con-
ditions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half (1-1/2) times
as well on the government course as
a tire graded 100. The relative perfor-
mance of tires depends upon the ac-
tual conditions of their use, however,
and may depart significantly from the
norm due to variations in driving hab-
its, service practices and differences
in road characteristics and climate. „ Traction AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of as-
phalt and concrete. A tire marked C
may have poor traction performance.
„ Temperature A, B, C
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel. Sustained high tempera-
ture can cause the material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C corre-
sponds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standards No. 109. Grades B
and A represent higher levels of per-
formance on the laboratory test wheel
than the minimum required by law.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning, or
peak traction characteristics.
