Consumer information and Reporting safety defects

For U.S.A.

The following information has been

compiled according to Code of

Federal Regulations “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 markings

can provide you with useful infor-

mation on the tire.

! Tire size

Your vehicle comes equipped with

P-Metric tire size. It is important to

understand the sizing system in

selecting the proper tire for your

vehicle. Here is a brief review of the

tire sizing system with a breakdown

of its individual 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 dimen-

sional information about the tire

size.

Example:

(1) P = Certain tire type used on

light duty vehicles such as passen-

ger cars
(2) Section Width in millimeters
(3) Aspect Ratio (= section height
7 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

designation is its load index. Sec-

ond, the letter designation indicates

the tire’s speed rating.

Example:

(6) Load Index: A numerical code

which specifies the maximum load

a tire can carry at the speed

indicated by its speed symbol, at

maximum inflation pressure.
For example, “104” means 1,984

lbs (900 kg), “100” means 1,764 lbs

(800 kg), “90” means 1,323 lbs (600

kg).

WARNING

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.

(7) Speed Rating: An alphabetical

system describing a tire’s capability

to travel at established and prede-

termined speeds.
For example, “H” means 130 mph

(210 km/h).

WARNING

Speed ratings apply only to

the tire, not to the vehicle.

Putting a speed rated tire on

any vehicle does not mean

the vehicle can be operated

at the tire’s rated speed.

The speed rating is void if

the tires are worn out, da-

maged, repaired, retreaded,

or otherwise altered from

their original condition. If

tires are repaired, re-

treaded, or otherwise al-

tered, they may not be sui-

table for original equipment

tire designed loads and

speeds.

! 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 repre-

sent 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 pres-

sure to which this tire may be

inflated. For example, “300 kPa

(44 PSI) MAX. PRESS”.

Consumer information and Reporting safety defects

13-3

Consumer information and Reporting safety defects

! Maximum load rating

The load rating at the maximum

permissible weight load for this tire.

For example, “MAX. LOAD 730 kg

(1609 LBS) @ 300 kPa (44 PSI)

MAX. PRESS.”

WARNING

Maximum load rating applies

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.

! Construction type

Applicable construction of this tire.
For example, “TUBELESS STEEL

BELTED RADIAL”

! Construction

The generic name of each cord

material used in the plies (both

sidewall and tread area) of this tire.
For example, “PLIES: TREAD 2

STEEL + 2 POLYESTER + 1

NYLON SIDEWALL 2 POLYE-

STER”

! Uniform Tire Quality Grading

(UTQG)

For details, refer to “Uniform tire

quality grading standards” F13-14

& Recommended tire inflation

pressure

! Recommended cold tire infla-

tion pressure

For the recommended cold tire

inflation pressure for your vehicle’s

tires, refer to “Tires” F12-8

! 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

inflation pressure on each tire at

maximum loaded vehicle weight,

seating capacity and loading infor-

mation.

! 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 in-

crease in temperature could cause

tread separation, and failure of the

tire(s). Possible resulting loss of

vehicle control could lead to an

accident.

! Measuring and adjusting air

pressure to achieve proper in-
flation

Check and, if necessary, adjust the

pressure of each tire (including the

spare) at least once a month and

before 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 temperature. It is

best to check tire pressure out-

doors before driving the vehicle.

When a tire becomes warm, the air

inside it expands, causing the tire

pressure to increase. Be careful not

to mistakenly release air from a

warm tire to reduce its pressure.

& 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 visi-

ble. When a tire’s tread wear

indicator becomes visible, the tire

is worn beyond the acceptable limit

and must be replaced immediately.

With a tire in this condition, driving

at even low speeds in wet weather

can cause the vehicle to hydro-

plane. Possible resulting loss of

vehicle control can lead to an

accident.

Consumer information and Reporting safety defects

13-10

Consumer information and Reporting safety defects

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 (12,000 km).

For information about the tire rota-

tion order, refer to “Tire rotation”

F11-26

Replace any damaged or

unevenly worn tires at the time of

rotation. After tire rotation, adjust

the tire pressures and make sure

the wheel nuts are correctly tigh-

tened. For information about the

tightening torque and tightening

sequence for the wheel nuts, refer

to “Flat tires” F9-6

& Vehicle load limit – how to

determine

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

seating capacity of your vehicle.
The total load capacity includes the

total weight of driver and all pas-

sengers 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 calculated 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 information about vehicle load-

ing, refer to “Loading your vehicle”

F8-12

For information about towing capa-

city and weight limits, refer to
“Trailer towing” F8-21

! Calculating total and load ca-

pacities varying seating con-

figurations

Calculate the available load capa-

city as shown in the following

examples.

Example 1A

Vehicle capacity weight of the

vehicle is 1,157 lbs (525 kg), which

is indicated on the vehicle placard

with the statement “The combined

weight of occupants and cargo

should never exceed 525 kg or

1,157 lbs”.

For example, if the vehicle has one

occupant weighing 154 lbs (70 kg)

plus cargo weighing 882 lbs (400

kg).

Calculate the total weight.

Calculate the available load ca-

pacity by subtracting the total

weight from the vehicle capacity

weight of 1,157 lbs (525 kg).

The result of step 2 shows that a

further 121 lbs (55 kg) of cargo can

be carried.

Example 1B

For example, if a person weighing

176 lbs (80 kg) now enters the

same vehicle (bringing the number

of occupants to two), the calcula-

tions are as follows.

Calculate the total weight.

Calculate the available load ca-

pacity.

The total weight now exceeds

the capacity weight by 55 lbs (25

kg), so the cargo weight must be

reduced by 55 lbs (25 kg) or more.

Example 2A

Vehicle capacity weight of the

Consumer information and Reporting safety defects

Consumer information and Reporting safety defects

vehicle is 1,157 lbs (525 kg), which

is indicated on the vehicle placard

with the statement “The combined

weight of occupants and cargo

should never exceed 525 kg or

1,157 lbs”.
For example, the vehicle has one

occupant weighing 165 lbs (75 kg)

plus cargo weighing 705 lbs (320

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)).

Calculate the total weight.

Calculate the available load ca-

pacity.

The result of step 2 shows that a

further 88 lbs (40 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 in the vehicle for the

child to use, the calculations are as

follows.

Calculate the total weight.

Calculate the available load ca-

pacity.

The total weight now exceeds

the capacity weight by 105 lbs (48

kg), so the cargo weight must be

reduced by 105 lbs (48 kg) or more.

& Determining compatibility of

tire and vehicle load capaci-

ties

The sum of four tires’ maximum

load ratings must exceed the max-

imum 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 Rat-

ing (GAWR). The GVWR and each

axle’s GAWR are shown on the

vehicle certification 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 vehi-

cle’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 conse-

quences of overloading on

handling and stopping and

on tires

Overloading could affect vehicle

handling, stopping distance, vehicle

and tire as shown in the following.

This could lead to an accident and

possibly result in severe personal

injury.

Vehicle stability will deteriorate.

Heavy and/or high-mounted

loads could increase the risk of

rollover.

Stopping distance will increase.

Brakes could overheat and fail.

Suspension, bearings, axles and

other parts of the body could break

or experience accelerated wear

that will shorten vehicle life.

Tires could fail.

Tread separation could occur.

Tire could separate from its rim.

& Steps for Determining Cor-

rect Load Limit

Locate the statement “The com-

bined weight of occupants and

cargo should never exceed XXX

kg or XXX lbs.” on your vehicle’s

placard.

Determine the combined weight

of the driver and passengers that

will be riding in your vehicle.

Subtract the combined weight of

the driver and passengers from

Consumer information and Reporting safety defects

13-13

– CONTINUED –

13-14

Consumer information and Reporting safety defects

XXX kg or XXX lbs.

The resulting figure equals the

available amount of cargo and

luggage load capacity. For exam-

ple, if the “XXX” amount equals

1,400 lbs (635 kg) and there will be

five- 150 lbs (68 kg) passengers in

your vehicle, the amount of avail-

able cargo and luggage load capa-

city is 650 lbs. (1,400 − 750 (5 6

150) = 650 lbs).

Determine the combined weight

of luggage and cargo being loaded

on the vehicle. That weight may not

safely exceed the available cargo

and luggage load capacity calcu-

lated in Step 4.

If your vehicle will be towing a

trailer, load from your trailer will be

transferred to your vehicle. Consult

this manual to determine how this

reduces the available cargo and

luggage load capacity of your ve-

hicle.

Uniform tire quality grading

standards

This information indicates the rela-

tive performance of passenger car

tires in the area of treadwear,

traction, and temperature resis-

tance. 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 maxi-

mum section width. For example:

Treadwear 200 Traction AA Tem-
perature A

The quality grades apply to new

pneumatic tires for use on passen-

ger cars. However, they do not

apply to deep tread, winter type

snow tires, space-saver or tempor-

ary use spare tires, tires with

nominal rim diameters of 12 inches

or less, or to some limited produc-

tion tires.

All passenger car tires must con-

form to Federal Safety Require-

ments in addition to these grades.

& Treadwear

The treadwear grade is a compara-

tive rating based on the wear rate of

the tire when tested under con-

trolled conditions 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 govern-

ment course as a tire graded 100.

The relative performance of tires

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.

& 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 spe-

cified government test surfaces of

asphalt and concrete. A tire marked

C may have poor traction perfor-

mance.

WARNING

The traction grade assigned to

this tire is based on straight-

ahead braking traction tests,

and does not include accel-

eration, cornering, hydroplan-

ing, or peak traction charac-

teristics.

& 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 con-

ditions on a specified indoor labora-

tory test wheel. Sustained high

temperature 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 corresponds to a level of

performance which all passenger

car tires must meet under the

Federal Motor Vehicle Safety Stan-

dards No. 109. Grades B and A

represent higher levels of perfor-

mance on the laboratory test wheel

than the minimum required by law.

WARNING

The temperature grade for this

tire is established for a tire

that is properly inflated and

not overloaded. Excessive

speed, underinflation, or ex-

cessive loading, either sepa-

rately or in combination, can

cause heat buildup and possi-

ble tire failure.
