NOTE:
P (Passenger) — Metric tire sizing is based on US design
standards. P-Metric tires have the letter “P” molded
into the sidewall preceding the size designation.
Example: P215/65R15 95H.
 European — Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with the section width. The letter "P" is absent from this tire size
designation. Example: 215/65R15 96H.
 LT (Light Truck) — Metric tire sizing is based on US
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preceding
the size designation. Example: LT235/85R16.
 Temporary spare tires are designed for temporary
emergency use only. Temporary high pressure compact spare tires have the letter “T” or “S” molded into the
sidewall preceding the size designation. Example:

 High flotation tire sizing is based on US design stan -
dards and it begins with the tire diameter molded into
the sidewall. Example: 31x10.5 R15 LT.

Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire; however, the date code may only be on one side. Tires with white sidewalls will have the full TIN, including the date code, located
on the white sidewall side of the tire. Look for the TIN on the outboard side of black sidewall tires as mounted on the vehicle. If the TIN is not found on the outboard side, then you will
find it on the inboard side of the tire.Service Description:
95
= Load Index
 A numerical code associated with the maximum load a tire can carry
H = Speed Symbol
 A symbol indicating the range of speeds at which a tire can carry a load corresponding to its load index under certain operating conditions
 The maximum speed corresponding to the speed symbol should only be achieved under specified operating conditions (i.e., tire pressure, vehicle loading, road conditions, and
posted speed limits)
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL) tire:
 XL = Extra load (or reinforced) tire, or
 LL = Light load tire or
 C, D, E, F, G = Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load – Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure – Maximum pressure indicates the maximum permissible cold tire inflation pressure for this tire
EXAMPLE:
EXAMPLE:
DOT MA L9 ABCD 0301
DOT = Department of Transportation
 This symbol certifies that the tire is in compliance with the US Department of Transportation tire safety standards and is approved for highway use
MA = Code representing the tire manufacturing location (two digits)
L9 = Code representing the tire size (two digits)
ABCD = Code used by the tire manufacturer (one to four digits)

Tire Terminology And Definitions
03 = Number representing the week in which the tire was manufactured (two digits)
 03 means the 3rd week
01 = Number representing the year in which the tire was manufactured (two digits)
 01 means the year 2001
 Prior to July 2000, tire manufacturers were only required to have one number to represent the year in which the tire was manufactured. Example: 031 could represent the 3rd
week of 1981 or 1991
Term Definition
B-pillarThe vehicle B-pillar is the structural member of the body located behind the front door.
Cold Tire Inflation Pressure Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km) after sitting for a minimum of three hours. Inflation
pressure is measured in units of psi (pounds per square inch) or kPa (kilopascals).
Maximum Inflation Pressure The maximum inflation pressure is the maximum permissible cold tire inflation pressure for this tire. The
maximum inflation pressure is molded into the sidewall.
Recommended Cold Tire Inflation Pressure Vehicle manufacturer's recommended cold tire inflation pressure as shown on the tire placard.
Tire Placard A label permanently attached to the vehicle describing the vehicle’s loading capacity, the original
equipment tire sizes and the recommended cold tire inflation pressures.

Tire Loading And Tire Pressure
NOTE:The proper cold tire inflation pressure is listed on the
driver’s side B-pillar or the rear edge of the driver's side
door.
Check the inflation pressure of each tire, including the
spare tire (if equipped), at least monthly and inflate to the
recommended pressure for your vehicle.

Tire And Loading Information Placard

Tire And Loading Information Placard

This placard tells you important information about the:

1. Number of people that can be carried in the vehicle.

2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear, and
spare tires.
Loading
The vehicle maximum load on the tire must not exceed the
load carrying capacity of the tire on your vehicle. You will
not exceed the tire's load carrying capacity if you adhere to
the loading conditions, tire size, and cold tire inflation
pressures specified on the Tire And Loading Information
Placard
Úpage 169.
NOTE:Under a maximum loaded vehicle condition, Gross Axle
Weight Rating (GAWR) for the front and rear axles must
not be exceeded.

350SERVICING AND MAINTENANCE
For further information on GAWR, vehicle loading, and
trailer towing Úpage 169.
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX kg or XXX
lbs” on the Tire And Loading Information Placard. The
combined weight of occupants, cargo/luggage and trailer
tongue weight (if applicable) should never exceed the
weight referenced here.
Steps For Determining Correct Load Limit—
(1) Locate the statement “The combined
weight of occupants and cargo should
never exceed XXX kg or XXX lbs.” 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 kg or
XXX lbs. (4) The resulting figure equals the
available amount of cargo and luggage
load capacity. For example, if “XXX”
amount equals 1400 lbs. and there will
be five 150 lb passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400-750 (5x150) = 650 lbs.)
(5) 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 calculated in Step 4.
(6) 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 vehicle.
Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg and there will
be five 68 kg passengers in your vehicle, the amount of
available cargo and luggage load capacity is 295 kg
(635-340 (5x68) = 295 kg) as shown in step 4.
NOTE:

If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. The following
table shows examples on how to calculate total load,
cargo/luggage, and towing capacities of your vehicle
with varying seating configurations and number and
size of occupants. This table is for illustration purposes
only and may not be accurate for the seating and load
carry capacity of your vehicle.
 For the following example, the combined weight of
occupants and cargo should never exceed 865 lb (392
kg).
