Tire markings1, Tire widthThis three digit number gives the width in
millimeters of the tire from sidewall edge to
sidewall edge.2, Aspect ratioThis two digit number, known as the aspect
ratio or profile, gives the sidewall height as a
percentage of the tread width. So, if the tread
width is 205 mm, and the aspect ratio is 50,
the sidewall height will be 102 mm.3, Tire constructionR indicates that the tire is of Radial ply
construction.4, Wheel diameterThis two digit number is the diameter of the
wheel rim in inches.5, Load indexThis two or three digit number is the tire's load
index. It is a measurement of how much
weight each tire can support. This number is
not always shown.6, Speed ratingThe speed rating, when stated, denotes the
maximum speed at which the tire should be
used for extended periods. The ratings range
from 99 mph to 186 mph. These ratings are
listed in the following table.

Wheels and tires11-6Technical specifications7, U.S DOT Tire Identification Number
(TIN)This begins with the letters DOT and
indicates that the tire meets all federal
standards. The next two numbers or letters
are the plant code where it was
manufactured, and the last four numbers
represent the week and year the tire was
built. For example, the numbers 1706 means
the 17th week of 2006. The other numbers
are marketing codes used at the
manufacturer's discretion. This information
can be used to contact consumers if a tire
defect requires a recall.8, Maximum permissible inflation
pressureThe maximum inflation pressure for the tire.
This pressure should not be used for normal
driving.
9, Treadwear gradeThis number indicates the tire's wear rate.
The higher the treadwear number is, the
longer it should take for the tread to wear
down. A tire rated at 400 for example, will
last twice as long as a tire rated at 200.10, Traction gradeThis letter indicates a tire's ability to stop on
wet pavement. A higher graded tire should
allow you to stop your vehicle on wet roads in
a shorter distance than a tire with a lower
grade.
Traction is graded from highest to lowest as
AA, A, B, and C.11, Temperature gradeHeat resistance grading. The tires resistance
to heat is grade A, B, or C, with A indicating
the greatest resistance to heat. This grading
is provided for a correctly inflated tire, which
is being used within its speed and loading
limits.12, Tire composition and materialsThe number of plies in both the tread area,
and the sidewall area, indicates how many
l aye rs o f ru bb e r co ate d m ate ri al m ake u p t h e
structure of the tire. Information is also
provided on the type of materials used.

Technical specifications
Tire placard/labelThe tire information label on the pillar behind
the driver’s door contains the following
information:
• The maximum number of occupants for
the vehicle.
• The vehicle capacity weight, which
includes the weight of the driver,
passengers and cargo.
• The size of the tires with which the
vehicle was originally equipped.
• Cold inflation pressures for the front and
rear tires.
Note: The label must not be changed, even if
different wheels are fitted at a later stage.Steps for determining correct load
limit
WARNING: Do not exceed the vehicle
capacity weight (the total weight of
driver, passenger and cargo) given.
S
WARNING: Overloading the vehicle will
have an adverse affect on braking and
handling characteristics, which could
compromise your safety.
S
1. Locate the statement “The combined weight of occupants and cargo should
neve r exce e d 2 50 kg or 5 51 l bs ” as s h ow n
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 250 kg or 551
lbs (weight given on placard).
4. The resulting figure equals the available amount of cargo and luggage load
capacity. For example, if there will be two
150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 251 lbs: (551 - 300 (2 x
150) = 251 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. Your vehicle should never be used to tow a trailer.
The number and weight of passengers will
affect the cargo and luggage load capacity. In
the example above, the cargo and luggage
load capacity is 251 lbs. However, if only one
occupant is in the vehicle, the luggage load
capacity will increase. If the vehicle carries
one 150 lb person, the luggage load capacity
will increase to 401 lbs (551 - 150 = 401 lbs).
Note: If the passengers weigh more, the
luggage load capacity will decrease.Uniform tire quality gradingThe following information relates to the tire
grading system developed by the National
Highway Traffic Safety Administration
(NHTSA) which will grade tires by tread wear,
traction and temperature performance.
Note: Tires that have deep tread, and winter
tires, are exempt from these marking
requirements.
Quality grades, where applicable, can be
found on the tire sidewall between the tread
shoulder and maximum section width. For
example:TREADWEAR 180
