Tire and Loading Information Label
Example Label
A vehicle specific Tire and Loading Information label is
attached to the center pillar (B-pillar) of your vehicle.
With the driver's door open, you will find the label
attached below the door lock post (striker). The tire and
loading information label shows the number of
occupant seating positions (A), and the maximum
vehicle capacity weight (B) in kilograms and pounds.
4-32
The Tire and Loading Information label also shows
the size of the original equipment tires (C) and
the recommended cold tire inflation pressures (D). For
more information on tires and inflation see Tires on
page 5-52 and Inflation - Tire Pressure on page 5-58.
There is also important loading information on the
vehicle Certification/Tire label. It tells you the Gross
Vehicle Weight Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for the front and rear axle.
See "Certification/Tire Label" later in this section.
Steps for Determining Correct Load Limit
1. Locate the statement "The combined weight of
occupants and cargo should never exceed
XXX kg or 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 luggage load capacity. For example, if
the "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 (5 x 150) = 650 lbs).
