Determining the Correct Load Limit
1. Locate the statement 'The combined weight of occupants
and cargo should never exceed XXX kg or XXX lb' on the
vehicle's tire label.
2. Determine the combined weight of the driver and
passengers that will be riding in the vehicle.
3. Subtract the combined weight of the driver and passengers
from XXX kg or XXX lb.
4. The resulting figure equals the available amount of cargo
and luggage load capacity. For example, if the 'XXX' amount
equals 1250 lb and there will be four 150 lb passengers in
the vehicle, the amount of available cargo and luggage load
capacity is 650lb (1250–600 (4x150) = 650 lb).
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.
Maximum Permissible Inflation Pressure
The maximum permissible inflation pressure is the tire
manufacturer's maximum permissible pressure and / or the
pressure at which the maximum load can be carried by the tire.
This pressure is normally higher than the manufacturer's
recommended cold inflation pressure which can be found on the
Safety Compliance Certification Label or Tire Label.
The cold inflation pressure should never be set lower than the
recommended pressure on the Safety Compliance Certification
Label or Tire Label.
The recommended cold inflation tire pressures for this vehicle
can also be found in handbook (Refer to 'Tire Pressures', page
12.16).
