Steps for Determining Correct Load Limit
1. Locate the "Maximum Load" amount
printed on the Tire and Loading Information
label.
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 the maximum load
amount, shown in pounds and kilograms.
4. The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the "maximum load" 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).
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.
