Vehicle capacity weight of the vehicle is 800 lbs
(363 kg), which is indicated on the vehicle plac-
ard with the statement “The combined weight of
occupants and cargo should never exceed 363
kg or 800 lbs”.
For example, if the vehicle has one occupant
weighing 154 lbs (70 kg) plus cargo weighing
551 lbs (250 kg).
1. Calculate the total weight.
2. Calculate the available load capacity by sub-
tracting the total weight from the vehicle capacity
weight of 800 lbs (363 kg).
3. The result of step 2 shows that a further 95 lbs
(43 kg) of cargo can be carried.
Example 1B
For example, if a person weighing 176 lbs (80
kg) now enters the same vehicle (bringing the
Total weight = 154 lbs (70 kg) + 551 lbs (250 kg) =
705 lbs (320 kg)(Occupant) (Cargo)
Available Load Capacity = 800 lbs (363 kg) – 705 lbs (320 kg) =
95 lbs (43 kg) (Vehicle
capacity weight) (Total weight)

number of occupants to two), the calculations
are as follows:
1. Calculate the total weight.
2. Calculate the available load capacity.
3. The total weight now exceeds the capacity
weight by 81 lbs (37 kg), so the cargo weight
must be reduced by 81 lbs (37 kg) or more. Example 2A
Vehicle capacity weight of the vehicle is 800 lbs
(363 kg), which is indicated on the vehicle plac-
ard with the statement “The combined weight of
occupants and cargo should never exceed 363
kg or 800 lbs”.
For example, the vehicle has one occupant
weighing 165 lbs (75 kg) plus cargo weighing
265 lbs (120 kg). In addition, the vehicle is fitted
with a trailer hitch weighing 22 lbs (10 kg), towhich is attached a trailer weighing 1764 lbs
(800kg). 10% of the trailer weight is applied to
Total weight = 154 lbs (70 kg) + 176 lbs (80 kg) + 551 lbs (250 kg) =
881 lbs (400 kg) (Occupant)

Available Load Capacity
= 800 lbs (363 kg) – 881 lbs (400 kg) = – 81 lbs (–37 kg) (Vehicle

the trailer tongue (i.e. Tongue load = 176 lbs (80 kg)).
1. Calculate the total weight.
2. Calculate the available load capacity.
3. The result of step 2 shows that a further 172
lbs (78 kg) of cargo can be carried.
Example 2B
For example, if a person weighing 143 lbs (65
kg) and a child weighing 40 lbs (18 kg) now enter
the same vehicle (bringing the number of occu-
pants to three), and a child restraint system
weighing 11 lbs (5 kg) is installed in the vehicle
for the child to use, the calculations are as fol-
lows:
1. Calculate the total weight.
Total weight
= 165 lbs (75 kg) + 265 lbs (120 kg)
+ 22 lbs (10 kg) + 176 lbs (80 kg) =
628 lbs (285 kg)(Occupant) (Cargo)
(Trailer hitch) (Tongue load)
Available Load Capacity
= 800 lbs (363 kg) – 628 lbs (285 kg) =
172 lbs (78 kg) (Vehicle
capacity weight) (Total weight)

2. Calculate the available load capacity.
3. The total weight now exceeds the capacity
weight by 22 lbs (10 kg), so the cargo weight
must be reduced by 22 lbs (10kg) or more. „
Determining compatibility of tire and
vehicle load capacities
The sum of four tires’ maximum load ratings
must exceed the maximum loaded vehicle
weight (“GVWR”). In addition, sum of the maxi-
mum load ratings of two front tires and of two
rear tires must exceed each axle’s maximum
loaded capacity (“GAWR”). Original equipment
tires are designed to fulfill those conditions.
The maximum loaded vehicle weight is referred
to Gross Vehicle Weight Rating (GVWR). And
each axle’s maximum loaded capacity is referred
to Gross Axle Weight Rating (GAWR). The
GVWR and each axle’s GAWR are shown on the
vehicle certification label affixed to the driver’s
door.
The GVWR and front and rear GAWRs are de-
termined by not only the maximum load rating of
tires but also loaded capacities of the vehicle’s
suspension, axles and other body parts.
Therefore, this means that the vehicle cannot
necessarily be loaded up to the tire’s maximum
load rating on the tire sidewall.
Total weight = 165 lbs (75 kg) + 143 lbs (65 kg) + 40 lbs (18 kg)
+ 11 lbs (5 kg) + 265 lbs (120 kg) + 22 lbs (10 kg) + 176 lbs (80 kg) = 822 lbs (373 kg) (Occupant)

= 800 lbs (363 kg) – 882 lbs (373 kg) = – 22 lbs (–10 kg) (Vehicle
