Determining Compatibility Of Tire And Vehicle Load Capacities - Subaru 2006 Legacy Owner's Manual

Consumer information and Reporting safety defects
Available Load Capacity
= 800 lbs (363 kg) 628 lbs (285 kg)
(Total weight)
(Vehicle
capacity weight)
= 172 lbs (78 kg)
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 occupants to
three), and a child restraint system
weighing 11 lbs (5 kg) is installed in
the vehicle for the child to use, the cal-
culations are as follows:
1. Calculate the total weight.
Total weight
= 165 lbs (75 kg) + 143 lbs (65 kg)
(Occupant)
+ 40 lbs (18 kg)
(Occupant)
+ 11 lbs (5 kg)
(Child restraint)
+ 22 lbs (10 kg) + 176 lbs (80 kg)
(Trailer hitch)
= 822 lbs (373 kg)
2. Calculate the available load capac-
ity.
Available Load Capacity
D00114
= 800 lbs (363 kg)
(Vehicle
capacity weight)
= 22 lbs ( 10 kg)
3. The total weight now exceeds the
capacity weight by 22 lbs (10 kg), so
the cargo weight must be reduced by
22 lbs (10 kg) or more.
The sum of four tires' maximum load
ratings must exceed the maximum
loaded vehicle weight ("GVWR"). In
addition, sum of the maximum load
+ 265 lbs (120 kg)
ratings of two front tires and of two
rear tires must exceed each axle's
(Cargo)
maximum loaded capacity ("GAWR").
Original equipment tires are designed
(Tongue load)
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
(GAWR). The GVWR and each axle's
GAWR are shown on the vehicle cer-
822 lbs (373 kg)
tification label affixed to the driver's
(Total weight)
door.
The GVWR and front and rear
GAWRs are determined by not only
the maximum load rating of tires but

tire and vehicle load capaci-
