Determining Compatibility Of Tire And Vehicle Load Capacities - Subaru 2004 Legacy Owner's Manual

Total weight
= 165 lbs (75 kg) + 143 lbs (65 kg) + 40 lbs (18 kg)
(Occupant)
+ 11 lbs (5 kg) + 265 lbs (120 kg)
(Child restraint) (Cargo)
+ 22 lbs (10 kg) + 176 lbs (80 kg)
(Trailer hitch) (Tongue load)
= 822 lbs (373 kg)
2. Calculate the available load capacity.
Available Load Capacity
= 800 lbs (363 kg) – 882 lbs (373 kg)
(Vehicle (Total weight)
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 (10kg) or more.
Consumer information and Reporting safety defects
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.
