Tire Information
404■Determining Compatibility of
Tire and Vehicle Load Capac -
itiesThe sum of four tires’ maximum
load ratings must exceed the
maximum loaded vehicle weight
(“GVWR”). In addition, sum of the
maximum load ratings of two front
tires and of two rear tires must
exceed each axle’s maximum
loaded capacity (“GVWR”). 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 certific ation label affixed
to the driver’s door.
The GVWR and front and rear
GAWRs are determined by not only
the maximum load rating of tires but
also loaded capacities of the
vehicle’s suspension, axles and
other parts of the body. Therefore, this means that the

vehicle cannot necessarily be
loaded up to the tire’s maximum
load rating on the tire sidewall.
■ Adverse Safety Conse -
quences of Overloading on
Handling and Stopping and
on TiresOverloading could affect vehicle
handling, stopping distance, vehicle
and tire as shown in the following.
This could lead to an accident and
possibly result in severe personal
injury.
 Vehicle stability will deteriorate.
 Heavy and/or high-mounted
loads could increase the risk of
rollover.
 Stopping distance will increase.
 Brakes could overheat and fail.
 Suspension, bearings, axles and
other parts of the body could break
or experience accelerated wear that
will shorten vehicle life.
 Tires could fail.
 Tread separation could occur. 
Tire could separate from its rim.
■ Steps for Determining
Correct Load Limit1. Locate the statement “The
combined weight of occupants and
cargo should never exceed XXX kg
or XXX lbs.” on your vehicle’s
placard.
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
XXX kg or XXX lbs.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the “
XXX
” amount equals
1,400 lbs (635 kg) and there will be
five 150 lbs (68 kg) passengers in
your vehicle, the amount of avail-
able cargo and luggage load
capacity is 650 lbs (1,400 − 750 (5 ×
150) = 650 lbs).
5. Determine the combined weight
of luggage and cargo being loaded

(98 RON) or higher .■Fuel octane rating▼ RON
This octane rating is the Research Octane Number.
▼ AKI
This octane rating is the average of the Research Octane and
Motor Octane numbers and is commonly referred to as the Anti
Knock Index (AKI).■ Limit of ethanol contentNo more than 15%■Fuel tank capacity13.2 US gal (50 liters, 11.0 Imp gal)■Engine oilAlways use the SUBARU approved engine oil. For further
details, please contact your SUBARU dealer.
If the approved engine oil is unav ailable, use the alternative
engine oil described as follows.
 API classification SN with the words “RESOURCE
CONSERVING”, SN PLUS with the words “RESOURCE
CONSERVING” or SP with the words “RESOURCE
CONSERVING” 
or ILSAC GF-5 or GF-6A, which can be identified with the
ILSAC certification ma rk (Starburst mark)
