Tires and Wheels
35811-21. Tires and Wheels■Types of TiresYou should be familiar with type of tires
present on your vehicle.
▼ Summer tires
The factory-installed tires on your new
vehicle are summer tires.
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-
covered or icy roads.
If you drive your vehicle on snow-covered
or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to
replace all four tires.
▼ All season tires
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road
conditions. However all season tires do
not offer as much traction performance as
winter (snow) tires in heavy or loose snow
or on icy roads. All season tires are identified by “ALL

SEASON” and/or “M+S” (Mud & Snow) on
the tire sidewall.
▼ Winter (snow) tires
Winter tires are best suited for driving on
snow-covered and icy roads. However
winter tires do not perform as well as
summer tires and all season tires on roads
other than snow-covered and icy roads.
NOTEIf the tread wears down below 0.16 in.
(4mm) on snow tires the effectiveness
of snow tires is lost.
▼ Low profile tires
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard tires. Be sure to
use snow tires or tire chains on snowy
and/or icy roads and drive carefully at a
speed appropriate for road and weather
conditions.NOTELow profile tires may cause greater
damage than usual to the wheel when
receiving impact from the road sur-
face. Therefore pay attention to the fol-
lowing: 
Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
 Avoid pot holes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
■ Tire Pressure Monitoring
System (TPMS) (If Equipped)The tire pressure monitoring system
provides the driver with a warning
message by sending a signal from a
sensor that is installed in each wheel
when tire pressure is severely low. The
tire pressure monitoring system will acti-
vate only when the vehicle is driven. Also,
this system may not react immediately to
a sudden drop in tire pressure (for
example, a blow-out caused by running
over a sharp object).
If you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to illuminate. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to pres-
sures higher than those shown on the tire
inflation pressure label. Specifically,
inflate them by an extra 1 psi (6.9 kPa,
0.07 kgf/cm
2) for every difference of 10°F

– CONTINUED –
– A tire goes flat repeatedly or
cannot be properly repaired
due to the size or location of a
cut or other damage
If you are not su re, consult with
your SUBARU dealer.
 Any tires over 6 years old must
be checked by a qualified techni-
cian even if they have seldom or
never been used or damage is
not obvious.
■ Tire Pressures and WearMaintaining the correct tire pres-
sures helps to maximize the tires’
service lives and is essential for
good running performance. Check
and, if necessary, adjust the pres-
sure of each tire and the spare (if
equipped) at least once a month
and before any long journey. Tire inflation pressure label
Check the tire pressures when the
tires are cold. Use a pressure gauge
to adjust the tire pressures to the
values shown on the tire inflation
pressure label. The tire inflation
pressure label is located on the
center pillar on the driver’s side.
Driving even a short distance
warms up the tires and increases
the tire pressures. Also, the tire
pressures are affected by the
outside temperature. It is best to
check tire pressure outdoors before
driving the vehicle.
When a tire becomes warm, the air
inside it expands, causing the tire pressure to increase. Be careful not

to mistakenly release air from a
warm tire to reduce its pressure.
NOTE The air pressure in a tire
increases by approximately 4.3
psi (30 kPa, 0.3 kgf/cm
2) when the
tire becomes warm.
 The tires are considered cold
when the vehicle has been
parked for at least 3 hours or has
been driven less than 1 mile (1.6
km).
Incorrect tire pressures detract from
controllability and ride comfort, and
they cause the tires to wear abnor-
mally.
 Correctly inflated tires (tread
worn evenly)
B02109
WARNING
Do not let air out of warm tires
to adjust pressure. Doing so
will result in low tire pressure.

After driving approximately 600
miles (1,000 km), check the wheel
nuts again and retighten any nut
that has become loose.■ Tire ReplacementThe wheels and tires are important and
integral parts of your vehicle’s design;
they cannot be changed arbitrarily. The
tires fitted as standard equipment are opti-
mally matched to the characteristics of the
vehicle and were sele cted to give the best
possible combination of running perfor-
mance, ride comfort, and service life. It is
essential for every tire to have a size and
construction matching those shown on the
tire inflation pressure label and to have a
speed symbol and load index matching
those shown on the tire inflation pressure
label.
Using tires of a non-specified size detracts
from controllability, ride comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incor-
rect body-to-tire clearances and inappro-
priately changes the vehicle’s ground
clearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern),
construction, and size. You are advised to
replace the tires with new ones that are identical to those fitted as standard equip-
ment.
For safe vehicle operation, SUBARU

recommends replacing all four tires at the
same time.
■ Wheel ReplacementWhen replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available
from SUBARU dealers.
WARNING
 When replacing or installing
tire(s), all four tires must be the
same for the following items.
(a) Size(b) Speed symbol(c) Load index(d) Circumference(e) Construction(f) Manufacturer(g) Brand (tread pattern)(h) Degrees of wearFor items (a) to (c), you must
obey the specification that is
printed on the tire inflation pres-
sure label. The tire inflation pres-
sure label is located on the
driver’s center pillar.
If all four tires are not the same in
items (a) to (h), serious mechani-
cal damage could be caused to
the drivetrain of the car, and
affect the followings.-Ride-Handling-Braking- Speedometer/Odometer cali- bration- Clearance between the body
and the tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
 Use only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires.
Doing so can dangerously reduce
controllability, resulting in an
accident.

(6) Load Index: A numerical code
which specifies the maximum load a
tire can carry at the speed indicated
by its speed symbol, at maximum
inflation pressure.
For example, “
91” means 1,356 lbs
(615 kg), “90” means 1,323 lbs (600 kg),
“89
” means 1,279 lbs (580 kg)
(7) Speed Rating: An alphabetical
system describing a tire’s capability
to travel at established and prede-
termined speeds.
For example, “
V” means 149 mph
(240 km/h)
▼ Tire Identification Number
(TIN)
Tire Identification Number (TIN) is
marked on the intended outboard
sidewall. The TIN is composed of
four groups. Here is a brief review of
the TIN with a breakdown of its indi-
vidual elements. (1) DOT symbol*
(2) Manufacturer’s Identification
Mark
(3) Tire Size Code
(4) Tire Type Code
(5) Date of Manufacture
The first two figures identify the

week, starting with “
01” to represent
the first full week of the calendar
year; the second two figures repre-
sent the year. For example, 0101
means the 1st week of 2001.
*: The DOT symbol certifies that the
tire conforms to applicable
Federal Motor Vehicle Safety
Standards.
▼ Other markings
The following makings are also
placed on the sidewall.
WARNING
Load indices apply only to the
tire, not to the vehicle. Putting
a load rated tire on any vehicle
does not mean the vehicle can
be loaded up to the tire’s rated
load.
WARNING
 Speed ratings apply only to
the tire, not to the vehicle.
Putting a speed rated tire on
any vehicle does not mean
the vehicle can be operated
at the tire’s rated speed. The speed rating is void if
the tires are worn out,
damaged, repaired,
retreaded, or otherwise
altered from their original
condition. If tires are
repaired, retreaded, or other-
wise altered, they may not be
suitable for original equip-
ment tire designed loads and
speeds.

The vehicle placard shows original
tire size, recommended cold tire
inflation pressure on each tire at
maximum loaded vehicle weight,
seating capacity and loading infor-
mation.▼ Adverse safety consequences
of under-inflation
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to
rapidly become hot. A sharp
increase in temperature could
cause tread separation, and failure
of the tire(s). Possible resulting loss
of vehicle control could lead to an
accident.
▼ Measuring and adjusting air
pressure to achieve proper
inflation
Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and
before any long journey. Check the
tire pressures when the tires are
cold. Use a pressure gauge to adjust the tire pressures to the

specific values. Driving even a short
distance warms up the tires and
increases the tire pressures. Also,
the tire pressures are affected by
the outside temperature. It is best to
check tire pressure outdoors before
driving the vehicle. When a tire
becomes warm, t he air inside it
expands, causing the tire pressure
to increase. Be careful not to
mistakenly release air from a warm
tire to reduce its pressure.
■ Glossary of Tire TerminologyAccessory weight
The combined weight (in excess of
those standard items which may be
replaced) of automatic transmis-
sion, power steering, power brakes,
power windows, power seats, radio,
and heater, to the extent that these
items are available as factory-
installed equipment (whether
installed or not).
 Bead
The part of the tire that is made of
steel wires, wrapped or reinforced by ply cords and that is shaped to fit

the rim.
 Bead separation
A breakdown of the bond between
components in the bead.
 Bias ply tire
A pneumatic tire in which the ply
cords that extend to the beads are
laid at alternate an gles substantially
less than 90 degrees to the
centerline of the tread.
 Carcass
The tire structure, except tread and
sidewall rubber which, when
inflated, bears the load.
 Chunking
The breaking away of pieces of the
tread or sidewall.
 Cold tire pressure
The pressure in a tire that has been
driven less than 1 mile or has been
standing for three hours or more.
 Cord
The strands forming the plies in the
tire.
