Maintenance and service/Tires and wheels

from controllability, ride comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incorrect body-to-tire clearances and inappropriately 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 equipment.
For safe vehicle operation, SUBARU
recommends replacing all four tires at
the same time.

WARNING
. When replacing or installing
tire(s), all four tires must be the
same for the following items.
(a) Size
(b) Circumference
(c) Speed symbol
(d) Load index
(e) Construction
(f) Manufacturer
(g) Brand (tread pattern)
(h) Degrees of wear

For items (a) to (d), you must
obey the specification that is
printed on the tire placard. The
tire placard is located on the
driver’s door pillar.
If all four tires are not the same in
items (a) to (h), there is a possibility that it may lead to serious
mechanical damage to the drive
train of your car and affect the
following factors.
— Ride
— Handling
— Braking
— Speedometer/Odometer
calibration
— 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.

& Wheel replacement
When replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equipment. Replacement wheels are available
from SUBARU dealers.

WARNING
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper operation and may cause the tires to rub
against the wheel well housing during turns. The resulting loss of
vehicle control could lead to an
accident.

NOTE
When any of the wheels are removed
and replaced for tire rotation or to
change a flat tire, always check the
tight
