check the wheel nuts again and retighten any nut that has become loose. Tire replacement
The 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 optimally matched to the characteris-
tics of the vehicle and were selected to give the best
possible combination of running performance, ride
comfort, and service life. It is essential for every tireto have a size and construction matching those
shown on the tire placard and to have a speed sym-
bol and load index matching those shown on the tire
placard.
Using tires of a non-specified size detracts 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 clear-
ance.
All four tires must be the same in terms of manufac-
turer, 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. NOTE Unidirectional tires: Some tires have a specified direction of rotation. A tire of this type has an ar-
row or other mark on its side wall to indicate the direction of rotation. Install it in a manner the direction of rotation is correct when the vehicleis driven forward.
WARNING

All four tires must be the same in terms of
manufacturer, brand (tread pattern), construc-
tion, degree of wear, speed symbol, load indexand size. Mixing tires of different types, sizesor degrees of wear can result in damage to ve-
hicle’ s power train. Use of different types or
sized of tires can also dangerously reduce
controllability and braking performance andcan 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 con-
trollability, resulting in an accident.

Wheel replacement
When replacing wheels due, for example, to dam-
age, make sure the replacement wheels match the
specifications of the wheels that are fitted as stan-
dard equipment. Replacement wheels are available
from SUBARU dealers.
WARNING
Use only those wheels that are specified for your vehicle. Wheels not meeting specifica-tions could interfere with brake caliper opera-tion and may cause the tires to rub against the wheel well housing during turns. The resulting loss of vehicle control could lead to an acci-dent.
Wheel covers
Removing the wheel cover
HGA012BA
Insert the wheel cover remover into the notch pro-
vided, and pry the wheel cover off.

Consumer information and Reporting safety defects

For U.S.A.
The following information has been compiled ac-
cording to Code of Federal Regulations “Title 49,
Part 575 ”.
Uniform tire quality grading standards
This information indicates the relative performance
of passenger car tires in the area of treadwear, trac-
tion, and temperature resistance. This is to aid the
consumer in making an informed choice in the pur-
chase of tires.
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and maxi-mum section width. For example:
Treadwear 200 Traction AA Temperature A
The quality grades apply to new pneumatic tires for
use on passenger cars. However, they do not apply
to deep tread, winter type snow tires, space-saver
or temporary use spare tires, tires with nominal rimdiameters of 12 inches or less, or to some limited
production tires.
All passenger car tires must confirm to Federal
Safety Requirements in addition to these grades.
Treadwear
The treadwear grade is a comparative rating based
on the wear rate of the tire when tested under con-
trolled conditions on a specified government testcourse.
For example, a tire graded 150 would wear one and
one-half (1-1/2) times as well on the government
course as a tire graded 100. The relative perfor-
mance of tires depends upon the actual conditions
of their use, however, and may depart significantly
from the norm due to variations in driving habits,
service practices and differences in road character-istics and climate. Traction AA, A, B, C
The traction grades, from highest to lowest, are AA,
A, B and C. Those grades represent the tire ’s ability
to stop on wet pavement as measured under con-
trolled conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C may
have poor traction performance.

Consumer information and Reporting safety defects
13-3

WARNING
The traction grade assigned to this tire is based on straight-ahead braking tractiontests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac- teristics.
Temperature A, B, C
The temperature grades are A (the highest), B, and
C, representing the tire ’s resistance to the genera-
tion of heat and its ability to dissipate heat when
tested under controlled conditions on a specified in-
door laboratory test wheel. Sustained high tempera-
ture can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C corresponds
to a level of performance which all passenger car
tires must meet under the Federal Motor Vehicle
Safety Standards No. 109. Grades B and A repre-
sent higher levels of performance on the laboratory
test wheel than the minimum required by law.
WARNING
The temperature grade for this tire is estab- lished for a tire that is properly inflated andnot overloaded. Excessive speed, underinfla-tion, or excessive loading, either separately or in combination, can cause heat buildup and
possible tire failure.
