J 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 tire
to 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 vehicle
is driven forward.
WARNING
D All four tires must be the same in terms of
manufacturer, brand (tread pattern), construc-
tion, degree of wear, speed symbol, load index
and size. Mixing tires of different types, sizes
or 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 and
can lead to an accident.
D 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.
