Maintenance and service/Tires and wheels
. If you feel unusual vibration while
driving or find it difficult to steer the
vehicle in a straight line, one of the tires
and/or wheels may be damaged. Drive
slowly to the nearest authorized
SUBARU dealer and have the vehicle
inspected.
& Tire pressures and wear
S11AV04
Maintaining the correct tire pressures
helps to maximize the tires’ service lives
and is essential for good running perfor-
mance. Check and, if necessary, adjust
the pressure of each tire (including the
spare) at least once a month (for example,
during a fuel stop) 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 values shown on the
tire placard. The tire placard is located on
the door pillar on the driver’s side.

Incorrect tire pressures detract from con-
trollability and ride comfort, and they cause
the tires to wear abnormally.
. Correctly inflated tires (tread worn
evenly)
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 ve-
hicle.
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).
Roadholding is good, and steering is
responsive. Rolling resistance is low, so
fuel consumption is also lower.
WARNING
Tire placard
Do not let air out of warm tires to
adjust pressure. Doing so will result
in low tire pressure.
