Tire Pressures And Wear - Subaru Ascent 2023 Manual

498
Tires and wheels
you park the vehicle.
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 da-
maged. Drive slowly to the
nearest authorized SUBARU
dealer and have the vehicle
inspected.
& Tire pressures and wear
Maintaining 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 door 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 out-
side temperature. It is best to check
tire pressure outdoors before driv-
ing 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
when the tire becomes warm.
The tires are considered cold
.
when the vehicle has been
parked for at least three hours
or has been driven less than 1
mile (1.6 km).
WARNING
Do not let air out of warm tires
to adjust pressure. Doing so
will result in low tire pressure.
Incorrect tire pressures detract from
controllability and ride comfort, and
they cause the tires to wear abnor-
mally.
