Tire placard
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.
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
2
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).
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.
Correctly inflated tires (tread
.
worn evenly)
) when the
Roadholding is good, and steering
is responsive. Rolling resistance is
low, so fuel consumption is also
lower.
