Tires
Inflation
Keeping the tires properly inflated
provides the best combination of
handling, tread life and riding
comfort. Underinflated tires wear
unevenly, adversely affect handling
and fuel economy, and are more
likely to fail from being overheated.
Over-inflated tires can make your car
ride more harshly, are more prone to
damage from road hazards, and wear
unevenly.
We recommend that you visually
check your tires every day. If you
think a tire might be low, check it
immediately with a tire gauge.
Use a gauge to measure the air
pressure at least once a month. Even
tires that are in good condition may
lose one to two psi (10 to 20 kPa, 0.1
to 0.2 kgf/cm
2
) per month.
Remember to check the spare tire at
the same time you check all the
other tires.
Check the pressure in the tires when
they are cold. This means the car
has been parked for at least three
hours. If you have to drive the car
before checking the tire pressure,
the tires can still be considered
"cold" if you drive less than 1 mile
(1.6km).
If you check the pressure when the
tires are hot (the car has been driven
several miles), you will see readings
4 to 6 psi (30 to 40 kPa, 0.3 to 0.4
kgf/cm
2
) higher than the cold
reading. This is normal. Do not let
air out to match the specified cold
pressure. The tire will be
underinflated.
You should get your own tire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier for you to tell if a
pressure loss is due to a tire problem
and not due to a variation between
gauges.
