If you check air pressures when the
tires are hot (driven for several
miles/kilometers), you will see
readings 4 to 6 psi (30 to 40 kPa, 0.3
to 0.4 kgf/cm ) higher than the cold
readings. This is normal. Do not let
air out to match the recommended
cold air 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.
While tubeless tires have some
ability to self-seal if they are
punctured, you should look closely
for punctures if a tire starts losing
pressure.
The following chart shows the
recommended cold tire pressures for
most normal driving conditions.
The compact spare tire pressure is:
Check the air pressures when the
tires are cold. This means the
vehicle has been parked for at least 3
hours, or driven less than 1 mile (1.6
km). Add or release air, if needed, to
match the recommended cold tire
pressures.
Use a gauge to measure the air
pressure in each tire at least once a
month. Even tires that are in good
condition may lose 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf/cm ) per
month. Remember to check the
spare tire at the same time.
Even though your vehicle is
equipped with TPMS, 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.
For convenience the recommended
tire sizes and cold air pressures are
on a label on the driver’s doorjamb.
