Acura 2004 RL - Owner's Manual - Manual (Page 283)

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 ) per month.
Remember to check the spare tire at
the same time you check all the
other tires.
The following chart shows the
recommended cold tire pressures for
most normal driving conditions and
speeds. Tire pressures for high
speed driving are the same as for
normal driving.
The compact spare tire pressure is:
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.
Check the pressure in the tires when
they are cold. This means the vehicle
has been parked for at least three
hours. If you have to drive the
vehicle before checking the tire
pressure, the tires can still be
considered ‘‘cold’’ if you drive less
than 1 mile (1.6 km).
If you check the pressure when the
tires are hot [the vehicle has been
driven 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 reading. This is normal.
Do not let air out to match the
specified cold pressure. The tire will
be underinflated.
Add or release air, if needed, to
match the recommended cold tire
pressures on this page. For convenience, the recommended
tire sizes and cold air pressures are
on a label on the driver’s doorjamb.
