Acura 2009 TSX - Manual (Page 451)

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:
For additional information about
your tires, see page
.
For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver’s doorjamb.
We strongly recommend that you do
not drive faster than the posted
speed limits and conditions allow. If
you ever drive in a sanctioned
competitive event at sustained high
speeds (over 118 mph or 190 km/h),
be sure to adjust the cold tire
pressures as shown below. If you do
not, excessive heat can build up and
cause sudden tire failure.
