Honda 1997 Civic Sedan Online Reference Owner's Manual page 152

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 (0.3 to 0.4 kgf/cm
kPa) 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.
Recommended Tire Pressures for
Normal Driving
The following chart shows the
2
, 30 to 40 recommended cold tire pressures for
most normal driving conditions and
speeds. Tire pressures for high
speed driving are shown on page
205.
The compact spare tire pressure is:
420 kPa (4.2 kgf/cm
These pressures are also given on
the tire information label on the
driver's doorjamb.
Tubeless tires have some ability to
self-seal if they are punctured.
However, because leakage is often
very slow, you should look closely
for punctures if a tire starts losing
pressure.
