Honda Civic Owner's Manual page 321

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.
Recommended Tire Pressures
The following charts show the
recommended cold tire pressures for
most normal driving conditions.
(DX, Canadian DX-G with automatic
transmission)

P195/65R15 89H Front/Rear:
30 psi (210 kPa ,
2.1 kgf/cm )
(Canadian DX-G with manual
transmission)
Tire Size Cold Tire Pressure
P195/65R15 89S Front/Rear:
30 psi (210 kPa ,
2.1 kgf/cm )
(EX-L, U.S. LX, LX-S, EX, Canadian
SE)
Tire Size Cold Tire Pressure
P205/55R16 89H

2.2 kgf/cm )
(Si)
Tire Size Cold Tire Pressure
P215/45R17 87V Front/Rear:
33 psi (230 kPa ,
2.3 kgf/cm )
Optional for U.S. Si
Tire Size Cold Tire Pressure
215/45ZR17 91W Front/Rear:
33 psi (230 kPa ,
2.3 kgf/cm )
The compact spare tire pressure is:

For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver's doorjamb.
