Tires
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.
