Tires
When you return to normal speed
driving, be sure to readjust the tire
pressure for normal driving. You
should wait until the tires are cold
before adjusting the tire pressure.
For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver's doorjamb.
For additional technical information,
see page 340 .
Check the pressure in the tires when
the tires are cold. This means the
vehicle has been parked for at least
three hours. If you have to drive the
vehicle before checking tire pressure,
the tires can still be considered
''cold'' if you drive less than 1 mile
(1.6 km). Add or release air, if
needed, to match the recommended
cold tire pressure.
304
If you check air pressure 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 use your own tire
pressure gauge 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.
Tire Inspection
Every time you check inflation, you
should also examine the tires for
damage, foreign objects, and wear.
You should look for:
Bumps or bulges in the tread or
side of the tire. Replace the tire if
you find either of these conditions.
Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see fabric or cord.
Excessive tread wear.
