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 air pressures are
on a label on the driver's doorjamb.
For additional technical information,
see page

.
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 pressures,
the tires can still be considered
''cold'' if you drive less than 1 mile
(1.6 km).

Maintenance
If you check the pressures when the
tires are hot (the vehicle has been
driven several miles), you will see
readings 4 to 6 psi (30 to 40 kPa, 0.3
to 0.4 kgf/cm ) higher than the cold
readings.
Add or release air, if needed, to
match the recommended cold tire
pressures on page
221
.
Tubeless tires have some ability to
self-seal if they are punctured. You
should look closely for punctures if a
tire starts losing pressure.
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.
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 or 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.
