Inflation
Keeping the tires properly inflated
provides the best combination of
handling, tread life, and riding
comfort. Underinflated tires wear
unevenly, adversely affect handling
and fuel economy, and are more
likely to fail from being overheated.
Overinflated tires can make your
vehicle ride more harshly, are
more prone to damage from road
hazards, and wear unevenly.
We recommend that you visually
check your tires every day. If you
think a tire might be low, check it
immediately with a tire gauge.
Use a gauge to measure the air
pressure at least once a month.
Even tires that are in good
condition may lose one to two psi
per month. Remember to check
the spare tire at the same time you
check all the other tires.
Check the pressure in the tires
when they are cold. This means
the vehicle has been parked for at
least three hours. If you have to
drive the vehicle before checking
the tire pressure, the tires can still
be considered "cold" if you drive
less than 1 mile (1.6 km).
If you check the pressure when
the tires are hot (the vehicle has
been driven several miles), you
will see readings 4 to 6 psi (28 to
41 kPa, 0.3 to 0.4 kg/cm
2
) 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 at all
times. That makes it easier for
you to tell if a pressure loss is
caused by a tire problem and not a
variation between gauges.
Recommended Tire Pressures for
Normal Driving
The following chart shows the
recommended cold tire pressures
for most normal driving
conditions and speeds.
