How to Check
Use a good quality pocket-type
gauge to check tire pressure.
You cannot tell if your tires
are properly inflated simply by
looking at them. Radial tires may
look properly inflated even when
they are under inflated. Check
the tire's inflation pressure when
the tires are cold. Cold means
your vehicle has been sitting for
at least three hours or driven no
more than 1 mile (1.6 km).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until you reach the
recommended amount.
If you overfill the tire, release
air by pushing on the metal stem
in the center of the tire valve.
Re check the tire pressure with
the tire gauge.
Be sure to put the valve caps
back on the valve stems.
They help prevent leaks by
keeping out dirt and moisture.
Tire Pressure for
High-Speed Operation
WARNING
Driving at high speeds, 160 km/h
(100 mph) or higher, puts an
additional strain on tires.
Sustained high-speed driving
causes excessive heat build up
and can cause sudden tire failure.
You could have a crash and you
or others could be killed. Some
high-speed rated tires require
WARNING (Continued)
inflation pressure adjustment for
high speed operation. When
speed limits and road conditions
are such that a vehicle can be
driven at high speeds, make sure
the tires are rated for high speed
operation, in excellent condition,
and set to the correct cold tire
inflation pressure for the
vehicle load.
If you will be driving your vehicle at
speeds of 175 mph (282 km/h) or
higher, where it is legal, set the cold
inflation pressure to the maximum
inflation pressure shown on the
tire sidewall, or 38 psi (265 kPa),
whichever is lower. See the
example following. When you end
this high-speed driving, return the
tires to the cold inflation pressure
shown on the Tire and Loading
Information label. See Vehicle Load
Limits on page 9 14.
