Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get the pressure measurement.
If the cold tire inflation pressure
matches the recommen ded
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
inflation pressure in high, press
on the metal stem in the center
of the tire valve to release air.
Re-check the tire pressure with
the tire gauge.
Return the valve caps on the
valve stems to keep out dirt and
moisture and prevent leaks.
Tire Pressure for
High-Speed Operation
{
Warning
Driving at high speeds, 160km/h
(100 mph) or higher, puts an
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
You could have a crash and you
or others could be killed. Some
high-speed rated tires require
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.
Vehicles with P245/45R17 95V,
P245/40R18 93V, or 255/
35R19 96V size tires require
inflation pressure adjustment when
driving the vehicle at speeds of
160 km/h (100 mph) or higher. Set
the cold inflation pressure to
280 kPa (41 psi).
Vehicles with 245/40R18 93Y and
275/35R18 95Y size tires require
inflation pressure adjustment when
driving the vehicle at speeds of
160 km/h (100 mph) or higher. Set
the cold inflation pressure to
300 kPa (44 psi).
Return the tires to the
recommended cold tire inflation
pressure when high-speed driving
has ended. See Vehicle Load Limits
on page 9-11 and Tire Pressure on
page 10-50.
