Tire Pressure forHigh-Speed Operation
{Warning
Driving at high speeds, 160 km/h
(100mph) or higher, puts an
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
Youcould 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.
Vehicleswith P245/45R19 98V 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 260 kPa (38 psi).
Vehicleswith P245/40R20 95V 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 270 kPa (39 psi).
Professional vehicles with 235/
55R18 104H 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
40kPa (6 psi) above the
recommended cold tire pressure
shown on the Tireand Loading
Information label for the 235/
55R18 104H size tires.
Return the tires to the
recommended cold tire inflation
pressure when high-speed driving
has ended. See VehicleLoad Limits
on page 9-10 and Tire Pressure on
page 10-45.
Tire Pressure Monitor
System
The TirePressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
