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
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 P235/65R18,
P235/55R20, or 235/55R20 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 the maximum inflation
pressure shown on the tire sidewall,
or 260 kPa (38 psi), whichever
is lower. Return the tires to the
recommended cold tire inflation
pressure when high-speed driving
has ended. See Vehicle Load Limits
on page 9‑12 and Tire Pressure on
page 10‑63.
The maximum load and inflation
pressure is molded on the tire
sidewall, in small letters, near
the rim flange. It will read
something like this: Maximum load
690 kg (1521 lbs) 300 kPa (44 psi)
Max. Press.
Tire Pressure Monitor
System
The Tire Pressure 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
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
