HIGH SPEED OPERATION
CAUTION
Driving at high speeds,
160 km/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 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 permit a
vehicle to be driven at high
speeds, make sure the tires are
rated for high-speed operation,
are in excellent condition, and
are set to the correct cold tire
inflation pressure for the vehicle
load.
You must adjust the tire pressure
for high-speed driving if the
vehicle is equipped with the
following high-performance tire
sizes:
• 235/50ZR18
• 255/40R19
• 285/35R19
If you will be driving at speeds of
160 km/h (100 mph) or faster,
where it is legal, set the cold infla-
tion pressure to the maximum
inflation pressure shown on the
tire sidewall or to 300 kPa (44psi),
whichever is lower. When you end
this high-speed driving, return to
the cold inflation pressure shown
on the tire information label.
See "Vehicle Loading" in Section 3
for more information.
Tire Pressure Monitor (If
equipped)
NOTICE
Modifications made to the tire
pressure monitor system by
anyone other than an autho-
rized service facility may void
authorization to use the system.
This system uses radio and sensor
technology to monitor tire
pressure.
