High-Speed Operation
{
CAUTION:
Driving at high speeds, 100 mph (160 km/h)
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.
If your vehicle has P255/55R18 104H size tires
installed on the rear axle, they will require
inflation pressure adjustment when driving your
vehicle at speeds above 99 mph (160 km/h).
Set the cold inflation pressure, for the rear tires
only, to the maximum inflation pressure shown on
the tire sidewall, or 36 psi (248 kPa), whichever
is lower. See the example following. When you end
this high-speed driving, return the tires to the
cold tire inflation pressure shown on the Tire and
Loading Information label. See
Loading Your
Vehicle on page 296 .
Example:
You will find the maximum load and inflation
pressure molded on the tire’s 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.
For this example, you would set the inflation
pressure for high-speed driving at
36 psi (248 kPa).
The inflation pressure for the front tires should be
set to the cold tire inflation pressure shown on
the Tire and Loading Information label.
Racing or other competitive driving may affect the
warranty coverage of your vehicle. See your
warranty booklet for more information.
