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.
5-66
If you will be driving your vehicle at speeds of 175 mph
(282 km/h) or higher, where it is legal, set the cold
inflation pressure to the maximum inflation pressure
shown on the tire sidewall, or 38 psi (265 kPa),
whichever is lower. See the example following.
When you end this high-speed driving, return the tires
to the cold inflation pressure shown on the Tire and
Loading Information label. See Loading Your Vehicle
on page 4-33.
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 38 psi (265 kPa).
Racing or other competitive driving may affect the
warranty coverage of your vehicle. See your warranty
booklet for more information.
