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 P255/50R20 104V 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 38 psi (262 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 350 .
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.
