If you overfill the tire, release air
by pushing on the metal stem
in the center of the tire valve.
Recheck the tire pressure with
the tire gauge.
Be sure to put the valve caps
back on the valve stems. They
help prevent leaks by keeping
out dirt and moisture.
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.
If your vehicle has P235/50R18 size
tires, they will require inflation
pressure adjustment when
driving your vehicle at speeds of
100 mph (160 km/h) or higher.
(Continued)
Set the cold inflation pressure to the
maximum inflation pressure shown
on the tire sidewall, or 35 psi
(241 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
and
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 35 psi (241 kPa).
