High-Speed Operation - Chevrolet 2007 Corvette Owner's Manual

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.
388
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 309.
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.
