Tyre Pressure For High-Speed; Operation - Chevrolet Corvette Owner's Manual

pressure on the Tyre and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
inflation pressure in high, press
on the metal stem in the centre
of the tyre valve to release air.
Re-check the tyre pressure with
the tyre gauge.
Put the valve caps back on the
valve stems to keep out dirt and
moisture and prevent leaks. Use
only valve caps designed for the
vehicle by GM. TPMS sensors
could be damaged and would
not be covered by the vehicle
warranty.
Tyre Pressure for
High-Speed Operation
Warning
Driving at high speeds, 160 km/h
(100 mph) or higher, puts
additional strain on tyres.
Sustained high-speed driving
causes excessive heat build-up
and can cause sudden tyre
failure. This could cause a crash,
and you or others could be killed.
Some high-speed rated tyres
require inflation pressure
adjustment for high-speed
operation. When speed limits and
road conditions allow the vehicle
to be driven at high speeds, make
sure the tyres are rated for
high-speed operation, are in
excellent condition, and are set to
the correct cold tyre inflation
pressure for the vehicle load.
The tyres require inflation pressure
adjustment when driving the vehicle
at speeds of 160 km/h (100 mph) or
Vehicle Care
higher, where it is legal. Set the cold
inflation pressure to the maximum
inflation pressure shown on the tyre
sidewall, or 265 kPa (38 psi),
whichever is lower. See the
example following. Return the tyres
to the recommended cold tyre
inflation pressure when high-speed
driving has ended. See Vehicle
Load Limits 0 168.
Example:
The maximum load and inflation
pressure moulded on the tyre
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, set the inflation
pressure for high-speed driving to
265 kPa (38 psi).
Racing or other competitive driving
may affect the warranty coverage of
the vehicle. See the warranty
booklet for more information.
