MAINTAINING YOUR McLAREN
WHEELS AND TYRES
Driving Precautions
When parking your McLaren, ensure that the
tyres do not contact the kerb or other
obstacles. If it is necessary to drive over kerbs,
speed humps or potholes, drive slowly and at
a shallow angle or the tyres could be
damaged.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the tyres or wheels are damaged. If you
experience anything unusual, reduce your
speed and stop the vehicle as soon as safety
permits to check the tyres and wheels for
damage. If you find no signs of damage, have
the tyres and wheels inspected at your
McLaren Retailer.
Tyre Pressures
WARNING: Tyre pressure that is too high
or too low has a negative effect on the
vehicle's active safety, this could lead to
an accident. Frequently check the
pressure of all tyres, particularly prior to
long trips, and correct the pressure as
necessary.
5.46
WARNING: If the pressure in a tyre drops
repeatedly, inspect the tyre for foreign
objects or signs of punctures, check the
valve for air leaks.
For the tyre pressures for various operating
conditions, see Tyre Pressures, page 7.8. They
are also printed on a label attached to the
driver's side sill panel.
If the vehicle is to be driven at high speeds,
the tyre pressure must be checked, and if
necessary adjusted.
NOTE: Tyre pressures given for low loads
are minimum values which offer
optimum ride comfort.
Increased pressures for higher loads will
not adversely affect the vehicle, but ride
comfort will be impaired.
Check the pressures when the tyres are cold.
If it is necessary to check the tyres when they
are warm, pressures will be higher. Do not let
air out of warm tyres to match the
recommended cold tyre pressures.
WARNING: Driving with a tyre pressure
that is too high or too low can create a
risk of tyre failure with resultant
accidents, causing injury or death.
Other consequences of driving with incorrect
tyre pressures are:
the life of the tyres is shortened

damage to tyres can be increased

have a negative effect on handling

characteristics (e.g. by causing
aquaplaning)
ENVIRONMENTAL: Check tyre pressures
at least every 14 days.
