Maintaining Your McLaren
Wheels and Tires
6.23
The outer tread features a larger stiffer
tread pattern that aids with cornering
stability. The inner tread pattern aids
stability in wet conditions. A central groove
in the tire aids straight line stability.
WARNING: Only tires recommended
by McLaren are to be fitted to the
vehicle. See
Wheel And Tire Sizes,
page 7.7 .
WARNING: The tires must be
mounted according to the labelling
on the tire wall. The benefits of
asymmetric tires will only be
available if the tires are fitted
correctly.
Inspecting Wheels And Tires
Check the tires at least every 7 days for
cuts, punctures, tears, bumps, deformation
and cracks. Check the wheels for severe
corrosion. Damaged wheels could cause a
loss of tire pressure.
Regularly check the tire tread depth and
the condition of the tread across the whole
width of the tire. Turn the front wheels to
full lock in order to inspect the inner tread.
When the tread is worn to 1.6 mm the wear
indicators appear on the surface of the
tread pattern. This produces a continuous
band of rubber across the width of the tire.
tires must be replaced as soon as the wear
indicator becomes visible or sooner if
legislation dictates replacement at a
greater tread depth.
NOTE: It is recommended that you
always have your tires replaced by
your McLaren retailer. Each wheel
has a tire pressure sensor
connected to the tire valve. To avoid
damage to the sensor the tires must
be replaced using the correct
procedure.
WARNING: Summer and UHP tires
are designed for optimal
performance in warm, dry
conditions. Their grip decreases on
wet or icy roads. You could lose
control of the vehicle and cause an
accident due to the reduced grip of
the tires. In wet or icy conditions
reduce your speed and drive with
greater care.
NOTE: If tread wear is uneven across
the tire, or becomes excessive, the
wheel alignment should be checked.
Regularly check the pressure of all your
tires and correct the pressure if necessary.
See Tire Pressures, page 7.8.
All wheels must have a valve cap fitted to
protect the valve against dirt and moisture.
