Tyres TYRE CARE
Do not drive the vehicle if a tyre is
damaged, excessively worn, or
incorrectly inflated.
Avoid contaminating the tyres with
vehicle fluids as they may cause
damage to the tyre.
Avoid spinning the wheels. The forces
released can damage the structure of
the tyre and cause it to fail.
If wheel spin is unavoidable due to a
loss of traction (in deep snow, for
example), do not exceed 50 km/h (30
mph).
Do not exceed the maximum pressure
stated on the sidewall of the tyre.
TYRE PRESSURES
Never drive your vehicle if the tyre
pressures are incorrect.
Pressure checks should only be
carried out when the tyres are cold,
and the vehicle has been stationary
for more than three hours. A hot tyre at
or below recommended cold inflation
pressure is dangerously
under-inflated.
If the vehicle has been parked in
strong sunlight, or used in high
ambient temperatures, do not reduce
the tyre pressures. Move the vehicle
into the shade and allow the tyres to
cool before re-checking the
pressures.
CHECKING THE TYRE PRESSURES
The recommended tyre pressures are listed on
a label located in the driver’s door opening.
Check the tyres, including the spare, for
condition and pressure on a weekly basis and
before long journeys.
If tyre pressures are checked while the vehicle
is inside a protected covered area (e.g. a
garage) and subsequently driven in lower
outdoor temperatures, tyre under-inflation
could occur.
A slight pressure loss occurs naturally with
time. If this exceeds 0.14 bar (2 psi, 14 kPa,)
per week, have the cause investigated and
rectified by qualified assistance.
If it is necessary to check tyre pressures when
the tyres are warm, you should expect the
pressures to have increased by up to 0.3 - 0.4
bar (4 - 6 psi, 30 - 40 kpa). Do not reduce the
tyre pressures to the cold inflation pressure
under these circumstances. Allow the tyres to
cool fully before adjusting the pressures.
