178 If and when
Tyre life
Tyre life depends to a considerable extent on the following
factors:

The inflation pressures are to be found inside the fuel lid.
The inflation pressure is very important particularly at high speeds.
Therefore, the pressures should be checked at least once a
month and before every long journey.
At this opportunity do not forget the spare wheel:
• The spare wheel with normal tyre should always be inflated to
the highest pressure required on the vehicle.

• Always check the pressures when the tyres are cold. When warm,
the pressure is higher but do not reduce. If the load changes a
great deal the pressure must be altered to suit.
On vehicles with wheel hub caps, valve extensions are fitted. It is
not necessary to remove the valve extension piece in order to test
and correct the inflation pressure.

A pressure which is too low increases the fuel consumption and this
burdens the environment unnecessarily.

Fast cornering, hard acceleration and violent braking also increase
tyre wear.

The wheels on new vehicles are balanced. However when the
vehicle is running various influences can cause the wheels to
become unbalanced and this causes steering vibration.
