WHEELS AND TYRES
2 REPAIR
When the indicators appear in two or more adjacent
grooves, at three locations around the tyre, a new tyre
must be fitted.
NOTE: DO NOT attempt to interchange
tyres, e.g. from front to rear, as tyre wear
produces characteristic patterns
depending on their position. If tyre position is
changed after wear has occured, the performance
of the tyre will be adversely affected.
NOTE: Territorial vehicle regulations
governing tyre wear MUST be adhered to.
WHEELS INSPECTION
Regularly check the condition of the wheels. Replace
any wheel that is bent, cracked, dented or has
excessive runout.
VALVES INSPECTION
Check condition of inflation valve. Replace any valve
that is worn, cracked, loose, or leaking air.
TYRE PRESSURES
Maximum tyre life and performance will be
obtained only if tyres are maintained at the correct
pressures .
Tyre pressures must be checked at least once a week
and preferably daily, if the vehicle is used off road.
The tyre inflation pressure is calculated to give the
vehicle satisfactory ride and steering characteristics
without compromising tyre tread life. For
recommended tyre pressures in all conditions
See
INTRODUCTION, Information, Wheels and Tyres .
Always check tyre inflation pressures using an
accurate gauge and inflate tyres to the
recommended pressures only .
Check and adjust tyre pressures ONLY when the
tyres are cold, vehicle parked for three hours or more,
or driven for less than 3.2 km (2 miles) at speeds
below 64 km/h (40 mph). Do not reduce inflation
pressures if the tyres are hot or the vehicle has been
driven for more than 3.2 km (2 miles) at speeds over
64 km/h (40 mph), as pressures can increase by 0.41
bars (6 lb/in
2
) over cold inflation pressures.
Check ALL tyre pressures including the spare. Refit
the valve caps as they form a positive seal and keep
dust out of the valve.
