CHECKING AIR PRESSURE IN TYRES, EVALUATING TECHNICAL
CONDITION OF TYRES AND STEEL WHEELS
Tyre pressure should be checked each time after changing spare wheel and not less than
every month. In the event of intensive use, air pressure in tyres should be checked more
frequently. During this time, the trailer must be unloaded. Checking should be done before
travelling when tyres are not heated, or after an extended period of parking.
TIP
Tyre pressure values are specified in information decal, placed on wheel or on upper
frame above trailer wheel.
DANGER
Damaged tyres or wheels may be the cause of a serious accident.
While checking pressure pay attention to technical condition of wheels and tyres. Look
carefully at tyre sides and check the condition of tread.
In case of mechanical damage consult the nearest tyre service and check whether the tyre
defect requires tyre replacement.
Wheels should be inspected with regard to distortion, breaking of material, breaking of welds,
corrosion, especially in the area of welds and contact with tyre.
Proper technical condition and appropriate maintenance of wheels significantly extends the
life of these components and ensures appropriate level of safety to trailer users.
