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.
DANGER
Damaged tyres or wheels may be the cause of a serious accident.
Checking tyre pressure and steel rims:
•
every 3 months of use,
•
if needed.
