4.12.1
Checking condition of tyre
For delivery inspection:
– Check tyre treads and side walls for damage and remove for‐
eign bodies such as, for example, nails or glass splinters.
WARNING
If damage is determined, always check to see if a new tyre
should be fitted.
For service:
– Check tyre treads and side walls for damage and remove for‐
eign bodies such as, for example, nails or glass splinters.
– Check tyres for cupping, one-sided wear, porous side walls,
cuts and punctures.
– Check tyre age. We recommend not to use any tyres older
than 6 years. Inform customer!
WARNING
The customer must be informed of any faults found.
4.12.2
Checking wear pattern
Note
The wear pattern on the front tyres will indicate, for example, if
toe and camber settings should be checked:
Causes:
♦ Feathering on tread indicates incorrect toe setting.
♦ One-sided tread wear is mainly attributed to incorrect camber.
– When wear of this nature is detected, determine cause by
checking alignment (repair measure).
4.12.3
Checking tread depth (including spare
wheel)
– Check tyre tread depth.
Minimum tread depth: 1.6 mm
Note
♦
This figure may vary according to legislation in individual coun‐
tries.
♦
The minimum tread depth is reached when the tyres have
worn down level with the 1.6 mm high tread wear indicators
positioned at intervals around the tyre.
♦
If the tread depth is approaching the minimum allowed depth,
inform the customer.
