depth and the state of the tyres.
NOTICE
Driving with incorrect tyre pressure
The tyres wear unusually fast.

The correct tyre pressure can be
found in the tyre type table
(see from page

your trailer.
Please contact the tyre manufacturer
if your tyre type is not listed.

Recommendation:
All tyres should be replaced after 6
years of use.
