Profile depth (around middle of tread)
WARNING
Worn tyre profile / incorrect tyre pressure!
The tyres could burst while driving – accident risk! The
braking distance increases - risk of snaking!
Regularly check the tyres.
Check the tyre pressure, profile depth and condition of
the tyres - see maintenance table.
Even on trailers which are not used very often, the
tyres are subject to the influence of the weather,
such as sunshine, cold, etc. which will cause the
tyres to age faster.
Regularly carry out a thorough visual inspection of the
tyres.
Look out for possible cracks and foreign bodies.
Replace the tyres after approx. 6 years use- over time,
rubber becomes porous and brittle.
Check the profile depth of the tyres around the middle of
the tread (Fig. 14 /1).
In Germany, a minimum of 1.6 mm is required.

Tyre pressure - data
1
in bar (kPa)
2
in psi (pounds per square inch)
NOTICE
Driving with incorrect tyre pressure
The tyres will wear disproportionately.
Before setting off and at the latest 14 days later, check
the tyre pressure on cold tyres.
Conversion bar / psi / kPa:
1 psi = 0.0689 bar
1 bar = 14.504 psi or 100 kPa
1 kPa = 0.01 bar
Check the tyre pressure on all wheels on a regular basis
and before long journeys.
You will find the correct tyre pressure in the information
on the tyre (Fig. 15 ).
If necessary, convert the information in psi to bar first.
For orientation purposes, you will find the tyre pressure
in the following table.
