5.9 MEASUREMENT OF AIR PRESSURE, TIRES AND RIMS CHECK
During pressure measurement the trailer
must be unloaded. The check should be
carried out before driving off, when the tires
are not warmed up, or after a longer stand-
still of the trailer.
SCOPE OF ACTIONS
• Connect a pressure gauge to the
valve.
• Check air pressure.
• If necessary, pump the wheel to the
required pressure.
The required air pressure is de-
scribed on a sticker (1) on the
rim.
• Check tread depth.
• Check the sidewall of the tire.
• Inspect the tire for defects, cuts, de-
formations, protrusions that indicate
mechanical damage to the tire.
• Check that the tire is correctly po-
sitioned on the rim.
• Check the tire age.
When checking pressure, pay attention to
the technical condition of rims and tires. In
the event of mechanical damage, consult
your nearest tire service center and make
sure that the tire defect is eligible for
replacement.
The rims should be checked for
deformation, material cracks, weld cracks,
corrosion, especially around the welds
and in the place of contact with the tire
I.3.4.622.09.1.EN
ADVICE
In the event of intensive use of the trailer, we recom-
mend more frequent pressure checks.
Using the trailer in which tires are not properly infla-
ted may lead to permanent damage to the tire as a
result of delamination of the material.
Incorrect tire pressure is also a reason for faster tire
wear.
