4. Wheels and tires
20
Tire manufacturers' recommendation
• Change tires after six years, regardless of prole depth.
• Avoid striking curbs, potholes or other obstacles.
Age of tires
Tires should not be more than 6 years old, because on the one hand
your permission to drive the caravan at 100 km/h will elapse after
this period and, on the other, the material wears out due to age and
if the tires stand too long in one spot. The 4-digit DOT number on
the side of the tire (if necessary, check the inside) shows the date
of manufacture. The rst 2 digits refer to the week, the last 2 to the
year it was manufactured.
Example:
DOT 0420 refers to week 4 in manufacturing year 2020.
4.3 Prole depth and age of tires
New tires are needed (at the latest) when the prole depth
measures 1.6 mm.
Tires age even when used rarely or not at all.
4.4 Rims Only use rims that are covered by the vehicle licence. Should you
wish to use other rims, please note the following:
Rules for the use of other rims:
- Size,
- mechanisms,
- compression depth and
- the load/bearing capacity must be sucient for the permissible
total mass.
- The chuck cone of the fastening screw must correspond to the
rim mechanisms.
Modications can only be made with the manu-
facturer's permission.
Rules for wheel screws
- wheel bolts must rst be checked after a distance of 50 km and
then checked during regular maintenance.
