10.8 Rims
The implement's rims have a bearing load
≥ than the tyres used.
The rim offset is +ET 70 or +107 (at a rim
strength of 13 mm).
The rims can be used on both sides.
The rims have the following specifications:

+107/-120)
10.9 Explanation of the terms offset and track change
Offset
positive offset
negative offset
the dimension from the centre of the wheel rim to the inner
contact surface of the wheel on the hub of the axle. The off-
set can be stated as positive (+) or negative (-). A positive
offset results in a narrower track width and a negative offset
in a wider track width.
Track change
The left wheel is mounted in the same running direction on the right side of the
implement and the right wheel in the same running direction on the left side of the
implement.
