You are not allowed to change the axle track more than ±15mm. Therefor is it only possible to change the offset with ±7,5mm. That's why I need rims with 92,5-107,5mm offset.
The original rim has following measurements:
Width 12 inch
Diameter 26,5 inch
Offset 100 mm
Pitch circle 335 mm
Stud hole 25,4 mm
Center hole 281 mm
