Explanation of offset
The inside of the rim left, the outside of the rim right, and the dotted line indicates the axle.
- ET30 = If a narrow tire with a positive offset is selected, the tire will not widen the overall width of the machine, where applicable. This is suitable if the machine need to pass through narrow routes.
- ET0 = A compromise between a narrow machine width and good stability.
- ET-30 = If a tire with a negative offset is selected, the tire will not widen the overall width of the machine, where applicable. A wide tire and contact area increases stability.
