 ❱OFFSET
The offset is the distance from the centre-line to the back side of the wheel disc (Where  
the wheel is fitted to the hub). The offset can be positive (+) or negative (-). A positive  
offset results in a narrower track width, i.e. Brings the wheel closer to the machine body. 
A  negative offset will result in a wider track width, thus taking the wheel further away 
from  the machine body. The following drawings illustrate positive and negative offsets.
