Wheel offset?

Jesper Slattengren
So when I modify the tire/wheel, there is a field for wheel_offset. Which makes perfect sense. The wheel center is a design position on the intersection between the spin axis and the mating surface where the wheel is bolted on. On this design, different wheels can be used with different offsets. That will among other things change the scrub radius.
The problems are
  1. This parameter is not used by anything. Changing it does not move the tire in or out.
  2. Using the suspension testrig, there is nowhere to set this parameter. As this is using a testrig tire that does not expose this parameter. I can change it by manually search for this variable and change it. But it looks like an oversight. And it does not change the scrub radius or anything else in the simulation
 
OK, it is easy to fix for the full vehicle tire template, but it seems wrong to me.
 
Anyone else looked into this? @Martin Kieltsch​ you must have fixed this?

    in FTire, we have wheel offset (=ET=Einpresstiefe, as Martin said) in the tire/rim data file. If this value is set, Adams is expected to give the location/motion of the *geometrical* center point of the rim as input to FTire; FTire takes into account the ET.
    If you prefer to handle wheel offset directly in your Adams model, this is no problem. In this case, you must set ET=0 in the tir-file (which obviously is the default).
    Very small disadvantage of the first method (ET set in the tir-file): you will not see the wheel offset in the Adams online animation. But you *will* see it in FTire's own animation window, and in the ogl-file-based offline animation in Adams/ PPT.
