Hopefully I got this now....there seems to be an issue with the import obj which changes the size.
so this is fixed now...but when importing it was 100x smaller so I changed the export scale in Nvil and now it seems spot on...going to test some more tomorrow.
tnx.

If use MoI > subd > create tool to import the obj data it will convert it to a subd nurbs surface which will change its size slightly as the subd algorithm tries to round off all the edges of the cylinder.

I set MoI to meters
I created a 0.1m x 0.1m x 0.1m cube in MoI.
Exported the cube from MoI to obj
I set NVil to meters in preferences
Merge Scene > obj
I set import scale to 1
I used the measure tool > measure between snap points
It comes into NVil perfectly to size at 0.1m
If you set NVil preferences to cm and import scale to 1 it comes in perfectly to size also.
I tested your wheels 1302.obj file
When NVil is set to meters and they are imported at 1 scale
Each wheel is 43.7721m diameter x 26.9996m high
