Escort run ET from 22 to 15 a d have a deeper dish
I run ET 23 on one set of wheels and they stick out further than ET35
A lot of deep dish Escort wheels are 0 ET you can see the difference

The "ET45" figure below that though symbolises that these wheels have a positive offset of 45mm
In other words, they have an inset of 45mm.

I can explain it to you but can't understand it for you

All of that is completely obvious to me. But we were discussing the distance between the wheel mounting faces. Positive offset means the mounting faces are further apart than the wheel centrelines. You said:

Wheel offset ET for Sierra was 38 and is a minus figure

Which is just wrong in this context.
