Wheels?

Attachment 1585

You can have a 3'' wide wheel or a 9'' with an ET38, the offset will still be the same. Just the wheel will be wider, so wider outward AND inward

Hope I'm clear in my explanations

Ah ha!!!!! No idea why I was being so thick!!!

I was thinking that the offset was measured TO the centreline, rather than FROM the centreline. I was also making the assumption that wheels were made wider by just adding width to 'the inside' rather than widening inward and outward...

Silly me!
