Wheel Offsets......again!!

Want to order my new wheels but still unsure of the offset, so I have attached a diagram of how I think it is.
I currently have 6x14 wheels with an offset of 16mm and the wheels Im looking at are 6.5x15 with an offset of 20mm. Going by how I understand things (rightly or not) the new 15" wheels will protrude an extra 2-3mm further than the old wheels. I know 2-3mm is nothing to worry about, but just want to know if I've understood this correctly.

Cheers

ps sorry for the crappy scan

Looks reet to me...

(from one Preston lad to another...)

you understand it correctly that looks about right to me

They are going to protude much further inward, is your lock ok, clearance on trailing arms etc?

Inwards, or that's how i see it any road....but then it's late

Yup they'll be 10.35mm closer to whatever is behind the wheel...

Cheers

Thanks guys. I can now order with confidence.

offset is given by ET and can be both positive or negavie; make sure it is the correct one.

and yes, your picture is correct with how you understand it.
