I believe its how far in or out the rim sits on the hub, thats why front wheel drive rims will fit an Omega but sit a long way into the wheel arch because it is a different offset to the rear wheel drive set up.

Great stuff, interesting reading, still none the wiser as to whether the offset 38's are OK as irmscher only show offset 30's for the omega Undecided

no, the 235/40 only relates to the tyre

235 being the width in mm? i believe the 40 is the sidewall measurement, given in a percentage figure, of the tyre width?
