can somebody fill me in??????
 

what is this mm offset everyone keeps talking about on wheels and what does it do?can someone give me a clue,i have no idea,thanx

If someone was to draw a line down the centre of the width of a wheel, the offset would be the distance between the back face (mounting face) of the wheel and the centre line.

It is vital not to deviate too far from the offset of the wheel originally fitted to the vehicle. A wheel of radically different offset can cause serious clearance and handling problems along with accelerated tyre and bearing wear.

The offset of the wheel can normally be found at the back of the wheel. “ET” precedes the offset and is therefore also referred to as the ET numbers e.g. ET35 = Offset of Plus 35mm.

here is a pic to help
