The wheel offset (ET) defines the distance of the flange from the centre of the wheel mouth in millimetres. If the offset is zero, the flange is located exactly in the centre of the wheel, and the wheel extends exactly as far outwards as inwards. For example, a 9 inch width wheel with an offset of zero extends 11.43 cm outwards and 11.43 cm inwards. A positive offset (e.g. +25) indicates that the wheel extends further inwards (towards the centre of the vehicle) than outwards (towards the wing housing).
Starting from zero, the track would become narrower by 25 mm. A negative offset (e.g. -25) would mean that the wheel extends outwards and the track would be wider (again by 25 mm starting from zero). If we therefore had two pairs of wheels of equal width to choose from, one having an offset of plus 25 mm and the other minus 25 mm, we could make the track 5 cm wider on each side by fitting the pair with the negative offset rather than the other pair. In total the track would be 10 cm wider than with the "positive offset" wheels.
