    How does the offset affect the position of the rim in relation to the hub?

    The lower the offset (et 20) the more the wheel sticks out, the higher the offset (et 48) the closer it sits inside the arch. So an et of 20 means the wheels stick out more, and et 48 means the opposite.

    So is the off set measured from the outer rim of the wheel?

    Its the distance from the centreline of the rim, to the hub mounting flange.

    Most cars have positive offset, which means the hub flange is closer to the front face of the wheel.

    Audis standard offset on the B5 is 45mm or ET45, which means the flange is 45mm closer to the front of the rim than the wheel centreline.
