Can anyone please tell me the exact dimensions of 18" wheels fitted to a 3.6 4x4. I'd like to know the rim width and offset (ET)?

 

Thanks.

They can't be no different to the Octavia vrs 18" alloys can they? I don't know the answer. But someone else might?

Well width is 225/40 and believe offset is ET45

Thanks for your replies but I'm still trying to find the OEM rim width, is it 7.5" or 8" x 18". You're right of course Nathanio about the tyre size 225/40 which could be fitted to either rim size.

Yes

The Superb uses 7.5" x 18" and ET47 (from memory) whereas the vRS is ET54 (ish) but still 7.5" wide.

Excellent. Just what I needed to know.

18" x 7.5" Thermisto wheels have an ET46, it is marked as such on the inside of the wheels,

 

The other measurments worth knowing are PCD = 5x112mm and Bore = 57.1mm
