Typical Ebay seller, hence why I go armed with my PCD tool if we go and look at any second hand wheels !!!
But if its a 2007 passat OEM set of wheels then its definately 5x112, if not well thats anyones guess !!
If its 5x100 then centre of one wheel hole to the next is approx 60mm
5x112 is approx 68mm
5x110 would be a couple of mm less than the 5x112 at about 65/66mm (all measured with my trust £1 B&Q tape measure here at work lol)
