What will my OZ alloys fit ?!

[devout gooner]

I know it sounds a bit strange but I bought some OZ super tourismo wheels ,with tyres on -for the tyres! Now I have the alloys to sell on (mint cond.) I don`t know what they fit .I think they used to be on a Seat Alhambra thing but when the guy bought the diesel version they didn`t fit ,could that be right ? Can I use the serial number on any website to find the fitments?

Check on the back of the wheel, they often have the offset printed on there (should be "ET25" or something similar). The PCD you can measure yourself, just measure the diameter of an imaginary circle that passes through the centre of each bolt hole. It's probably 100mm but there are a number of standard sizes. With the wheel diameter, width, offset, PCD and number of bolt holes people can tell if they will fit their car or not.

Be careful measuring PCD, though - there are some that are quite close together (you can get both 98.4mm and 100mm, for example), so you need to measure quite accurately.
