Wheel Dilemma

Hi folks hope you can help. I've purchased a set of Wolfrace wheels from a local dealer for my Megane 3. I have now sold the car and looking to sell the wheels but not sure what they fit. I know they are 5x114 PCD but I'm struggling with the centre bore size as they don't seem to fit any other car I've tried. Any ideas what they would fit?
Wheels were on for less than two months, any offers welcome. They are Wolfrace GB Lugano's 225/45R17

Thanks
 
Do they have spigot rings in them?

A removable plastic ring in the centre of the wheel?
