17" alloys???

Hi, I've just signed up to this forum after finding out about it on seatcupra.net which i'm a member of and i'm looking for info on 17" skoda zenith alloys, basically i drive a seat ibiza fr tdi and wondered if these alloys would fit straight on as i can't find any info about pcd or offset about them anywhere and any help would be really appreciated, apologises if i've posted this request in the wrong part of the forum also.

Cheers Dave.
