Hi all, looking to get some new alloys for my Astra MK5. I have seen these 18" alloys on ebay:


Firstly if someone could let me know if they have had any experience with these or know someone who has and secondly, what tyre size would fit onto these? Just want to get some idea of total cost before forking out.

Also, if I do get these, any ideas on how much I could potentially get for a set of 17" Astra Pentas in good nick?
