pudders

I want a set of 5 spoke alloys for my work car a Ford Escort TD. The ones like found on a Escort GTI or Mondeo SI. Question is which ones am I looking for. I dont know whether they are 15 or 16 " . Are the wheels the same between the escort and mondeo. I have seen some 16" ones on ebay but are these the right ones. What tyre size do I need. Currently running the standard Ghia 6 soke 14" wheels on 185 by 65 I think. Any ideas or know of any for a good price in good nick?
