225/50/R16's are the stock tire size for OEM 16"x7" rims. They'll fit 16"x8" easily, too, but you'd be better off going a tad wider with 245/50/R16's, instead, as the 225's might look a tad skinny on 8"-wide rims. The 245's will give you a bigger contact patch (depending on tire brand/type), and there's a lot more styles and makes to choose from in that size than the 225's.
FWIW, the Fuzion ZRi's that I had on my '87 Fireturd Formula (245/50/R16) were EXCELLENT in dry or wet ... up until an old man pulled a U-turn in front of me and destroyed the whole car (including one of the tires that I had less than 2k miles on).
Bah, nonsense. You can still use those tires you will be fine. Those VW guys run like 195 on 9 inch wide wheels (for that really stretched look) although this is an extreme and actually dangerous they do get away with it.
