Max wheel size for Spit

[pk@kom.auc.dk (Peter Koch)]

After I have seen the photo of Mark Bradakis' good looking
Spitfire at WWW, I have realized that my '72 MkIV need
some kind of improvement. For qiute some time now, I
have thought of buying some bigger wheels for her (as 
compared to the standard size which is 13 x 4'', I guess),
and thus by question now is: What are yours recommandations
on max wheel sizes? I think maybe tires with sizes in the
range 185 - 195 60 x 13 will do, but it's only my
initial guess.

Thanks for your time...
