I think the 75's and ZT's would suite white wall tyres as of the classic look our cars have, certain colours of the 75 will obviously suite better and I for one wouldn't mind trying a set to see how they would look......
I've seen three options to try.......
Option 1, The original American White Wall Tyre from,

Option 2, White Wall Tyre Rims, these rims fit between the original tyre and the wheel around the rim. They give the effect of a white wall tyre,

Option 3, White Tyre Wall Piant, bit of a mess I can imagine,

What does everybody think? would anyone else consider the white wall tyre and please feel free in trying it first so I can see what it looks like.
(Could always do a PhotoShop)....
