15x3.5 on the street?!?

I found a guy that is selling a set of Centerline Auto Drags. They are the correct offset for my Dart and appear to be in pretty good shape. Here are a couple of pictures he sent.





I really like the big and little look, and the Centerlines will fit perfectly with the theme of my car. My only hesitation about buying them is the width of the front wheels. I wasn't planning on running a wide tire anyway, but what tire can I run that will fit on a 3.5 wheel and still be safe on the street? I know guys run VW tires, 165/15's I think, but am having a hard time finding that size on the web.

What does everyone think? Thanks!
