15x3.5 on the street?!?

Brian -
I like the same type of look, but I decided on 15x6 rims with either 195 or 215 tires for the front of my '69 Dart, and 15x8 rims with 275 tires on the back.
Much safer IMO but still gets the look across.
Make sure you check out the load ratings on whatever size tire you decide to go with.
