Another tire fitment question…

‘66 Dart 170 2-door post.
Replacing my 13” wheels with a set of Wheel Vintique 15x6 (3.75” backspacing) steelies.
She’s not really going to be a hot-rod, rather a stock-appearing MPG queen with a Super-Six and A833OD.
I’m thinking about 205 75 R15 all the way around for a relatively stock-ish look and to achieve the goals I have for the build.
Anyone else run these?
Will there be any fitment issues?
TIA
