What size of 17" tires for early a?

Well I decided to do the 17" Rallye look alike wheel on my 1966 Dart. I was wondering what size of 17's will would on my Dart with out any issues?
I was thinking of 225/50/17 all the way around but do you all have any opinions?

BTW the look-a-like rallye wheel is steel wheels off a late model Charger/300/Magnum. Then use BBP rallye centers. And lastly 17" chrome trim rings. The wheels are 17x7 with 4.25" Backspace.





The rims are 17x9 Charger/300 steel wheels
Fronts are 225/50 17 Nitto NT450's
Rears are 275/50 17 Nitto NT 450's
A body rear axle with 1/2 inch spacer to clear springs
