Help with my wheels 68 Dart

Rim diameter or size isn't the important fitment issue. It's tire diameter and width. You can have a 17" rim on a wheel that is the same diameter as your current 13" wheels.
A wheel is a tire on a rim.
A 205 70 14 on a 5 1/2"wide rally rim will fit on your front drum brake suspension and not rub

I suppose I should clarify... the plan is to run a 5 x 4.00 bolt pattern 14 inch wheel / rim with (at the largest) a 205/70/R14 (Maybe 195 /70/R14) tire.

Seems like there has been some confusion, my 5 x 4.00 bolt pattern is the SBP. a 5 x 4.50 bolt pattern wont work for me, since it require changing out the bolt pattern from my vehicle all the way around since the 5 x 4.50 / 5 x 5.00 is the LBP.
