69 Dart tire size

Would it be better to go with 215 60 15 on the front and I forgot to mention the fact that I will be turning the torsion bars to raise the front on the car a little bit

I plan on rolling the inner fender lips front and rear

A 215/60/15 is kinda short at 25.2”. It would definitely be an easier fit. If your intent isn’t to lower the car, you should be able to run the 215/65/15’s. Rolling the lip won’t do much, that’s good for increasing the width of the tire but with height it’s the lower front corner that’s the issue. It can also be trimmed back though. Honestly I would be inclined to run a 225/60/15, they’re a good height at 25.6”, and put a little more rubber on the ground. I ran those on my Duster for awhile.

If you roll the rear quarter lips the 245/60/15’s should be fine as long as you get the backspace right.
