Biggest Rear tire setup on stock 68 dart 14" wheel

After rolling, I can fit my hand between the tire and body, and they do not rub at all, unless i go over a bump, while driving fast, and turning right. SO not often at all.

I'm going to have the springs redone in the back so the rear end is not tilted over to the right. You can kind of see where the body eclipses the tire a little too much on that side.

But I'll agree with those before. This is probably the biggest tire that will fit under here.
