69 Dart Rear Tire Size

I have been looking and looking for what the widest tire size is for a stock Dart. I am wanting to know what the widest tire with stock spring location and for relocated springs.

I saw in the Tech Pages where they show the springs being relocated but it shows with the wheel wells widend and it shows a 12.5" tire. I don't want to modify the stock wheel wells.

I have some Centerline Auto Drags for the car that are 8 1/2 wide and 5" backspacing. I used to run this same size wheel on a 'cuda and also on a Challenger w/295/50/15 with no rubbing. (attached photo)

I am sure I cannot go with a 295 with just relocated springs but I would like to run the largest I can.

Any help, photos, links to pages or threads about this will help.

Hit the top right hand button for the Old Forum. Once there go to Engine Drivetrain forum. There is a sticky topic at the top that is 4 pages long. Alot of us posted our tire and wheel combos to help each other. Tom
I'm moving my springs with the 7/8" kit and I'm not cutting the car. So far, 235/70/15's on 6 1/2" steelies fit great.
Lots of info
Here is exactly what I was looking for and I think that this will be plenty of tire.
