Tire sizing dilemma on my '70 Dart

[Dart Frog]

There is a lot of variables when maximizing rear tire on a 70 Dart. I don't even think they're all the same and could vary a quarter of an inch from one to another. I know that my body is not perfectly centered on my tires it has about a half a centimeter to one side bias. But a 7 in rear rim with the right back spacing will give you the maximum tire spacing. I have run both seven and eight inch rims on the back and 8s will definitely spread the tire just enough to make a difference and rub sometimes with certain combinations where 7-in rim won't. It's also very important on the height of the tire taller profile will need you to set the car up higher on maximum tire width. I run a 275 50 15 on 8 in rims on mine with everything pretty maxed out. It takes a 3-inch leaf spring over Arch to accommodate. It's more of a street strip look and would probably rub with anything more than a child in the backseat.

I have not used the vender I posted above, but a few friends bought that tire and other than name look just like BFG. I go black wall out so would not matter. My tires age out before wear

That was never the goal

It looks like I have a buyer for the 235s so it’s not going to be an expensive change of plans.

Fair enough I was just letting you know how far you could go. So at 245 is a piece of cake unless your back spacing is very heavy towards the fender.

I ran 205/75 R14 Coopers on the front and 235/60 R14 Cooper Cobras on the rear of my 70 Dart for years without issues. I also ran 225/70 R14 on all 4 corners for a time, but the front tires would rub the frame on full turn. All on sbp rallyes.
My brother's 68 Dart GT has bbp 15 inch rallyes and 215/70 front and 255/60 rear BFG, previous owner did some minor clearance on the rear wheel openings, no contact issues.

235s on 5.5" rims doesn't look right. The bulge is crazy. I know people do it but I just can't.

I looked for E70x14 everywhere and none to be found

These fit in the (modified) stock wheel well, with the right narrowed rear end and backspace
