1973 Dodge dart Bbp wheels and discs on a 1969 Barracuda

My second gen Barracuda will accept a tire up to 25 inches tall and up to a 235 on a properly back-spaced 7.75" wheel, (what I have lol), into the stock wheelhouses even lowered with the K at 5.5" off the deck.

After that it gets a lil dicey.

A 245/50-15, on an 8 is guaranteed to nik the front corner on the fender and rub the frame at full lock, on the backside. No matter how perfect the backspace .

You can put an 8x15" steel wheel on the front, but you will have a dickens of a time centering it on the scrub radius, and so no matter how you align it, she will want to climb up out of ruts on an asphalt road, and feels like a constant tugging or wander. Furthermore, if you do get it centered, it will rub on the upper BJ at or before full droop, and the BJ will tear off your crimped-on wheelweights. And yes, it will rub on the strutrod before it reaches full lock.

In other words, after much trying I got a 245/50-15 on a steel wheel, to work. But I had to trim the fender corners, shave the upper BJs in just the right places, use stick-on weights,shim the spiders just a hair, and reset the camber several times. And I could not cure the tendency to "wander". Those tires were 24.6 tall..
Now,
a 235/60-14 is 25.1 tall and fits just fine on a 7.5" aluminum wheel with no mods required. IIRC my backspace is 3.75.

The point is this;
Those late-model brakes, push the wheels out just a lil further, and
your 215s could be nearly 28 inches tall depending on the aspect ratio,
and your wheel could have a reverse offset, we don't know.
So before you get your knickers in a bunch, lets get that sorted.
