Cop car rim size
Yeah the Darts/Demons/Dusters all have these lower fender braces. The bumper end has an oval slot, so you can sometimes gain some clearance at the corner by adjusting the brace all the way out.
For 225/60/15's the most you should have to do is adjust the brace though. If you wanted to make the 235's fit without having the car raised up with the torsion bar adjusters you'd probably have to cut the corner of the fender lip back at the very least. On my car I did that, and also lengthened the lower brace from about 12" out to 14". That pushes the lower corner away from the tire and allows for more room. In my case that's what was necessary for the 275/35/18's I run up front with my lowered ride height.
These are my braces compared to originals. That's about the most you can push without totally distorting the fender and the fender to lower valance seam.
And this is the corner treatment
But that's not the only issue with the 235/60/15's on 15x7's with a 4.25" backspace. That combination actually puts the outside of the tire as close to the fender as my 275/35/18's are, in addition to the 235's being taller (26.1" vs 25.6"). At a higher ride height I managed to run the 275's without rolling my fender lips, but as soon as a lowered the car even slightly I had to roll the fender lips. At my current ride height the fender are rolled, as well as "pushed" out using the fender roller. So what I'm saying is the 235/60/15's are going to be tough to keep up front unless you want to start modifying stuff or raising the ride height.
Pictures don't always capture it, but there is an outward bulge on my fenders at the wheel opening. This picture shows it a little, if you look at the front fenders compared to the rear quarters they look similar. And the rear quarters on the Dusters/Demons are flared out.
My ride height. If you look at the fender/valance area you can also see how the lower fender corner is pushed out and trying to take the valance with it.
