1964 plymouth valiant with 225/60/15s for the front
I'm assuming that pic is the front edge of the wheel well (hard to tell with the car covered in paper).
I'm not sure about the '64 Valiant specifically, but most A bodies have a fender brace going to that corner of the fender lip- many times you can gain additional clearance by lengthening that brace by 1/2, 3/4, or even a full inch. Play with it to see what works for you. Extending it by an inch or less isn't even noticeable appearance-wise. If your car doesn't use fender braces in that location, it might be a good excuse to add them.
