68 cuda wheel FRONT

15x4” with a 2” backspace?

Anything wider than a 195 will hit the fender lip, not enough backspace.

Barracuda’s have pretty small wheel openings, usually guys have to modify the lower front corner of the fenders to fit anything taller than 26” unless the tires are tucked well into the wheel wells. Which will take more backspace than you’ve got.
