I fell in love with a set of wheels that were not available narrower than 15x8. For the rear, these have a 0 offset (4.5" backspace). The front wheels have a +10 offset (4.89" backspace).
The car is a '73 Dart Sport with front disk brakes.
I'm looking at 255/60/15 rear (which I'm confident will work) and 235/60/15 front. Would that work or would I need to step down to a 225 on the front?
Thanks for any advice!

Have you test fit those front wheels yet? I've never been able to fit more than 4.75 backspace on the front of E and B bodies with a 15" wheel. They hit the upper ball joint. Tubular upper arms can give more backspace clearance for 15" rims. The factory upper has a lip, whereas the tubular have a straight sleeve. What you could do in the front is just add some steel circle track wheel spacers. They come in 1/4", 3/16" 1/8".... You need to look at lower front corner fender clearance. You can push out that corner for more clearance by lengthening the lower fender brace. May have remove or loosen the lower valance for that. And then see if it will bolt back on after pushed back.

So worst case scenario, a spacer that made up the difference between 4.89" and 4.75" should do the trick?
Thanks again, guys Yes. But the design of the rim may require a little less or more. A cast rim is a little thicker there and may require a little more. Also account if you plan on putting clip on or stick on wheel weights on that closeted edge.

So I finally had a chance to test fit these 15x8 +10mm wheels... so damn close!
3/16 spacers ought to do the trick. Pics forthcoming.
Thanks for the input, guys! Is that with stock upper control arms?

Well, with the stock UCA, the rim hit the trailing side of the arm. With the QA1 UCA, the trailing arm clearance was solved but the wheel hit the ball joint.
I said "eff it" and had a pair of the wheels narrowed. I'm happy with them...surprisingly, the 225/60/15 makes light contact on the passenger side fender when making a sharp turn and hitting any kind of a bump. I'm hoping that max negative camber might solve that? It doesn't hit on the driver's side.
