275/60/15 woes
There are far more Dusters/Demons/Dart Sports with 275's mounted on them successfully than cars that they didn't work on. The OP's car will most likely be just fine with a 1/4 spacer and nothing else.
I'm well aware of problems in ordering rims, I've maxed out the rim and tire widths on pretty much all of my cars. And when I did it there were very few people running the sizes I run with the axle I have, so it was a lot of measuring, math and straight up guess work. I run 275/35/18's on the FRONT of my Duster and 295/35/18's on the back.
We've done this dance before, you can check all the threads. I'm not going to argue that 275's will fit your car, but I'm happy to provide all kinds of examples of them fitting just fine. I know there are more, but I have better things to do than look up every single example. There are plenty more.
Here's a dozen cars. Literally a dozen. Demon Rear Wheels I know you've seen it before because it was in response to you, but you can follow the link for the pictures or expand the quote for the links to each and every car.

You keep disagreeing and more and more members keep running 275's. Measured correctly they will work on the vast majority of Demons/Dusters/Dart Sports. And regardless, you should ALWAYS measure your own car because the body tolerances on these cars are fairly loose. The ballpark is about the same, but when you're maxing out the wheel well a 1/4" can make or break the fit. And you do have to account for the different width axles, because a SBP A-body 8 3/4 is not the same width as a BBP converted A-body 8 3/4. 7.25" and 8.25" rear axles are different from 8 3/4's too. So you can't just copy one person's backspacing, you have to match the whole combination.

So here's a quick list of a dozen other members currently running 275/60/15's on unmodified sport body cars. I only used examples for cars that the owners said were stock, and had posted a picture for, and I left my car with 275's on it out just in case you think I'm biased. There are tons more folks that have said they've done it without posting pictures. And I'm sure there's even more that I haven't found, but I wanted to limit this to 15 minutes of my time. So, either all of these people are lying about their cars, or you're incorrect. That doesn't mean you have to run 275's, do whatever you want. But it can be done successfully, without rubbing, because they will fit with the proper backspace. And now I can just reply with this post anytime you say they won't fit, so folks have evidence to make their decision.
