My "new" '74 Duster- or why I need a project like a hole in the head

18x9 +30's should be fine for the front. Your brake set up should be about the same as mine for track width, mine are +35's but it's a small difference. The other thing is to look at 18x9.5's, it seems like there's a lot in the +30 to +40 range for aftermarket wheels in 18x9.5". And that should be fine too, I'd lean more to +35 with those. If I buy another set of wheels for the front they'll probably be 18x10's.

Really the 275's aren't that big of a deal as long as you've got 6" of backspace. Maybe a trim on the corner and a little lip rolling, the rest is ride height dependent and most folks don't run as low as I do.

I fight with the tire rubbing on my frame rail and z-bar bracket. Just got done drilled a small hole in the lower control arm for a 6mm bolt for the steering stops to hit and now I am clear, but not 0.6" clear. So a wheel with more backspacing and a wider tire is only going to be worse. Not really sure why my car rubs when I know of others that don't have that issue, but it is what it is.

The additional 5mm of positive offset would probably make that RT660 clear the top of my fender with a 9" rim. Really doubt it will work on a 30mm offset rim unless I start pushing the fender around. Not the end of the world to do that, just need to accept it before I do anything. Car is painted but it's not like it doesn't need to be straightened and painted again.

Worst case, I guess I could do like the guy that put +12mm offset Enki's on his Duster. Somehow he got it to work. And I think he even ran a 285 tire.
