I bought a set of Cavalier Z24 wheels a few months ago. Put some tires on them and they seem ok. However the wheel is only a 6" wide rim so that limits what size tire I can put on them. I was looking at Craigslist a few minutes ago and found these.
I also noticed with the cavalier wheels the back seems to sit in the wheel well further than I'd like. Would these fill out the wheel well better? I was thinking of putting 225/50 or 55's.

I've run these 1" hubcentric spacers on the back of my '84 duke, and then on my '88 Formula, for the last five years. They bring my Sunfire wheels (same offset and width as the Cavalier wheels) out to the edge of the rear fenders (instead of being tucked in too far).
No loosening of lug nuts has occurred after being torqued down properly, and no added vibration at high speed
205/55/16 tires on the front, 225/50/16 on the back.

The offset is different. You have to be careful that wide tires don't rub on the rear strut, as the rim may be very close to the strut already. A solution is to use a spacer, as mentioned. I would do this instead of trying to use tires to make them stick out more.
What I want to do is be able to run a wider tire after I do the swap. I doubt the 205/50's will have much grip. This is why i wanted to go to a 7" wide rims so I can stick a beefier tire on it.
I could get the spacer which isn't a bad idea but I'm not sure how wide of a tire I can stuff on a 6" wide rim. I've googled and the cavy peeps are running 225/50/ on the same wheels.
I've used 16x7, 38 offset, with 225 50 tires before without issue. The tires are close to the struts in the rear but I had no problems. The wheels you're looking at on craigslist should be fine. I wouldn't use a 225 on your current wheels, though.
Sometimes when talking about offset and backspacing the terms get intermixed with eachother.
"Offset is the distance from the center of a wheel to its mounting face" "Backspace is the distance from the inside edge of a wheel to the mounting face."

Simple rule for tires is the tire tread should be close to the width of the rim. You cant put an 8"-10" wide tire on a 6" rim. You need an 8"or 10" rim. If not it will wear fast and funny, handle terrible and be lucky if it dont pop off the rim in a corner.

I don't have those anymore, but they looked fine. 35 offset works well on the Fiero. In fact, I believe the factory 15" GT wheels are 35 offset, maybe 30 which isn't much of a difference. They're about even with the fenders.
Here is the Fiero wheel info chart I found here a while back. I use this often when planning and helping others. I don't remember who put this together but they deserve some major Kudos
