I have a 1985 Fiero that I am restoring and right now I am thinking about wheels, used wheels.
There are many used mags on Marketplace and some sets go cheap. I know the bolt pattern is 5x100
but what I don't know is what donor cars are the most likely to have the proper offset etc. Are there
wheels from another car that are usually a good match for what I want? What I want more than anything
is to find some attractive mags that are wider than the stock rims. Especially wider in the back, the front
not so much.
I know this post is lacking a lot of details but maybe someone understands what I am after look-wise. I am not a fan
of large diameter wheels and thin section tires on that car. Or maybe a post was already created regarding this topic?
Now that would be really cool.
Thanks for all and any help.

PT Cruiser wheels (16”)
Pontiac Vibe (center bore needs to be opened up just a tad)
I’ve seen a few Fiero’s with Beretta wheels.

Volkswagen New Beetle (1st gen) are ideal for Fieros. They are 5x100, with a 57mm centerbore. Most of them are ~35mm offset.
This probably applies to many other smaller VW and Audi products, too. (The earlier Audi TT comes to mind.)
Lots of GM stuff - especially earlier J bodies - will also work. Be careful, though. Some of them have more offset, and will sit deeper inside the fenders than stock wheels. Some of them can even cause interference with the rear struts.
Lots of Subaru and Toyota wheels are 5x100, but they use a 56mm (or smaller) centerbore. They will have to be bored out to 57mm.
There are lots of others. Those are just the ones that come immediately to mind.

Good info Raydar,
Now I am going to hijack my own thread and ask......
What is the max wheel/tire width that will fit in the rear without going to flairs?
I have a method in my madness because I intend to put a boosted 3800
in it after I get the factory V-6 running correctly and get the bugs worked out.
I know by running the boosted 3800 it will need some real rubber in the rear.
So regarding the rear wheels. I was thinking of using 15" wheels as I think
that low profile tires look odd on the car and the increased tire section of the
smaller wheel allows more latitude in an old suspension design, and a less harsh ride.
Thoughts on this?

I agree with not going with 17-and-up wheels on the Fiero. Sadly, it is hard to find 14-15" performance tires. I went with some VOXX Monza wheels in 16 x 7 size with 38mm offset- they fit well, and that offset helps to counter the heavy steering and kick-back. The VOXX Monzas are no longer available- but other companies produce this size...You can also go with a bit more offset; Originally Fiero 15 x 7s were 30 mm, so the Monzas are 8 mm farther in....if you went to 48 mm up front that would move the tires inward another 3/8" (approx)...Using the same offset in back would be ok- just go to longer studs and use aluminum spacers.
I went with 205/55 up front and 225/55 in the rear...These were common sizes in the 90s for many popular cars, so a lot of options from many tire companies. I have been using General G-Max all-season tires, which rate highly in TireRack testing and also are lighter than most performance tires.
Remember to stay as light as possible; I eliminated 3 lbs off each rear and 6 lbs off each front- the car felt and performed much better.

One of our members had Lexus SUV wheels on one of his Fieros. Also, Hyundai Elantra wheels are same lug, center, and offset as the Fiero, as I have been told. As Raydar indicated, some wheels require the center to be bored to 57mm and others require a wheel-centric ring for center-bores that are oversized. That ring is very important to keep the load off the lug studs.

I've seen some seriously wide wheels on the back of a Fiero.
It depends upon the offset, and what you consider "sticking out too far".
The point of interference on 84-87 cars is likely the strut. Or the part of the strut that sticks out from the spring perch. Coil-overs will pretty much eliminate this issue.
88s tilted the struts in farther, so it's not as much of an issue. On those, the trailing link that goes from the bottom of the knuckle to the front of the cradle is the most likely interference point, with the inside edge of the wheel/tire.
Fieroguru has a great deal of information regarding what works. At least on 88s. He's got some very wide wheels that fit under the car quite well, but he's also done some serious mods/fabrication to achieve what he wants. (He's got a turbo LS4. So I know he needs some serious bite.)
I have 17x8.25", 35mm wheels on the back of a nearly stock 88. The tires are 235/45-17. They fit fine, but I also tend to be a bit conservative in my wheel choices.
245s would probably fit, just as well. (I know for sure that they'll fit on a 17x8" wheel.)
