I love the wheels and tires pictured below. I IMd the guy who bought them in the mall and got no reply.
With the exception of lowering I have a dead stock 87GT I would love to put this combination on. How do I know what will fit and look good? I believe these are 18" in front and 19" in rear.
BTW- I still use stock-type struts in the rear.
The first thing you need to make sure of is that the offset is correct, and that the bolt-pattern spacing is also acceptable for the Fiero. In terms of fitting under the wheel well, you want to measure the sidewall height of the tire, double it, and add it to the diameter of the alloy wheel. Then, take a yard-stick or a tape measure and see if that will fit in your wheel well, both vertically from the ground to the top, and horizontally (front and rear of the opening of the tire well).
The Fiero wheel openings are actually quite large, really... so you can usually fit large tires in there. Same goes for the front, although if the tire is too wide, you'll rub the plastic wheel wells (and inner frame) when you try to turn too sharply.
Yes- the size is 18" x 8" with a 38mm offset. From the Joe Torma diagram it appears they will fit my 87GT OK. May stick out a few millimeters. My biggest concern now is tire choice and rubbing of wheel wells and struts. My 1987 has the Intrax springs so it is lowered ~1.8".
I highlighted the size of these wheels in yellow.

All that being said, how can I determine how much meat I can put on the wheels without rubbing?
Hmmm, Since Jazzman physically measured the offset between the wheels in question, Then the OSG specs are incorrect. (I am going to edit my post above to reflect the proper offsets)
As for tire sizes, The largest recommended size of tire for an 18 X 8 wheel would be 235/50R18 but it will rub the strut with a wheel offset of 35mm or more. For a Fiero the best size would be 215/40R18 as long as the offset is 40mm or less. For the 19 X 8.5 wheels, the best size would be 225/35R19 as long as the offset was 30mm or less.
Have you measured the wheels yet? What size tires are on them?

OK. Got the tires and wheels mounted and put them on my 87GT. I love them. The only thing that "sticks out" (literally) are the wheels in the front. Not by much, grant you, but I can notice it.
Seeing what it would look like on the diagram above does not give you a good feel of how they will look on the car. This is why I would be really wary of putting these same wheels on an 88. I know they would stick out too much. It is a shame because I would love a set just like them for my 88 as well.
How can I get a wheel just like these with like a +55 offset for the front?
