I am looking at getting a new set of rims as mine are in need of refurbishment. I figured I would buy a set while I decide what I am going to do with my wheels. I have a 1986 gt. There are lots of posts about rim width with a debate between 6" and 7". Some websites say OEM size is 6, but others say the rim is a 7j. I have pulled off a rim and there are no no identifiers stamped on it other than made in Germany and some other numbers, none of which are 6 or 7. I have also read that the size was raised on the back of one of the honeycombs, could not find that either. I did clean out all of the brake dust to see if there were any stamps hiding under it. My do it yourself manual says 6" wide rims. Is there a way to confirm such as a code on the spec sticker under the front hood? I want to use my stock 215/60 and 205/60 r15 tires. Strange that I could not find a size stamped on the rim. Any help is much appreciated.

The 88's run 15x6 in the front and 15x7 in the rear. The 86-87 run 15x7 all the way around.

If you buy an aftermarket wheel, be aware of the wheel's hub bore. It needs to be at least 57.1mm

In regards to hub bore, can it be greater than 57.1? I think you use hub rings then, but I am not an expert.

That is true- they are called "Hubcentric"......You can order different rings to match your hub-wheel interface.

Regarding the stock Fiero "mesh" wheels...
If it has a 1" horizontal lip between the spokes and the edge of the rim, it's 7". If it does not have that lip it's 6".
