Awesome, this link below has always come in handy for me as well when choosing tires:

Done.

+1 to you for the awesome diagram

could you put up a 9.5" with a 35mm offset?

Sure...and welcome to the forum.

added another one.

Thanks, Joe. I like to go deeeep!

how about 8" with a 38 offset, those are popular with VW's

A couple more for curley, and one for you WannaBe. Sorry, been slacking with the update it seems.

Hi is it possible to put a scale on as to how many mm past the face each wheel is.
A + 4 u for your efforts.

Hey Joe, sent you a PM. Just letting you know if you're checking here.

Could you please put up 8.5" with a 26mm offset?

26mm for you

cool thread. My questions answered.

one more for madcurl

Is there anyway to post where the strut towers are in that diagram? Could you also post 8.5" with a 56mm offset and 9.5" with a 65mm offset please?

The red line is an estimate as to where the towers are...may not be accurate. Feel free to send me measurements so I can make it right.

8.5 with a 60mm offset please. Hopefully doing coilovers will get me the clearance I need.

Could you do an 8.5" and 10" with 52mm offsets, please? (Ferrari wheels )

Bob

Could you also put up 8.5 with a 25mm offest and 9 with a 38mm offset (Skyline wheels. Project Corvette Magnesium is looking a little grim due to wheel offset and mod cost ).

Thanks Joe!!

Excellent info source on offsets and tire profiles!! I have printed off both for my personal "Fiero Info" book. The majority of forum postings have really been helpful as I search the archives, finding answers, project info and suggestions. I'm a regular reader, finding most often that I don't need to post a question, since it has been answered at some previous time.

ok, this may be the last time I due this, so can you once again please put up 9" with a 35 offset? I think I've finally found a staggered set of wheels in my style and price range. The rear might require coilovers but that's not too much of a biggie.

Ron, glad you appreciate the info! Welcome to the forum!

MclarenF1..updated with your request.
I also added a colored background with 1" increments for a better idea of things.

Why is that when I try to order rims and tell them I have a Fiero, they immediately tell me the wheels will not fit? Mine is an 1988:

the wheels are

Front: 18X7.5 48mm offset
Rear: 18X8.5 35mm offset

Am I wrong in that they won't work? What size tires should I get?

------------------

1988 Purple Fiero GTw/SC3800 conversion
Best ET with 3.0 pulley,XPHOT cam, SS I/C and 105lb Valve springs: 12.38@110mph
Best 60 Foot ever: 1.699

After some debate I am thinking of these:
FR: 17X7 48mm offset or 18X7.5 48mm offset
RR: 18X7.5 38mm offset


Which set do you guys think will look best?

smaller tire in the front, more MEAT in the rear.

your car is kick a$$ no matter tires you have.

Now get that thing in the high 11s already

good luck

how wide of a tire is safe on a 7.5 inch wheel?

Joe, could you add 19x10 79mm offset and 18x8.5 56mm offest?

is there a offset approx. mid way between 9" w/12mm and 9" w/35mm???

this is kinda helpful

but... the two blue lines, what do they represent? the fender?

how wide can I go with 16 inch wheels on an 85 2M4 and 35mm offset?

They represent the outer edge* of the popular GT stock wheels taking into account the offset(see top yellow ones) so you can judge how far your new wheels will stick out. For 88 fronts, go by the left line, and for 86-87 front & 86-88 rears use the right.

*minus lip thickness

Hey Joe great thread! I'm new to the forum, been watching on and off for a while now and this thread is one of the most useful to me so far since right now I'm looking at buying some new rims and tires... still trying to figure out which ones I want though.

Would like to give you a hand though I think your rear wheel specs might be off a bit... my local custom rim shop (very professional guys with a great setup) has a 15x7 47mm offset wheel listed as the stock diamond spoke wheel for 88 GT, unfortunately they don't have specs on the 15x6 front wheel though so I'm taking it with a grain of salt!

I can only assume that the GT setup is the same as my 88 Formula and last week while measuring my 15x7 rear wheels they were about 1" from the strut and were closer in line with the face of the front wheels than the 15x7 30mm's on your diagram... the 15x7 47mm does match what I've measured on my car better, and looks about the same on your diagram do you think that 47's might be the correct spec for the rear wheels?

so, according to this, I should be able to fit 7x17 ET35 wheels, but not 7.5x18 ET35. Still, I'm worried that I will receive a set of wheels on friday and find that they stick outside the fender when it's time to get the car running...

Does anyone know if it would be ok to put 15x7 with 35mm offset on the front and rear of an 88? I assume it would work but I know the 88s came with the 15x6 in front.
