whats the largest wheels you can fit on the back? I would like the widest tires possible, and rims that fill the wheel well nicely

however at the same time if tires are $400 each I might pass the idea lol. so maybe the best price/size options too

I have an 86 GT, plan on using coilovers

thanks

20x9.5" max using a 275/30/20 tire.








The key is keep the top of the wheel even with the top of the fender lip.

What size are these? I think they fit this car pretty nicely.

That's not a stock Fiero. (But the door does open.)

i am running a 19x11 rear wheel with a 325/35/19 tire on the rear of my mera

I know, I drooled over it at the Tyler Shipman Memorial Show.

for the record I looked it up.

23.5x10.0R16 GOODYEAR G19 race slicks (front)
25.5x14.0R16 GOODYEAR G19 race slicks (rear)

If you're not wanting any fender flares or widebody kit, 17x8 front, +45mm offset, on 235/45, and 17x9 rear, +45mm offset, 255/45R17, according to WCF, IIRC.
Anyway, a 26.1" tire looks very good on the back, and a 25.3" tire is plenty for the front. On 15x7s, that's a 235/60 rear, and a 215/60 front. You can fit a 245/60R15 on the rear, if you so choose.
If you're wearing 16x7.5 wheels, a 235/55R16 would be good in the rear, and a 215/55 up front.
Beyond 17s, the options get pricey.
Search "Joe Torma" to find a schematic of how different wheels will sit in the wheelwells.

Didn't you see madculr's post above? I have 18x9 35mm with 265s in the back with no problems.

I run 33.0 x 21.50 x 15 's on a 15 x 15 wheel. But, there is a 9" rear end involved.

First, Madcurl went beyond the "budget" part of what the OP wants. Second, your pic proves your outer sidewall bulges aren't even close to being inside the stock fenders, only your tread barely is. You would need another 10 mm of positive offset, which might require some grinding, or worse. Better to drop back to 255s to sharpen the cornering response slightly, or 245s to make it noticeably more predictable at the extreme limits of adhesion, plus dramatically improve recovery.

Hey Curly,
How've you been? I've got 2 Questions for you.
1st Is your car an '88, or an 84-87?
2nd Do you remember either the offset or the backspacing on those 9.5" wide rims?

Hope you're doing well.
I still haven't gotten my LS376/480 fully sorted out yet.
She's still running very rich. A/F ratio in the 11.5:1 - 9.3:1 range.

What year ? Will you install coil overs? You can fit an 8.5 rim with an 88 and coil overs.

He said " fill the wheel well nicely". Not keep it 100% inside. He may be fine with it like most that like my setup. Yes madcurl's are high budget. Then probably this one too. If you want cheap wheels then you may need to stick to 8" or less.

I'm doing great Bob. Thanks for asking. I'm sorry to hear you're having minor issues with the A/F ratios. Hopefully, you'll get the Fiero rolling soon. Now back to #011. It's a 1987, so the 9.5 might not fit due to the 88 newer suspension set-up. However, this week I'll take pics of a 9" rim thats on #020 (which is a 1988) and see how it looks on the rear of a 88. You might be able to squeez an additional inch on the inner (more if you have coil-overs), but I doubt likely on the outer lip.

Here's a pic of #011 inner barely clearing the coil-over.

Barely clearing the coil over


You could squeeze more inner lip if you use shorter springs like V8Archie did on Troyboy's 1987. Please get in touch with me if you want the HRE wheels in the future. I know Vince @HRE and he's very helpful in getting the best wheels for your ride. HRE is very tight lipped regarding their wheel specs, but I do know how to read the measurements, but it's not 100% sure thing when appling HRE spec on other brand wheels.

Alex's red fiero probably has the best (non dub) looking wheel setup that i have seen on a stock fiero.

The size fills out the wheel well nicely and the stance could not be more perfect.

This is member Nosaint's car with 19x8.5 in front and 19x9.5 in the rear:

quote Originally posted by nosaint: thanks guys for the comps. This is the first time I have purchased a semi completed car. Rims are MRR GT1's in 19 x 8.5 9.5. Already lowered with rebuilt engine and T3 Garret intercooled Turbo. 12" 4 piston fronts and larger vented disc in rear. Car needs some love and I'm currently working on fixing up the interior and getting a few little things going that don't work. I am impressed with the amount of interest this car attracts, very rare around here

I ordered the coilover sleeve and adjustment nuts

so with those what would be the best bang for the buck rim/tire combo?

I'm not sure if the sizes posted already were considering the stock spring width ect

looks great but I'm looking for what should fit my car.. those struts seem to be mounted at angle doesnt look like my suspension.. or is that an 88?

I have P295/50R15 105S on my 84 IMSA with what looks to be 1/4 inch wheel spacers on the rear wheels so they dont rub aganst the caliper, These rtires are up in the $300+ range but when you get this big your going to have sto do some body mods or an IMSA kit depending on your local ordinences.



Thoes wheel chucks look dinky on thoes things.

Scott0999 - sorry...those probably wouldn't fit, that's a custom cradle ('67 Toronado cradle) that he built so the tires would fit within the stock fenders.....the wheels themselves are 18x10 Boyd Coddington Shrikes....

What about with lowering springs and regular, non-coil over rear struts.. would that severely limit larger rear wheel size?

quote Originally posted by tbone42: What about with lowering springs and regular, non-coil over rear struts.. would that severely limit larger rear wheel size?

Yes. A full spring will limit your size as the wheel / tire will hit the spring perch. Coilovers have shaved perches, so you don't have that issue anymore.

coilover it is, then!
