patriots781

Ok I found spacers how do I figure out the size

patriots781

235 60 r16 100 are the. Chrome american racing how do I figure out what size spacers I need?

First, it is extremely important when buying wheels to make sure you have the correct bolt pattern and backspacing/offset before making the purchase. These seem like the two factors you didn't look at during this purchase. How are the wheels not "fitting"? Can you not get the holes and studs to line up? Or are you having clearance issues? There are many different things that can contribute to a wheel not fitting. Unfortunately you cannot pick any wheel you like and put it on your vehicle.

patriots781

There both 5 lug just like mine but it doesn't the screws aren't long enough for the new rims

GreggymacZ28

5-lug doesn't mean anything. That doesnt mean that each of the lugholes on the wheels are equally spaced apart to the studs on the vehicle. Without pictures or more accurate information i'm not sure there is a lot anyone will be able to do for you. If I were you I would do a little research on wheel basics. It will give you a lot of information and you will realize there is a lot more involved then 5 holes being in the wheel.

http://boston.craigslist.org/nwb/pts/4313185070.html these are the tires right here I'm trying to find what size spacers ill need

GreggymacZ28

I have seen in another thread that you were having some suspension issues. Have you figured this out yet? I will have to agree with the others there and say that you should do some research on some of these questions you are asking. Forums have really great information, however you can not receive that information without a decent question. Unfortunately, I am having a hard time understanding what you are saying is wrong when you mention the "screws" (I'm thinking you mean studs?) are not long enough. Now when I read this I am thinking the wheel fits over the studs just fine, however you cannot get a lugnut on far enough. But I am pretty sure you mean you cant even get the wheel to fit on to the hub of the vehicle period?

Also, both wheels you posted are after market wheels that most likely will not be able to use the stock lugnuts you have on your vehicle.

I'm trying to help you but you need to do a little research on your own first and then you will find everyone is a lot more welcoming. I hope this helps you.

patriots781

Thanks ya I meant studs sorry ya i mean the rims I have on now same distance between them 5 inches when I go to put the rim on it ( the orig screws coming off the base)doesn't stick out far enough for me to screw the studs on my buddy said I can get a drill bit but I just honestly can't figure out how to calculate the differential for the spacer and my suspension is fine I just had to get use to the car in the snow and when I said that my power steering belt was off so if anyone can help me with the spacer calc please

patriots781

Please help

Are you saying the bolt spacing is 5 inches?

Why would you want wheel spacers if the studs are already too short? Is the mounting pad of the rim fitting flush against the disc brake rotor on the front and the drum/disc on the back?

The chrome rims in the link you posted look like they need special wheel nuts that are long and skinny that fit down into the holes.

somehow i'm very happy that i dont live any where near massachusettes.

be safe and think of others on the road.

patriots781

The studs on the adapter will be long enough

If you're saying the bolt pattern is 5x5 then they will not fit. Our bolt pattern is 5x4.75.



Bolt patterns are displayed in two sets of numbers. The first is the number of studs, the second is the spacing. 5x4.75 is our cars. A lot of Chevy trucks use a 5x5 pattern. I think the 90s Impalas used a 5x5 pattern. Mustangs use a 5x4.5 pattern. Many BMWs use a 5x120mm pattern. A lot of Hondas and imports use a 4x100 or 4x115 etc pattern. So measuring these things is important.

And i have to agree with the other guys, I think you may need some lugnuts like these:

http://www.summitracing.com/search/d...at-style/shank


Which? I have no idea. But you need to look at where hte lugnut seats against the hole. Is the lug nut hole countersunk? Or is it counterbored?



Factory wheels are countersinked. They have a beveled edge taht the tapered side of the lugnut seats into to help center the wheel properly.

From there you're going to have to measure.



This isnt really something we can look at and tell you. You're just going to have to measure.

Adapters will take up the space between the backspacing of the rims and your hub. In effect, they will thicken the mounting pad and put your wheels farther out where they should be. I think THIS might be what you're saying about the studs being too short?



But if the bolt pattern of the wheels are different than your hub you will need to get an adapter that will convert the bolt pattern while also extending your hub outwards.

Also, is there NOTHING written/cast into the back of the wheels that might say what the bolt pattern and backspacing is?

patriots781

Ya there 4.75

patriots781

10mm spaces I think

I watched a video and got 10 inches and 7 and you divide by 2 254=10 in and 177.8=7 in the end I got a 50.8 differential

Dont confuse backspace with offset. Both are useful in different situations but if you need an adapter you will need to find the backspacing. Easiest way, probably, is to measure from the out side edge of the rim to the mounting pad somehow. Put a straight edge across teh front and measure down to the pad where it sits against the hub. Then do the same for your factory wheels. The difference SHOULD be the adapter thickness you need if my logic is right.... This wont work with all wheels, but since your wheels are narrower than factory keeping the face of the wheel where the factory wheel sat is just fine. Also I dont know if you've got factory 15s or 16's, but they're different, also. And 16's are different front to back. You can just use the front backspacing on the back and be fine, though, if you're measuring off of 16's.

When looking up these numbers I found...

None of which have the 5x4.75 bolt pattern you claim they do. Make sure you actually figure these things out instead of having the "Please be right" car syndrome. A lot of people seem to want to have made the correct purchase so badly that they convince themselves something is right when it is not.

Also, I may have missed this, but if in the case they are the correct bolt pattern, you said your issue is the studs are not long enough? You mean this in what way? Maybe if you could set the wheel on the hub of the vehicle and take a picture we would be able to see what you are asking more clear.

Also Infernal Vortex has included some really good information so far on wheel basics, make sure you read and reread his posts so that you can really know what is going on.

EDIT: One of your numbers is missing in the product code, but I am thinking by how close this one is that this may be the wheel you have?

In which case you have a 5x100 bolt pattern and a 5.66 backspacing with a 42 offset.

patriots781

Damn so does that mean there 5in and not 4.75 and say they are can I get an adapter for the spacing and the bolt .25 inches I'm so damn confused with all these numbers and if I get spacers that are too bolig the screws will just sick out a little more and how much $$ are they I went to 2 auto places neither new anything

89fast5oh

1. Those black rims are bent to **** with flat spots. I wouldn't use them even if they did fit, which they don't look like they will.

2. Yes you can get adapters that go from 5x100mm - 5x4.75. You can get adapters to mate almost any bolt pattern. Adapters are anywhere from $60-100 EACH and you need 4. The thinnest adapter you can get is 3/4" and they go up to 2". The adapter WILL NOT have studs any longer than your stock ones unless special order = $$$

3. You still need to ACTUALLY measure the backspacing and offeset to see if those rims even fit on your car before buying anything else. Refer to the above post on how to measure the rims properly.

4. Only when you have REAL measurements can we help you. No point in guessing if they will work.

patriots781

10 inches from the bottom and 7 from the holes

patriots781

I got some pics I believe there 4.50 I'dk

patriots781

Has anyone used http://m.aliexpress.com/item/6049260...il#description and say if the adapter is to long as long as its not short it'll work right because I cannot figure out the length I need

patriots781

Offset is 42 hub bore 70.6 its 10 inches from bottom and 7 from rim holes anyone tell me factory numbers ???

patriots781

Does anyone know the length of the studs on 91 firebird ?

patriots781

I meant the 5 lugs the length,so say I get 2inch spacers and the length is less it wont fit right?I just don't know how the spacers work

patriots781

I can't figure it out so I'm just gonna get the adapter/spacer 2" it's not gonna hurt if there too big as a width http://m.ebay.com/itm/390696249510?nav=VI

In your case, you might be better off taking it to a tire shop and say "Make this work" rather than making a possible inaccurate measurement.

Also, it can hurt in a cosmetic way if your adapters are too wide. You may find your tire sticking outside of the fender, which will look terrible. Unless you have low standards, be confident about what you need before you shell out the cash.

patriots781

I also noticed on one of my drums I'm missing a lug I have 4 instead of 5,looks like it snapped of at some point.

Skinny Neb

iTrader: (2)

That is a very common occurrence. Just replace all your lugs to be safe rather than just the one. If one snaps off, it's very likely that more will do the same.

patriots781

Ok ya I got 2 inch spacer they fit good I wanna get bigger tires does anyone know where I can find the right lug nuts for these rims I think there bullet or billet shaped??

89fast5oh

Lets see some pics of the wheels and how they now fit on the car.

InfernalVortex

iTrader: (4)

With 7 inch wide wheels i dont think you are going to be able to go past 215 or 225. You wont be able to fit 245/50's on there very easily at all.

patriots781

Here they are

89fast5oh

What do you mean when you want bigger tires? Wider or taller? Did you ever get the proper length wheel studs so you can bolt the rims up to your car?

patriots781

I'm gonna put 225s in front 235s in rear

patriots781

When I turn my tires left or right it squeeks and my power steering belt like jumps is this cuz the spacers or if I put 215 or 225s will it stil make that noise?

RedLeader289

iTrader: (2)

To lower that back end, it's sitting way too high (unless you want it that way)

The squeaking is most likely coming from your front sway bar bushings, check them out.

patriots781

The back wheels aren't making any noise its only when I turn the wheel it squeeks nd it feels like I lose a lil power its not steering fluid it happins as soon as I put the spacers on

RedLeader289

iTrader: (2)

I said the FRONT sway bar is what most likely squeaking on you. Take some WD-40 and shoot up on the front sway bar bushings and see if that helps. If not then you need to replace them (most likely they should be replaced anyways ).

InfernalVortex

iTrader: (4)

Turn the wheel until it "jumps". Stop. Turn car off.

Look at tire and fender and see if anything is touching.

patriots781

Ya there is there 225 tires forget 215 or 205 they should fit or I can just exchange the front spacers for 1.25
