Has anyone actually managed to mount a decent size tire on a 10” wide rim and get it entirely tucked in in the back without much inner wheel well work? If you did what backspacing/offset/wheel/tire did you use? Any pics?

AlkyIROC

10 x 15" rim with 5.5" backspace. How much tire will fit depends on how tall and wide you want to go. A 26 x 10.5 ET Street fits with no problems. So will a ET Drag 28 x 9. Drag tire widths are different than DOT tire widths.

I now have a set of ET Drag 29.5 x 10.5 slicks stuffed under my fenders but also have a few inner fender modifications.

Basic inner fender mods are like this. (not my car but mine are similar). You cut off the bump stop and reweld a plate over the hole. The front of the inner fender needs to be sectioned to allow a taller tire. My front of the inner fender isn't modified like this but the lower part of the inner fender below the floor is cut right off including the section right at the front.

Any pics of how those wheels actually sit in the wheelwell? THAT IS EXACTLY the backspacing that I suspect will work the best, but in recent days/weeks I’ve heard enough other stuff that I’m starting to wonder, as well as people claiming that you really can’t properly tuck a 10” wheel on a 3rd gen, which I don’t believe…

While I’m thinking about it, that level of modification of the wheel wells is, what I would consider rather minimal, but one thing that I”ve wondered is that with all of you that have removed your bump stops, have you replaced them with something?

The only question I can answer is Yes I plan to replace the bumpstop.

anymore pic's of that car above. I like how he did that. To bad I already got rid of my complete wells.

and here it is with 18x10.5's i kno ill try n get more pics

Camaroguy18

really whoring those pics around huh? .........anyways, I get what you're saying about tucking with no mods....and the only thing I find odd about it all is how some people can have the exact same setup right down to the type of rim, and for some it will be minor mods, and others a ton more (granted suspension etc plays a role). ......and just out of curiosity, when you say 'decent size tire'....what size are you thinking (generally speaking)

83 Crossfire TA

iTrader: (2)

Well, in this case I was thinking about something with a section width of around 295 and in the range of 26-27" tall...

Hey dan, go back to the ZR1's, they look much better.

Do you know what offset or backspacing you ended up with (I'm assuming that you're running a spacer with those rims, and I don't know what offset you started with)? did you have to modify the wheel wells at all? any pics of the car from behind?

BTW, I _really_ like the silver/gray color…

FSTFBDY

iTrader: (33)

I agree with Mark,

I like the ZR1s better. Maybe because Im biased and picked up some 17x9.5 SS rims. with 275/40/17. Id like to find 2 17x11's for the rear and go with a 295 or 315 though.

Camaroguy18

I wasnt hating on you or anything, just joshin ya cuz I saw those same pics on 4 consecutive threads....by all means show that thing off

295/35/ tucked... very little massage and requires the complete removal of the rear bumpstops but with a 6.75 bs it's the right way.

18inchboyds

hey jeff since you cut the bumpstpos did you use the bumpstops that go on the shock shaft and area bumpstop or just not use one.

83 Crossfire TA

iTrader: (2)

On what width rim? 10", 10.5"?

Kandied91z

iTrader: (7)

technically it wouldn't matter as it's the tire your fitting but to answer your question 10". my normal street tire was a 285 but bfg only makes dr's in 295's in an 18" so that's why i had 295's as well.

18inchboyds- no bumpstops in the rear. what i said of course is for low profile street tires. not all out slicks like mentioned above which requires alot of work in that area.

mw66nova

iTrader: (13)

hey 83 Crossfire TA,

what do you want to do with the car? at first, i thought you were going with a 15x10 with a drag radial or slick, but now, i don't know what you want.

83 Crossfire TA

iTrader: (2)

Sure it matters, 5.5” BS will be 0 offset on a 10” rim, where a 5.75” BS will be a 0 offset on a 10.5” rim. The offset determines how the tire sits in the wheel well, not the backspacing (independent of the rim width). Your wheels appear to be somewhere in the range of a 1” (25mm) offset which is HUGE on a 3rd gen.

Yea, but it gives me a good idea of what fits where. Like I said, I wish I had some of these cars near me or at least some of these rims/tires around so I could take some actual measurements.

Nutsell… street tires.

Long winded answer:
- not much that is going to fit in that wheel well, drag tire wise _really_ needs wider then an 8” rim. 8” is lighter then 10” so there isn’t much reason to worry about it there unless I’m doing it just for looks
- I hate low profile tires, yes, I own some and (my ’97 WS6 came with what I think are some of the better looking 17’s out there), that doesn’t mean that I like what they do to the handling (and yes, I mean handling. In most cases your unsprung weight goes throught the roof with larger rims and handling suffers. You also loose slip angle before break away with shorter sidewalls which hurts if you intend to keep it controllable at the very limit). I also don’t feel that tires that stick out are a very “street” look even thought they can be made to work. So I’m trying to figure out what exactly will fit in the back on these cars and choose accordingly (there is actually a market out there for 15” tires that handle… with the Pantara guys, classic Ferrari, cobra, gt40…). Right now I’m looking at some 295/50 _IF_ I can get them completely tucked into the fender on a wheel wide enough to actually properly support the sidewalls (IE, if I was looking for drag use or just tooling around this would be easy, stick them on sme 15x8’s with about a ˝” offset and everything is happy). If there is no way that that will happen with the fit that I want then the next step down is something like a 275/50 (nitto 555r’s actually handle GREAT for autox and similar use), but there isn’t a good, matching choice for a front tire size that isn’t taller then the 275/50 so I’m trying to stay away from that.

Make sense? Its basically a super **** retentive quest to get EXACTLY what I want.

Oh, and Kandied… I do think that you have yours about right (hard to tell from the pics), if anything maybe a little (like Ľ”) too much in, but it does give me a very useful data point since I haven’t seen anyone running a taller sidewall, wide tire tucked in like that at all.

Kandied91z

iTrader: (7)

lol... one thing you'll learn, you can't truly guage anything from pictures. they are just nice as a reference, starting point. you'll figure it out, somehow.

JeffW

umm 10" x 17

i think the bs was 5.75 no mods needed and the car is lowered with eibach pro

Kandied91z

iTrader: (7)

5.75 is a very popular back spacing. i originally had that here. but the wheels were 1" further out then the fronts. i later had them re-hooped. you can see the difference by the reflection of the sun. still fit very nice but would not work for lowered vehicles with a 295, the 285 was pushing it but worked. could have fixed that by rolling the quarter some though.

drain89

iTrader: (10)

I'll be running 17x10's with 6.25" BS. Should put the rim right where I want it....gut I'll have to roll the lip and "massage" the wheelwells. Probably remove the bumpstops too. My rearend should be here this week. Then I'll be able to mock things up.

Mine measure 11" wide from outside edge to outside edge. The guy I bought them from said that you don't include the lips though. That would make mine 10". Is that right?
My fronts measure 9.5" wide with a 8.5" actual.
I always thought that if a rim was 11" wide it was 11" wide.

Kandied91z

iTrader: (7)

yes it should be, not sure what he is talking about..

83 Crossfire TA

iTrader: (2)

JeffW- thanks for the pic, it’s actually a perfect example of what I’m talking about. Not to pick on it, but to _me_ that kind of stance looks way cool for a couple of days and then you start wishing that it tucked in better. That and it doesn’t play nice with taller tires and lowered ride heights.

Drain89… how long till you have those things mounted? I’d love to see some pics. The best that I can figure, 6 – 6.125” backspacing will put a 10” rim exactly where the stock rims go (6 will be like the stock 15x7’s, 6.126 will be like the stock 16x8’s), and I’ve been thinking that going somewhere in that to 6.25” backspacing range will be the magic number. With 6.25” that extra 1/8” – Ľ” BS will just tuck a wide tire in enough so that it looks like a “stockish” fittement (the outside edge of the sidewall of a 295 should be at right around the same place as the outside edge of a stock front on the back), and if it proves just too much backspacing to wedge in there easily that extra fraction of an inch can be adjusted for with a thin spacer.

Oh, and yes, drain, you got your numbers right.

Now I do seem to remember Andris or someone saying that more then 5.75” backspacing hits something on the back, anyone know what the deal is there?

Here, this will help at what I’m getting at… this is a pic of an old car of mine with 235 and 255 60 15’s on it (26 and 27” or so tall tires). It sat about an inch or so lower all around then my formula does on 245 50 16’s (about 25.5” tall tires, if that) and the typical eibach pros… (and yes, I saved the whole suspension from the old car).

That’s about the stance that I’m after, but with the front tires out about Ľ-1/2” more then those are. The front is easy, the back, well, I’m thinking that a 295/50 is within about ˝” of the 255/60, so if I can get it to tuck in right I can get the same look from every angle except from behind (where it would look much better).

drain89

iTrader: (10)

I don't have the tires yet, but I do have the rims, my rear brakes, and the 12 bolt (which is the stock 82-92 width) should be here sometime late this week. It'll probably be a few weeks before I can do a mock up to see how things fit.
Even without tires I should be able to tell whether it'll work or not.

Wow, I attached a smaller, lightened version of that pic to this post so people can see it easier.

Thanks for the pic, that is EXACTLY what I’m trying to avoid (not picking on you, if you like it it’s your car, but that’s not what I want on my car). I like how the tires fit on the wheels, but not how the wheels fit on the car. About how far do you think that they stick out of the wheel wells? That is about 1” off of what I was thinking would be a good fit for those tires, but from those pics it looks like they stick out more then an 1”, is that right?

mark,

here are some OLD, OLD photos I dug out to take a pictur of for you. Thats why you see the scratches etc. Photos of poliroilds. I had this 83Z back in '95

The rims are 15x10 with 295/?/15 I forget the height.

I dont rem the backspacing either. I traded a sony 4channel amp I had to a kid with a S10 for these rims. They came off his 89S10.

They tires edge was even with the lip. They did rub on a good launch or taking a corner fast. stock springs and kyb shocks if I recall right.

If you look down from the top of the fendwer its 1 2/4 in.

Huh… do either of you know how much room you have on the inside if you moved the wheels in some before the tires would hit? Chris, I’m assuming that you are saying that on a hard lunch or turn they would scrap the outside fender lips?

These pics aren’t exactly encouraging, and the thing is that this wheel/tire shouldn’t be that much harder to fit then some thing like Hawaiian’s setup.

Thanks mark, I miss the dog and the car actualy....

Yes they would scrap the lip. I should have rolled the lip like I know to now. That was the 1st camaro I ever had. 406sbc w/ b&m mini blower,true duel exh. (the old one edelbroch use to make)3.73's,700r4, belive it or not I traded a fiero I had even up for it with a buddy of mine.

anyways.. Ya the pic's suck. like I said it was originally poliroid pic's. I just layed em on the table and took digital pic's for you.

The I really dont rem what the fornt size was.I want to say they were all the same because All 4 rims were the same 15x10. The front would rub the inner plastic on lock to lock. I had to take it out.

Wish I could rem more for ya but that was back when I was 1st getting into camaros and '95ish.

I uploaded 7.jpg and 8.jpg just 2 diff shots if that helps ya any. Prob not.

I know I dont have the width you're looking for, but maybe this pic can somehow help. This is 9.5" wide rear with 5.5" backspacing and 275/35/18 tire, no modification needed and no rubbing:

Anybody running a 10" wide rear wheel with the 285/40-17 and have lca relocation brackets? I'm wondering if they will interfere? I'm debating between keeping my 15x8 rears and et streets and also get some 17's for crusing or going for 16x8s all around with a rear 255/50 drag radial. Right now I have 15x8s all around plus a set of 15x8s with the et streets. I need a change but I want to do it right the first time (second time?).

Also, if the lca relocation brackets don't interfere then I have another question. My current 15x8s are 4.5bs, I was thinking going 5"bs with 16s out back or 6"bs with the 17x10s. I'm thinking a 10" wheel with a 5.5bs would look like my 15x8s with the 4.5bs right? I want to pull them in a little. I know the 6" bs needs a little coaxing to fit but really how much? Roll the lip, remove bump stops, hit the inner fender well, all the above? I did tons of searching but it's still somewhat unclear.

Chickenman35

17x10.5's all around in this picture with 315\35x17 CCW's. ( A friends wheels and tires ). No interference with LCA relocation brackets ( Spohn ). Karl Hunter runs 18"x10.5's CCW's with no problems. He's got room for 18" x11's on the rear fully tucked. LCA brackets as well.

Minor modifications with a BFH to rear inner fender well as others have done. Fronts take a lot more work......but since Karl did all of the legwork it's not fair for me to give away the details. Sorry.

ryn28

iTrader: (1)

Thanks for the info with the relocation brackets as I have Spohn ones also. What about the back space issue? From what I read 5.5 bs is no problem, even 5.75 should work from what I read so I'm guessing 6" bs only needs minor wheel well mods. If it means cutting out the bump stops though forget it b/c sometimes I will still run a drag tire so I want to keep those. As for the fronts I'd run something less wide that doesn't require any mods but with the same diameter. I figure a 255/45-17 front and a 285/40-17 rear would be perfect. I just need to get the bs issue down for the rears 100% before a spend the $$ on the wheels. Otherwise I'll just keep it simple and go with 255/50-16 with a drag radial.

Chickenman35

Bump stops remain in place.

nightrider87

what is the backspacing on the rims?

camaro05

iTrader: (1)

I would go with a 255/40/17 (First pic) The 255/45/17s in the seccond pic don't look as good imo. And they rub a little. I have sportlines also.

Kandied91z

iTrader: (7)

yeah with wheels sticking that far outside you shouldn't have to cut the bumpstops at all. even 6" with the right tire choice you should be fine. 6.75 is really close but you'll need to cut them i'd say 6.5 with the perfect tire you'd be ok so you shouldn't have any problems.

Chickenman35

Don't quite understand what you mean..." wheels sticking that far outside".

If you're referring to my car in my signature ( although it's hard to tell from that angle ), the wheels and tires are completely covered by the fenders and do not rub. Car in picture is doing about 90kph and is cornering hard.

ryn28

iTrader: (1)

Great guys, I'm getting the info I need.



I thought to use a 255/45 b/c the diameter is the same as the 285/40. It looks good to me in either pic and I'm not lowered so rubbing probably won't be a problem but what you said is something to think about.

Like Chickenman35 said, I don't know what you mean by the wheels sticking out that far? I thought a 10" wide wheel and a 6" bs should put the wheel/tire in the "right" place if I figured to run a 285/40-17.
