Well I figured this out but it's just for some reference.

I'm PRETTY sure the wheels on the red car are Boze Stingers.

What wheels and tires do you have on your car now?

Stock 16 inch Irocs, I've spent hours shining and buffing them, but they're the original rims, worn out from the last 23 years. Too many fine scratches.

That's just some random Camaro I saw on Google, I fell in love with the rims on it, been trying to figure out who makes them for a while now.

I don't have a clue, I was looking through wheel threads in the suspension and chassis forum for a while, before I got bored of it, and I didn't see any pictures of a rim similar to that.

Those were some awesome wheels. Could you repost the pics with the details of the rims?

i am a big fan or oem rims - they look good, were specifically designed for our cars, and they are already there, especially when you shine them up.
there are a lot of posts here showing how.
they are 8 inches wide and will handle a lot of rubber. they can handle more tire than the car can accomodate without some mods, some mild some big.
stick with the original ones.

I get so disgusted with uninformed enthusiasts trying to put 10" of tread width on an 8" wheel. Every major tire manufacturer will confirm what I'm about to share: You get better handling and response when the wheelwidth is slightly wider than the tread width. In fact, you're better off going down in tire width if you can't find wider wheels. Now I know that 245/50R16s on 16x8s are common, and some are impressive, but if you fit your car with 16x9" wheels which curently don't exist at any price, but you can try this with 245/45R17s on 8s then on 9s. Go ahead, try some 17x9s with 275/40s, then with the same tires but in a 245/45 size. You might think the 275s look better, and they Might help with braking, depending on your brakes, but they might also increase your braking distance. But when you quit going in a straight line, you'll be preferring the 245s. Much better recovery, much more predictable, mich quicker response. The reasons the factory went with narrow rims are cost, people's tendency to buy smaller, cheaper tires when money is tight, ride quality, and unsprung weight. But the weight can be addressed by going from cast to forged, which costs more, so the factory doesn't do it. Except on the original Vipers. You maybe could go 1/2" wider on the wheels, for the OE tire sizes, but that'd be about it.

Stephen

iTrader: (12)

I guess you are saying the factory was wrong on the 4th gens, putting 275/40s on the 17" x 9"s?

275s will not increase braking distance. How do you come to that conclusion? With the proper ratio, the overall diameter remains the same, but you get a wider footprint,. which means more contact with the pavement, which is how you slow down.

Yes, bigger better rotors & pads help, but after a point, all they'll do it lock the tires up & increase the stopping distance that way.

And no.....Wheel width wider than tread width does not increase handling & response. Manufacturers recommend a 2" range, like 8" - 10", 9" being the ideal width. No tire manufacturer will tell you to go with a wider wheel than the tread width.

And keep in mind.....Width that fits greatly depends on the sidewall. A 12" tire can fit & do great on a 8" wheel IF the sidewall is like a 75 series. Like Pro Street or Mud Terrain tires.

It all depends on the application.

Atilla the Fun

To answer this unresearched BS, ..

While narrow wheels with wide tires are not only possible but common, that doesn't make it ideal. If you care about performance, buy stuff closer to the ideal.

Stephen

iTrader: (12)

Again.....It depends on the application.

You can't compare tall tires to low profile ones. So what you stated "as the way IT IS", is not entirely accurate.

On a Pro Street or Mud Terrain tire, you are going to want the wheel widths smaller than the tread widths. That is the way the tires were designed to operate.

And I notice you chose to ignore the part about 4th gens & 275s on 9" wheels....Call GM & tell them YOU know more than THEM. They'll thank you for the help.....

Atilla the Fun

First, to the OP, I apologize for Stephen turning my response to my friend Tony into ahijacking of your thread. I posted here instead of in a PM so Tony would be sure of what I was responding to.
To Stephen, for the third time now, GM likes to use narrow wheels for reasons of cost, ride quality, et cetera. GM was not interested in best possible performance, or they would have used 9.5" wheels like they did on the '88-up vettes that also used this 275/40 size. Because 9.5s do fit. GM doesn't care if we know it was compromised, they never claimed it wasn't compromised. Compromise is their business. Lastly, off roadiong isn't performance. Not as third gen enthusiasts define it. If you're off road, you may want a wider tire to protect your rim. L:astly, my '82 Camaro is my canyon carver, so for it I chose to run 255/40s on 17x9.5s, looks be hanged. My '84 Trans Am is my comfy car, so for it I chose 275/40-18s on 18x10s, to look good and fill the wheelwells, while still having the wheel as wide as the tread. It suffers from more unsprung weight compared to my camaro, a higher center of gravity, poorer acceleration and braking, but it's a T-top that plays a different role for me. The 255/40-17s do look too short on the camaro, the fenders need to be modified to reduce the tire-to-fender gap, but they give better acceleration, braking, handling, response, recovery, center of gravity, and unsprung weight. That's performance.

No hijacking going on.....Just needed to clear up your bad information, that you were spreading.

Your apology to him should be for the misinformation &, not about me.

Atilla the Fun

Everything I post is independently verifiable.

RED_DRAGON_85

what you are trying to say is that a wider tire will have more sidewall deflection for a given wheel width when you are initiating a turn.
the sidewall has to go from pointing away from the turn, to being in tension before any serious turning action can occur...

HOWEVER

some tires (in fact most performance tires) are designed with this in mind and have sidewalls that will still give great turn in performance WITHOUT stretching the tire on to a wide wheel.



having a wider wheel than tire ensures that ALL of the tread width will be flat on the ground, wheras a wider tire will tend to balloon out, and some of the tread will be "wasted"

HOWEVER

some tires (most performance tires that is) also take this into account, and have very stiff and thick shoulders so that they are put to good use on turn in.


adjusting your tire pressure can also help here
if you want a more assured feeling ride, run a smaller aspect ratio and skinnier tire with a higher pressure

your ultimate grip will be less (less rubber on the road) but the FEELING will be better
again, you have less tire on the road, so you will have less ultimate grip, but the car will FEEL crisp.
this is similar to running a slight toe OUT on the front. gives a more twitchy feel....


for the most grip, run a wide tire... run the widest tire you can.
also, run it at the lowest pressure that you can get the most grip from. this does not mean 10 psi... this means enough pressure to keep the sidewall from completely deforming, and the tread from not contacting in the middle, but not so much that the sidewalls are completely stiff.
its a trial and error deal.

your camber settings also come in to play here.
more camber is good for ultimate cornering grip, but street cars tend to run almost zero camber because they are going straight 80% of the time, so negative camber only wears the inner shoulder more than it should.
thats where caster comes from
the idea is to run the most possible caster and least camber and get the most grip in the turns while not wearing the tires on the straights

atilla, your intent is good, but you need some more info to be an expert
i am in no means an expert, but i do know a thing or two.

Stephen

iTrader: (12)

If GM was about saving $ on every aspect, they woulda used a smaller wheel. Smaller would be marginally cheaper to build, per wheel. But spread a few dollars out over a million wheels (4 per car, plus inventory replacement builds).

Your "information" doesn't even agrees with itself.

Atilla the Fun

Red Dragon, is it? Just because I'm not good at expressing what I've learned doesn't mean I don't know my stuff. For about 25 years I've been obsessed with tires, and I've learned all there is for someone who isn't working for the big tire companies as an engineer. Stephen is just mad that my research disagrees with his popular opinion and personal convictions, but I'm done arguing with him. I fully realized all of the points you made, but true as they are, they don't contradict what I've posted. I stick to the facts, even though I share some of my experiences, and I make sure to make it clear which is which. GM does care about a dollar a wheel in materials, times a million wheels, is a million dollars. My facts do not contradict themselves, much as Stephen is trying to twist it that way. Lastly, as I said, I posted that as a few words to my good friend Tony, not to get into a pissing contest with Stephen or you, and I don't get into them if I can't win them. If you disagree with anything I've typed, you're free to say so, but if you wish to attack, attack my poor presentation all you want, but you really can't fairly attack my research without first learning the full extent of it.

RED_DRAGON_85

all i am saying is that given two otherwise equal tires, mounted on identical rims, the wider one will have more grip.
its a physical fact
there is no way around it no matter what

now...
FEEL is different.
a smaller sidewall and thinner tread (say 7.5" tread) on a 8" wheel will FEEL like its on rails
newer corvettes come with 275 rear tires on a 10" wheel (i believe)
that is much smaller than you can run
a 10" wheel can easily and safely run 335 tires if you want
its the fact that the corvette is SUPPOSED TO HANDLE LIKE ITS ON RAILS
GM knows that 90% of the owners will never get to drive the car on a track where ultimate grip matters... and even less will be good enough drivers to be able to make the most of the grip the corvette offers
so how do they make the car FEEL like it has infinite grip without spending an arm and a leg?
give it super wide wheels for the tires it has.
that way there is no sidewall deflection and instant response.


now look at the camaro
it has 8" wheels, but the same 275 tires
the camaro handles just about as well as the corvette, but takes a bit more finesse to get the same lines.
the actual grip is the same, but its just a bit harder to use because of the sidewalls deforming on turn in.

given an experienced or professional driver though, the issue becomes less about sidewall deflection and more about ultimate grip, because they know how the car will react and can easily account for it.
for them, they want the widest possible tire they are allowed.


its just that inexperienced non-professional drivers are not able to fully utilize the grip, so GM made it FEEL grippier by giving the corvette wider wheels

1988-305-tbi

most all newer performance cars have some what stretched tires my buddy has 2007 350z he hated how the 225 front tires 8" wheel and 235 rear tires were stretched on the rims. he put 245 on the when he got his first set of tires, and 255 on the rear, it looks better but handling not so good, you feel the sidwalls roll and get a delayed steering feel,

the camaro got 275/40 17 tires on a 9" rim and the corvette got the same size tire but a 9.5" wheel, which car did gm intend to handle better.?????????

No.....I'm just tired of people (like you) passing on bad information as "gospel" when it isn't even close to TRUTH. Talk to the autocross, 4x4 & drag racing crowds & they all will back up with what I said.

So you are agreeing with me, yet you think GM wouldn't care about a million dollars? I guess if people like Obama were bailing me out to, I wouldn't care either.

You can't win, because your information is WRONG.

I have been disagreeing with you, yet you wanna "run away"? I guess you don't wanna "argue" with me, since you've realized every "fact" you posted has been shot down.

1988-305-tbi

just having a wider wheel on the same tire will actually increase the footprint by holding the tread flat, on a wider wheel it will ballon, alot of BAJA/off road Trucks will due this because with a flat footprint the truck will only touch the surface of the sand, but with ballon tires the tapper helps them sink in and allows more bite beacuse they are now in the sand and not just skipping accross the top

I H8 WWD

I don't see any wrong information here, the only misinformed part of this thread are the two arguing. Both of you are right, and hate to say but right by application. I will choose a tire that is ballooned a little for a more comfy ride, but the performance would come from equally matched tires to rim width obviously. So calm down because nobody is talking BS, your just each expressing a different application in the way you choose your tires.

Now thank you for all this great information, because honestly, WHO THE HELL thought tires could get so deep in conversation.

-Take care

We've barely scratched the surface on ONE aspect, wheel vs tire width.

Then there are compounds....tread design....aspect ratios....tire weight & wheel weight..........

RED_DRAGON_85

lol....
i cant remember if this board forbids posting links to other boards or not (some do)
but if you look on some of the g-machine and pro touring websites, they have entire subforums JUST for tire discussions.
then there are the forums for advanced suspension theory... ect...
trust me... there is a lot to know.
the more you dig in, the more you realize you dont know.
kinda like digging a hole.
the farther in you go, the bigger the pile of dirt. (the dirt being stuff you need to find out)

Oh man, you guys got serious about this thread, I'll repost the picture and names of the wheels.

Shadow Z

iTrader: (2)

I want some opinions on this wheel, and instead of creating another thread, this one is perfect.

So I've been looking around for some other decent 5 spoke wheels, and I've pretty much found the perfect wheel for these cars. www.lakeshorewheelandtire.com has a set of C6 Replica wheels, 18x8.5 and 18x10.5 rears, but get this, only $899, that's a super good deal in my opinion.

Let me know what you guys think about it, it fits these cars perfectly in my opinion, simple, straight, thinner style 5 spoke wheel, flows with the body perfectly.






By the way if you check out this thread, kubus_stroinski, I really hope you don't mind I used your car as an example, it's just that it's probably the sickest car on TGO.

Thebighouse111

I too have a 86' Iroc-Z and i was searching for new wheels as well. Will the corvette replica wheels fit without any mods? I thought that because of backspacing or something you couldnt put 8.5 on. I would love to get a pair of wheels like this so please let me know. thanks

Stephen

iTrader: (12)

To run Corvette or 4th gen wheels, you'll need adapters for them to fit.

Thebighouse111

Do the adapters effect performance, braking, handling or anything that would hurt the car?
