When you buy a car the first few modifications that come to mind involve wheels.

They are a very personal decision.

Then if you are in the category of a car owner who wants that perfect car, changing wheels are definitely a priority but for another possible different reason:

Performance.

But what is unsprung weight? most who purchase aftermarket wheels either go on the knowledge that if they are aftermarket, they must be better. It would logically make my car faster! And make it look good too! But the reality is although aftermarket wheels do reduce the unsprung weight of the vehicle, the level at which it does it varies.

And believe it or not, sometimes they actually increase the unsprung weight.

Meaning the aftermarket wheels that you buy, can, actually be heavier than your factory stock steel wheels.

Kinja'd!!! Kinja'd!!!

A stock 15" steel wheel weighs around 20lbs , or 9.07kgs .

And my previous ROH brand Alloy wheel, in a bigger 16" weighed a staggering 21.4 lbs, or 9.7 kgs for an alloy 5 spoke wheel.

Aftermarket wheels do affect the feel when driving, but to be honest most car owners buy wheels for their looks. I was clueless about the weigh as the general logic and principle for Aftermarket Wheels are as follow:


Factory stock Steel Wheels (Heaviest)

Aftermarket Alloy Wheels (Lighter)

Carbon Fibre Wheels (Lightest)

Large Diameter Wheels (Heaviest)

Small Diameter Wheels (Lightest)

Kinja'd!!!

But the reality is the design of the wheel affects its weight, and the smaller the wheel the less unsprung weight you would have. This is due to Air in the tires always being the lightest thing you can have around your wheel.

This is the reason why most Formula 1 cars have massive tires- they are simply lighter.

Kinja'd!!!

Well I have since moved on to 16" inch Starcorp Lite5 wheels which weighs only 13.5 lbs, which is 6.1kgs.

6.1kgs!!!! The advertised weight was 6 kgs on their site, and weighing it on my scales it was pretty close to the advertised weight.

However if you are unsure how much your wheel weighs, and are worried you made a bad purchase, don't worry. Aftermarket wheels have better ventilation which is a plus for your brake system and causes better airflow for cooling the system. They also improve on vehicle handling feel usually. And resale values for Wheels are generally high.

Now I only have to get really light tires and brake disc.

And the feel of a light wheel? Phenomenal. Imagine moving from non power steering to power steering. Now imagine from power steering to Super Power Power Steering. Acceleration, feel, ease of turn is just amazing.

So yeah, for those tl;dr's, this:

My previous alloy aftermarket wheel: 21.4 lbs (16")

Stock Steel wheels: 20lbs on average (15")

Air is the lightest bit for your wheels.

Current Alloy wheel, 13.5lbs (16")

Post your experience on purchasing wheels, the misconceptions you faced, just generally why you chose the wheels you did!

There's a reason they're everywhere.

I want a set in the same size as my OEMs (17s). I'd love to go an inch higher for looks, but I'd be spending more and they'd be slightly heavier. I'm not so sure it'd be worth it. A little bit more sidewall couldn't hurt, I guess.

EDIT:

Though, even at 18s they're still around 4 or 5 pounds lighter. The stock wheels on my WRX aren't that bad. 22 pounds.

You're right. If I ever buy aftermarket wheels, it'll be hard to beat my current 12-pounders. That said, the wheels I want are just about the same weight, give or take a pound (depending on width—haven't decided on the best partner for a 205/50/15).

It's amazing not only how light Miata wheels are but also how available they are. You don't have to look hard to find a set of four daisies for 100 bucks, and the BBS's wash up on forums/craigslist pretty regularly too. Only real reason to go aftermarket is if you want more width.

Wow 12 pounds!! that is light!! Can you please post a pic of your car and tires?

I am currently running 215 /60 /16. Within my budget so they are not expensive lightweight tires, they are Blacklion tires.

I was initially going to get the Rota slipstreams, but glad I didn't. It is actually heavier than my Starcorps. My starcorps are a shadow chrome which is nice. Never knew I could get performance and looks on my budget lol ($550)

The reason why most Formula 1 cars have massive tires is because the rules state they have to have 13" rims with massive sidewall.

Given the chance they'd go for less sidewall to reduce tyre flex, but as it would change the suspension dynamics so radically it would require a whole redesign of all the car.

I am no expert on wheels: I know a lot about them such as offset, stud patterns, etc. but still a lot I don't know or concepts I am unclear of.

I know a lot people say any tire can fit on any wheels. But the reason you don't is because you risk the tire popping off the bead seat correct? That is why you can't just get wider tires, but you have to get wider rims.

But to what extent? The rigidity of the tire is a factor too right?

But lets say is 8" wide tires too wide for a 7" wide rim?


Kinja'd!!! D > DoubleDragon
04/29/2014 at 01:30

I'm not hyper-educated in this field either but basically if your rim is too wide for the tire, you'll get that tire-stretching effect and if you go too narrow your tires will balloon. There is certainly some give in either direction but you'll reach a point where it's dumb/unsafe before long. From what I gather, it's best to have a straight or slightly stretched sidewall for performance driving.

Like I have 185's now. I could definitely go to 195's on the same wheels but wouldn't touch 205's.

I purchased new wheels for three reasons. I wanted to drop weight, stock wheels for my car weigh in at 28 lbs at 18". I wanted better traction, so I went wider. I also wanted the option of fitting massive brakes in tbe future if I wanted, since I didnt buy the brembo option at the factory (a mistake, I know)

Yep! I think they'd look great in black with my Satin White Pearl WRX. I just have to figure out the size wheel/tire I want. I could go the practical route, which is to just go with the STI's 245/40R18. It's a safe size. DD-able and zero rubbing.

What is the reason for that? Is it because of sponsorship funding? (bridgestone)?

I recalled a lot of testing done by journalist, car enthusiasts that after a certain point the larger sized wheels lowered lap times. I know its not the best reference but the Australian V8's use smaller wheels and larger tires too. So the 13" rim size currently at the Formula 1 level is not the optimum size you say>

can you please enlighten with a weblink or two so I can read up and learn more about the optimum size vs performance on Formula 1 tires..

I love playing with wheel setups. It changes the handling dramatically, especially with tire pressures. Manufacturers always recommend comfort at low psi's (my car is a 90's car) but at higher psi's wheel width and size have an even bigger effect.

I ran wider tires up front and smaller out back, trying to have more oversteering similiar to gymkhana type setups. I am driving a FWD but the effect was really to my driving style, 215 vs 195. Do you know much about staggering tire sizes and handling?

Haha, 'daisy' wheels are what those wheels are known as in the community. They look like flowers when they have the center caps on—which I don't. When the center caps are off, they look a little like Panasports or Watanabes, those might be the wheels you're thinking of.

I'm in love with the way this car drives! Even with its stock suspension, it corners exceptionally well. I think the thing I like best about the NA Miata is that one moment, you can be putting around town getting 30 mpg and parking with ease and the next moment, you can absolutely annihilate corners. It has a great learning curve; easy to drive well but challenging to master. The NA is kind of a cliche in the auto world but there are sound reasons for that.

I'm afraid I know nothing about staggering sizes.. It seems like an understeer/oversteer bias could be encouraged though. I feel like sway bar setup might be the easiest way to do this, as well as alignment setup.

Width also has an effect on the wheel weight, although admittedly much less of an effect than diameter. Just throwing that out there, and also to help justify my purchase of same-as-stock width wheels for my car. I recently got much lighter wheels at under 19.5lb per corner. This is not on a Miata, however, this is on a GTO with 18x8 wheels. Stock (if I remember correctly) is about 25lb per wheel. I could have gone with 17" but they wouldn't fit over the brakes I have yet to install. Aw shucks, there comes more of the enemy (unsprung weight)!

That sounds awesome... Nothing beats power delivery in the corners. Its the reason I prefer japanese cars to muscle ones. Your miata is awesome, red is a winning color too ;) Is the stock suspension stiff? I know the Elise has similiar dimensions and I know even with heavy engine mods the stock suspension is more than capable. I think its the dimensions of the car like your Miata and the Elise that makes the difference.

I've never really been a fan of bolt on turbo's, but I do love the Evo. But I love my NA engine, its a 2.6Liter inline 4 and the power delivery is early in the range, with power-band delivery at 2,500 rpms and another at 3,500rpms. It satisfying when you hit that powerband, either at 2.5 or 3.5 and the car just digs in even more around the corner, and the engine sound along with the tire slightly squealing at the limit. The crazy awesome thing is after my new wheels, going round the corners is even more fun, with the a new tire squeal I never heard before. Like a very slight squeal-squeal-squeal while pushing it at the limit in the corner like a baby Turbo flutter sound.

I think people love turbos also largely due to the sound they deliver ;)

Also, have you put in an extractor kit and pipe yet? the extra flow can unleash the sound of your miata, when the airbox sucks in more air and the noise when you let off the gas pedal and the engine revs down sounds way cooler than a turbo!!

The car is stock except for brake pads & fluid and the driver seat. I have no complaints about the stiffness of the stock suspension. I don't track/auto-x the car but I go pretty hard on mountain roads and it does its duty. My only problem with it is how high it looks from the factory but that's trivial. All in all it's great for a stock suspension, definitely enough to hold me over for a looong while.

Not long from now, I'd like to get aftermarket sway bars as well as a custom alignment. These are very cheap upgrades and have a significant influence on the handling characteristics.

Ouch, front + rear aftermarket sways will put you down $200 for the NA. Everything seems to cheaper for these cars.. Read up on the forums if sways are worth it, that's the best way to decide

Are you going oversteer or under?

With custom alignments are you talking about playing with camber as well?

I agree with the look, I would love a lowered car look but the problem is the roads around here.

Maybe we should look into bodykits for that lowered look while maintaining some form of suspension.

I don't have any links, but the tires are a crucial part of the suspension in F1. Part of it is the rules mandating the tires to be a certain size, and part of it is that the engineers know how to work with those tires. The amount of engineering that goes into the F1 tires is staggering to say the least.

There are some performance tires that are heavier than others out there just as some tires tend to be narrow for their section width and some that tend to run wide for their section width. Sidewall flex will play a huge role in how well the car can corner, grip, and absorb bumps. Many people forget that tires are the first component in your vehicles suspension.

The NA is pretty damn neutral right out of the box. I'd opt for a setup that remains neutral, perhaps with a tiny bit more oversteer. Mostly, I'd just want it to be able to take corners a little faster than now.

Camber is part of the plan. People have come to conclusions about the the best-performing alignments for NA's running stock suspension—it involves maxing out the front camber. Best part is: this setup isn't reported to wear your tires any faster than normal and if you drive hard like I do, it in fact wears your tires less :)

The only problems I have with small wheels:

While they do save unsprung weight you can't:
Clear bigger brakes
Fit wider tires
Fit thinner sidewall tires (without plus sizing or downsizing your tires)

It's hard to find an affordable, lightweight, good looking 18x9.5 wheel.

Lol misunderstanding, I though you meant NA as in Naturally Aspirated as opposed to Turbo. Hence my turbo rant. Not a miata expert but am learning now!!

Im reading up on it on wiki. a curb weight of 940kg! pretty cool. 0-6o of 8.1secs.

When you max out the camber, you are talking about negative camber, toe out? Would tyre places just do this, or do you have to know the shop pretty well? like, due to laws. When you go around the corner the idea is that the camber allows more grip on the outside tire or inside tire?

as far as I can tell there's no legitimate reason other than a carry over from the old days and the cost of redesigning the cars.. I think it was the early 80's when they banned the cars from having more than 4 wheels (like the P34) they set the limit on what diameter they could be also.. but I can't find any citations. Can't find anything technical and F1 specific as no one has tested larger rims on an F1 car.

As Yokohama put it - "A tire with a lower aspect ratio responds to lateral force more effectively than a tire with a higher aspect ratio. The aspect ratio affects steering stability. Generally, the shorter the sidewall, or the lower the aspect ratio, the less time it takes to transmit the steering input from the wheel to the tread. The result is quicker steering response. Aspect ratio also affects the tread contact patch. As a rule, a low profile tire produces a wider tread contact patch. This wider tread contact patch creates a stiffer footprint that reduces distortion and provides improved cornering traction. Aspect ratio also impacts ride. A low profile tire usually has a stiffer ride than the standard aspect ratio of 75 or more."


I definitely agree that reducing sidewall too much has a negative effect, you have to run a higher pressure and you end up with less contact surface on the road under load. So there would be a balance that needed to be maintained.

Larger rims also means you can fit larger brakes, though F1 cars are already at the limit of their braking grip so I'm not sure if they'd see much of a benefit.

Here's a couple pages on Miata alignment if you're curious. Yes, lots of negative camber up front. The idea of negative camber is that when you corner, the contact patch of the tires on the outside of the corner increases, giving more grip.

Nice Mitsu!

"When you buy a car the first few modifications that come to mind involve wheels."

Speak for yourself. Some of us live in countries where that's the last thing you'd change, because the benefits are minimal and it pushes your insurance premiums through the roof. Plus, I generally prefer the stock wheels.

Saying that, I have thought about picking up a set of these for the E30:

Kinja'd!!!

They're so unloved that they go for next to no money on Ebay, and being stock fittings they wouldn't affect my insurance.

"And believe it or not, sometimes they actually increase the unsprung weight."

Oh, I know. I've encountered a whole load of resistance to that idea round here, though, so it's good you've actually put some on a set of scales.

One thing to add is that not all steelies are created equal. There are lighter and heavier ones out there. A good set of well-made steelies is hard to find, but may be quite a lot less than normal ones.

"This is the reason why most Formula 1 cars have massive tires- they are simply lighter."

I'm not sure about that. I've been trying to get a definitive answer about the size of F1 tyres for a while, and there seem to be a number of contributing factors. The main one, apparently, is simply to give the tyre (and air inside) enough heat capacity to stay up to temperature fairly consistently. It's also perhaps lighter than some other configuration, as well as providing the majority of a car's suspension travel. (Don't forget that suspension is also unsprung weight, and that may well be something the air in the tyres is lighter than.)

thanks for this post, I was not aware of any of this as I have only been into cars in the past year. Plus I love informative reads such as this.

So after reading it, I have a question (if you don't mind). from what I gathered, and that the Internet told me; The unsprung weight is the weight of the car suspension, wheel, and other components directly connected them (I hope I'm on the right track). So my question is this, why would someone knowingly after their unsprung weight? Are there certain situations where it's best to make the weight heavier or lighter?

You're right about this. The thing that took me by surprise is the weight of Minilite alloys for classics. They're actually really rather heavy as alloys go. Strong, but heavy. Apparently the genuine Minilites were racing magnesium wheels back in the day, very light very strong but terrible finish. They were for speed, not looks.

Current ones are aluminium alloy. Just as strong, better finish but heavier.

Oh, another thing to consider is the weight of the tyres you're putting on the wheels. If you start with a 185 section tyre and move to a 205 with your new wheels, that's going to increase weight significantly. If you're lucky you'll end up with roughly the same weight as your stock wheels, but with a wider contact patch.

I've done a lot of research for wheels that'll fit my Miata. I'm running on the factory 5-spoke 16x6.5" and they weigh a hefty 15.5 pounds (probably more due to all the paint on them). I'm looking at downsizing to 15x6.5 for autocross purposes (no good tires for 16" plus the best R1R compound in 15" only) and I'm looking at getting Konig Helium that weigh only 13.2 pounds. NB Miatas came with 15x6" wheels that weigh 13.1 pounds but I need that 0.5 inch to help stretch a 195 tire over it. Every other 15" aftermarket wheel wheels 15 pounds or more.

Good post. This is something we were discussing in a few posts about Cragar soft 8's.

One very important thing to remember is that the wheels should be DOT approved (for the USA) and designated for street use if that is their purpose. You can buy expensive superlight wheels only to have them disintegrate when you hit your first pothole... and hopefully that's all you will hit.

That's not even getting in to forgings vs. castings.

Anyway, I went from 15x7 GM ralleys @ 24 lbs each to 15x8 Weld Racelites at 12lbs each. Yes it was noticeable.

Hi there! :)

No problems, glad to answer any questions to the extent of my knowledge :) Others with more experience and more extensive knowledge would probably correct me and hopefully we can all help each other and provide you with the best knowledge.

To be honest, in every field the terminology is the main thing we are unfamiliar with. Terminology is just a label to put a word on something we describe; My field is in molecular biology so automotive is not my chosen field.

I think an analogy, or a scale easier to imagine to make it clear for you, is that the wheels, is the spinning component that "motives" your car forward . Now if you ever had a Remote Control car you would notice that when you accelerate the wheels spin.

Kinja'd!!!

Now picture filling the Rubber Tires in the picture above with concrete. Or with the densest atomic particles, something you are familiar with such as lead, or maybe osmium which is an element like lead but weighs 22.59 grams per cm3. If you fill the Rubber Tires above with stuff heavy enough the wheel at one point will not be able to spin. The motor would not be powerful enough or have enough torque to even start spinning the wheel.

Therefore:

Heavier=More difficult for "motive", pushing the car forward.

So in your question you mentioned the components attached to the wheel, suspension, etc, is this:

Any moving parts, attached to the wheel, generates a weight. So your b rake discs, which are attached to your wheel, which spins when the wheel spins, if heavy enough will slow your wheel and decrease "motive" force . Like the cement in the tires. In fact, the tires itself weigh something and the heavier the "slower" or "harder" (actually more force against moving due to weight) it is for the wheel to start spinning.

In your question to suspension, think of the imperfections on the road. when you go over a hole, a lighter wheel is actually easier to push down by the suspension into the hole, so when you accelerate the wheel which has now contact with the surface in the hole can provide "motive" force forward with traction.

Quote wikipedia:

" a lighter wheel which readily moves in response to road bumps will have more grip and more constant grip when tracking over an imperfect road. For this reason, lighter wheels are sought especially for high-performance applications. In contrast, a heavier wheel which moves less will not absorb as much vibration; the irregularities of the road surface will transfer to the cabin through the geometry of the suspension and hence ride quality and road noise are deteriorated "

And hopefully I am helping so far, and you can understand me so far. I always believe learning has nothing to do with the ability of the pupil to understand, rather the ability of the teacher to impart knowledge in a way the listener understands.

Not that I am an actual teacher and you are actually my pupil lol lol.

ok so the last part- application of lighter wheels and heavier wheels.

Lighter wheels are better for acceleration, traction, and easier to "motive" push forward a car. As you recall filling the wheel with dense and heavy cement would make it less "easier" to spin the wheel; vice versa the opposite by making it lighter would make it easier to spin the wheel generating "motive" force.

I am not sure how a heavier wheel would come into play in terms of application. I am not a engineer/physicist and do not have experience with the laws of physics as in studying them, (although I did University level physics) I always thought the heavier an object is at speed, then the more momentum it carries and helps keep the speed.

Heavier wheels tend to be stronger, but as in my case when I bought the wheels remember there are a lot of variables. Structural (wheel shape and design) molecular (strength and toughness is different, toughness is the ability to cope with forces after the breaking point, such as by adding carbon to the steel). Stronger wheels are used in applications where forces act on the wheel (4WD / offroad)

Hope I helped. also remember that due to centrifugal? centripetal? forces, which is a force due to spinning, the weight of the wheel has an even higher effect at higher speeds. something like 100 grams becomes 500 grams or something like that (depending on the speed of course). Don't quote me on the last bit!!

That is slick!!! Nice car! That is the best color for that car.

Brembo's for 2k??? that is expensive. I think its good you didn't get it, I am sure you can get Brembo's for cheaper if you shopped around.

Those are valid points!! I should post them up.

I have smaller 15 X 8.5 inch wheels though. That might not be wide enough for you as you are at 9.5"!!!!

Had to share this with you guys.

The first mod to it had to be wheels. The standard issue OZ SuperTurismos were decent enough quality but they just weren't doing justice to the car's aggressive lines

It's a good read and funny she had to have the wheels changed.

Can't believe she crashed it afterwards!!!

Thanks man, I'm pretty proud of the car so far. I've found a set of SVT brembo for just a bit over a grand, which I may bite on after I do some suspension work.

Thank you, you cleared up a bit, its still slightly muddy in my head, but I have the basic idea so I can always build upon that :) . And I'm a entry-level programmer, with a BA in Game and Simulation Production; so its not my field either. But I enjoy knowing a bit about everything, so again, thank you. It was an excellent answer, better than what I expected. I'll re-read it later today to after I let the first batch of information "sink in".

Years late, but for others who may be interested...

The OP’s Starcorp Lite 5s are available in 15x6.5" and weigh 12lbs. I have a set on my CRX ;)

You may have to find a used set, as they’re an old design. I bought mine in 2004.
