- I Made A See Thru Wheel Balancer to test and show how and why the Wheel Balancers work and I also tested balance beads to show if and how they work and filmed it with the High-speed camera to show in slow motion visually what's happening inside the wheel Balancer with the balance beads.
Based on the CentraMatic Wheel balancer design and used with counteract balance beads.

Centrifugal force is greater the farther you are from the axis - F=mr(ω^2), m for mass, r for distance and ω for angular velocity.
Unbalanced wheel having it's center of mass slightly of the axis shouldn't really matter, because it's not spinning free - it's fixed to the axis. That's why you get vibrations with such wheel, as the heavier side tries to fly off stronger than the lighter side. If they were equal the forces would be equal and nothing would tug on the axis.
Now, considering both of the above, the heavier side will tug on the axis and this end of the wheel will travel on a bit larger circle than the opposite, lighter side. This creates greater centrifugal force on this side and balls are pulled stronger to this side, not to the opposite side. And to be honest, in the test with added fixed weight, I can't say there's more balls on the lighter side.
Many, MANY engineering problems wouldn't exist if loose elements inside an enclosure rotating around a fixed axis would by definition place themselves so that the entire thing is balanced. This almost never happens and that's why modern washing machines have algorithms to try and balance the laundry inside before spinning.
Thanks for spelling it out and thanks Warped Perception for pinning it!
It might work somewhat with beads inside the tire because heavier side may hit the road harder redistributing the beads a tad more.
Were it to work well, it would be the industry standard (I remember reading about putting glycerin in tires back when tubes were a thing).
I wonder if there's any damage to the rims after some prolonged use.
I mean, beads are made out of steel and some rims are made out of aluminium.
sorry if this doesn't make sense
Only warped perception is crazy enough to test his balance beads by doing a burnout 🤣
An excuse to do a burnout 😂
@@volvo09 no excuse needed tbh.
In his garage!
@@cloudpandarism2627 agree
burnouts arent crazy, poss get out more
That wasn't too deep at all, it was just right. I understand it fully now. Great demonstration.
So glad you are posting again. I love your content!
Thanks... It's been a real struggle, I went full time TH-cam November 2019, then the pandemic hit, then I had a brain injury all while being a single parent, I'm just now starting up... Crazy the things life throws at you.
@@WarpedPerception Glad you are back, and this video is such a great subject. Thank you for doing all the work to get this testing set up.
@@WarpedPerceptionhang in there buddy, you're truly one of the gems on this platform
@@chiefdenis thanks! Much appreciated
Holy crap, I think you explained it perfectly because I totally understand why and how it works now.
I was a little confused after your first video this one cleared it up seeing it and hearing it.
Thank you for taking the time to film, edit, and post this video.
I see I must just be needing balance beads in my clothes washer now.
That. That. Might work....
@@TheJttv for real I spent $900 on a new top loading washer with agitator and the dang thing thumps around like a bear fighting it’s way out of a locked car if you put two pairs of jeans in it. Really annoying. It’s been leveled and all 4 feet are under even pressure on the floor. Just don’t make stuff like the used to.
Damn thats a decent idea to patent. A outer 'donut' on the outside of the drum full of beads to balance out a uneven washing load to reduce vibration.
some washing machines have balance beads inside or use water to self balance.
that slow mo was crazy!
I use beads in my Vespa, 12". Longer life out of the tire and no funky tread wear patterns.
I have my own equipment and still use beads. They maintain balance over the life of the tire without additional labor.
This is especially true if you have alignment issues or dual wheels that naturally can not wear evenly.
Always a good day when Warped Perception uploads. Keep up the awesome content!! 🏁
Thank you, I'm trying
the extra noise + sandblasting the inside of my rim and tire... not something I'd ever want in my own tire. But It's amazing to see it actually work, and the part about center of gravity / center of mass finally makes it make sense.
I wonder what a wheel would look like filled with non-newtonian fluid?
Continuity of a series. Love it 🏁 always appreciate your thoughts to help us understand better!
Thank You! I never understood how these beads worked either. I had a set of 42” Super Swampers on a Ford truck and used these beads. I never noticed any tire vibration while on the freeway. They seemed to do their job since I never noticed vibration from the tires and Super Swampers were notoriously out of balance in those bigger sizes
I think thats one of the best applications
Awesome vid! I remember seeing a similar tube/beads device in the mid 70s at a car show in Cleveland with my dad, and always wanted to know if and how they worked - you have solved a 45-year quest!
Genius! I have had a hard time visualizing balance beads working myself but now that I have seen your video I not only understand it but the old time wheel balancers where you put your hands on the spinning bearing until it smoothed out make a little more sense too. ( I probably butchered the description of the balancer. I used it twice back in 1978 and it was ancient back then.) I would be concerned these beads would turn to powder after time and be useless.
Excellent!!! Thank you for testing this and the explanation of how they work. Love your tenacity and creativity!!!
Good explanation and the visual really adds to the answer. Thanks Matt!
Awesome to see how those actually work. Great video!
i didnt even know these existed, great content with this one, ill be definitely using these in my winter beater with scrap tires
That's pretty much how CD/DVD drives work. There's a bunch of small ball bearings in a track, once the CD gets up to speed the ball bearings compensate any imbalances in the disc
That's really cool to see them in action!
Good job doing the science
very interesting, cheers!
Man this guy took the game to the next level!!!!
Crazy ? Heart warming and thought provoking
I use counter act beads in our motorhome tires and trailer tires... total game changer! There's no going back. Not only did they smooth out our motorhome, it also drastically reduced the tire temperatures. I don't think they work in small passenger tires or front wheel drive vehicles if I remember correctly from what the folks at counteract told me.
This guy is a genius!
Awesome Bro! This is exactly what i want to know!
Nice job breaking down the science behind it
Scotty Kilmer had me to check out your channel. I finally have an understanding of how those balances needs work.
A couple people told me that already, how did you find me from Scotty kilmer?
@@WarpedPerception it was the jet engines on your tesla - last night he mentioned rob on ageing wheels because he's doing an electric conversion. i'm terminally online so naturally i'm sub'd to all three channels but yours is my favorite even if i watch scotty the most.
I can vouch for the effectiveness of the centramatic wheel balancers on my truck. I got them installed on all six wheel ends. the truck rides much smoother like it took the harshness out of the vibrations of the tires. They're not 100% effective if your tire is out of round that's a lot of mass that it has to compensate for that the centramatics don't have in them They do sound like an air leak when riding next to a building below 15mph. Excellent demonstration doing burnouts inside the shop! That E55 sounds awesome
Loving the car choice👌
As a person who has balance beads in my 285/75r16 off road tires I can tell you YES they work because my tire guy could balance them due the tires and my rims are probably as old as the truck (which is a 95 F250 4x4)
Fundamentally they have to work because as the imbalance would cause a centrifugal throw. The beads would naturally lean out and occupy where the need arose
Centrifugal throw, That's probably the term I should have used That kind of sums it up.
@@WarpedPerception
Don't get me wrong Brother. I know how to stay in my lane.
It's just that we had to learn about something like that during Electronic Vibration Annalasys. The term must have been stuck in my head or something. 😄
A worthy video
Love your videos
Thanks
"looks like with that weight there a lot of the beeds have now moved to the opposite side of the rim"
No it doesn't look that way 🤣
I know they work since semis all use them, no wheel weights ever on a big rig ive seen, but now i get HOW they work. Much obliged
When I was driving over the road back then they kind of were first coming out and guys were using them, so I decided to try the bolt on ones I can tell you that I did not think that they worked that well but those were the front tires, IF you have a good balance guy, I think they work better than the beads . .. but the beats definitely helped as opposed to not having the beads on there at all and not balanced, plus you never going to throw weight
youre a very smart guy, i like the way you think about things, and you do an even better job explaining your reasonings
0:20 1st view😎👌
lmao "is it a LIIIEEEEE???" Dont forget to balance JetKart.
when will you make some more mini engine videos?
Soon... Just been recovering from an injury back in September, just getting back to it.
@@WarpedPerception these work by centrifugal force. The tire leans away from the lite side which picks up the beads.
@@suggesttwo I understand that now
@@WarpedPerception Can you do a wilesco steam engine?
Very cool brother 👌
Awesome 😊
your videos rock!
Sweet!
for the win! that was time well spent, yeah IDK if I need them but if I were a high mileage slabber it would be good, for the city not as useful.
Awesome video bro
Thanks
Well... now I know. Thanks for the video bud
Wouldn't adding water inside the tire behave in the same way?
I've heard it does but I would think water is too fluid.
@@WarpedPerceptionagreed, we should use mercury instead
This deserves a follow up video. Could be radiator coolent or some jello fluid
I'd be concerned with pressure buildup. Maybe an antifreeze?
@@linecraftman3907 mercury would mess up the rim and the valve...at least in long term...
Omaaigaasshh my man used the best engine to do the experiment! Long live the M113K 5.4 Kompressor!!!
I got curious after seeing your last video and did some more digging myself. It seems that another important factor is that the tire is deflecting as it makes contact with the ground, which bounces the beads up and let's them continue to distribute as the wheel speed increases, until they are locked in place. Spinning it up unloaded can cause erratic results.
This is how a self balancing washing machine works, the water does the same thing and as it runs off centre the water tries to maintain its lowest energy level i.e. equal distance from the centre of rotation.
Good science.
настоящая наука!
Over time, do they break down to powder, melt with tire heat and stick inplace for a more permanent effect, eat up the rubber inside the tire, would a thick plaste that would firm up work better, do they experience cyclical oscillations at different speeds causing vibrations, what effects do bumps have, what effects to patches of the tire have, effects of turning, why aren't tires pre balanced from the factory?
I'm torn between seeing it as Hokuspokus or believing. 🤷♂️
I prefer a correct balancing in a shop for every season (6 months) down to a weight of just 5 Gramm, inside and outside of the rim. 😉
Same here That's why even though I don't find this type of video super exciting to make I still wanted to do it, The science and the concept is there, but I also prefer a proper balance, except for big rigs as I mentioned, that's a different ballgame.
@@WarpedPerception "Super exciting" - probably not, but really interesting! 😃👍
These balls are NOT a subject over here in Europe. Maybe religious differences. 🤪
Was just talking about this 2days ago
For the mini chopper
Thank you very much man. In my experience balance beads are used on bigger tires (trucks and offroad 35” tires) cuz nobody wants to put like 20oz or 1/2 kilo of lead on the wheels and also if they do decide to balance it then the wheel would look horrible with that much weights and there is a high chance of them falling. Also when you offroad and mud and stones wedge between the tire tread it would throw it out of balance, but with these balancing beads it would get balanced again. Also as you mentioned these don’t work as good as regular weights, need slow acceleration…
Golf balls work great on bigger truck tires.
🤔
tuff
I could have sworn I've seen this same technique used in some computer optical drives.
It is likely that the cross section of the tube with beads plays a role. If the cross section is large compared to the bead size more can agglomerate. Similar to the situation in a tyre. Opposite to the example with metal balls you showed - they basically line up in a row.
True but I still put 9 oz here versus the 8 oz that it's typical in a typical car tire. So the effect should have been even more apparent
How fast do you have to go before the beads become effective?
When you had the beads in the tyre, they could spread out across the tyre and accomplish some version of 2 plane dynamic balancing.
With your tube on the outer rim you are trying to balance for that outer rim, not the inner, so there could be tyre shimmy if you spun the tyre up on a steering front wheel.
I'm like you, use a proper dynamic balancer when you can, if you want to get finicky then do an on vehicle "finish" balance.
I would also be worried about internal tyre wear, tyres are not necessarily made for internal friction wear like the beads exhibit.
A 1/4 oz imbalance on modern thin tyres might cause a flat spot too, shortening tyre life.
The only advantage of the beads as I see it, is the imbalance is being compensated for at the tyre surface, not up at the tyre rim with a clipon/stickon weight.
Think of it like this:
Put the beads in a bag, on a table. Pull the bag quickly in one direction. Do the beads go with your hand as you pull- or do they go away from your hand?
Yes exactly but and it's spinning wheel will you have centrifugal and centripetal forces I knew there had to be some other force moving them into position.
That’s going to be the hot new wheel accessory on the streets.
My top load washer has a sealed ring about 1/3 full of water at the top. You can hear water sloshing around if you shake it when the machine is empty. It still can't compensate enough for a poorly distributed load of wet clothes.
Do the same video now with something like corn syrup
You should’ve balanced it perfectly before hand and double check that it was perfectly balanced
E55 is the best car ever
It's a beast that's why I kept it, mine is like 600 ft lb of torque starting at 1800rpm.
@WarpedPerception very nice 👌 what mods?
I have an 03 E55, it's tuned by Josh at 'The Mercedes Swap Shop' ECU and TCU.
You never let the camera rotate with the tire, did you? However, I'm not sure how hard it is to do in sync. And directly connecting it to the wheel would result in totally new balance problems :D
P.S.: I love how you show stuff you never see somewhere by making them transparent :D
I did rotate the camera but the internal sensors got ripped apart, u can see them separating in some of the shots .
@@WarpedPerception I should have expected that concerning the trouble you usually go through for transparent engines and other projects. Thanks for trying :). I didn't notice that.
The beads simply increase the rotational inertia of the wheel. They do not correct the imbalace but reduce the amount off balance mass relative to the total rotating mass. The beads will only move opposite the side of the weight if the tire remains unbalanced or is spinning elliptically. These beads do not balance the tire but reduce it a bit for certain RPM ranges of the tire.
I think both are true, But from what I can see it really depends on the transition time the speed and the size of the wheel, I didn't want to go too deep into the science here but under the perfect circumstances the beads will in fact fill up the off balance side, but there is a limit I don't think it will ever be perfectly in balance because of that transition time.
One issue I see with balance beeds, adding any kind of emergency stop-leak product would not be good, since doing so will likely cause the beeds to clump.
Nice drip on the neck bro... Hope you and your family had a wonderful Easter! Love your videos!
Notification Squad!🔥🔥🔥
I KNOW they work, I've fitted my own tyres for 20 years and i add 100g of non biodegradable plastic BB pellets to each tyre during fitting AND THEY WORK,
only 1 downside is if your cruising at over 50mph and you hit a real bone smashing pothole it does throw them out of balance and make yo think something is bent, but 5 seconds later they reset and continue.
Quite honestly i believe hammering or sticking permanent balance weight to something that can see uneven wear just seems stupid.
I've read varying reviews on balance beads. The only complaint I've found is that they wear out the tire's insides. Whether that's true or not, I don't know.
If we have a perfect rigid axis that not alllows the wheel to rotate in a different center of gravity, would it work?
There would never be a completely rigid axle on a vehicle
@WarpedPerception Yes. You are correct. But hypothetically thinking, would it work on this "perfect rigid" scenario?
@@JoaoZagoSJC I don't think so No.
As soon as the wheel is accelerating or slowing down, the beads will get the wheel out of balance. This balancing technique does only work on a wheel spinning at a constant speed. On a car that in reality is changing speed all the time, it does not work, at least not on a performance car.
Plus, another ting is the gyroscopic effect that will make the beads go from the inside to the outside and vice versa if the wheel is turned left or right.
From my observation these beads work best on large tires like big rigs
Today I found out that you can build your own rims. I always wondered why some rims had bolts all around the inside edge of the rim, never even occurred to me it was that.
🙂... Yeah 3 piece wheels
You can see simmilar effect in most modern washing mashines, they are balancing themselve before spinning.
Ohhhhhhhhh
Cool product, wonder who figured this out!?
Nuclear enrichment most likely
you should check next with bb pellets if you can do a DIY version lol
Bro needs a AMG to balance his tyre
What tire mounting lube do you use?
OHHH .. good question I'll have to check.
@@WarpedPerception thank you. I have a mayflower Amazon machine and used this blue liquid that isn’t very good. I ordered some Murphy’s I hope it’s better
Can you do a longevity test? I've heard that after X amount miles these beads turn to dust and then are no longer useful. I wonder if that is true?
Great suggestion!
Could you not put a small amount of water in the tyre?
I'm old school and prefer weights, but if these beads work, then you would never have to rebalance your wheels. Plus, there's no visible weights inside your wheels, just looking for the right opportunity to fall off!
hey im off work today can i bring you the snowmobile lol i really gotta clean my yard up
cant help but wonder if it would work with water or some other liquid instead of beads.
I am still not quite sure, it´s very interesting.
Alright. Mind changed. These work. If you're just chuggin miles and you just gotta shut a tire up this is the way to go.
That's the conclusion I also came to
👏👏👏👏👏
I need Steve Mould to break this down for me.
There's no way those beads aren't absolutely destroying the inside of the tyre at high speeds, interesting-ish idea though. Stick on or Knock on weights aren't going anywhere anytime soon
I would have to agree but I don't think this is the case for large truck tires, I use stick on weights myself
So at slow speeds your tires will be out of balance and making for a poor ride?
Nah because when you're going slow you don't feel it
Interesting.....
