Good video, something to note, the beads I see used and seem to work the best are much smaller, more to the size of larger sugar crystals, the larger the bead the less reliable they are in working each time you come to a stop and start driving again. One other thing for anyone who's not had them work, they MUST be made from something like ceramic or glass to prevent them sticking together, plastic usually doesn't work and often will make the balance worse. Thanks for the video!
Thank you! You convinced me! I couldn’t get my 69 VW bus wheels & tires balanced because no one could mount them to a spin balance machine, just like your Citroen.
Never heard of them before but I recognised the principle from dismantling a top loading washing machine years ago. The inside drum had two hollow rings, one at the top and the other at the bottom which were partially filled with water (and sealed) and serve to balance the washing during the spin cycle. It sloshes around to pool opposite, say, a large towel and compensate for its weight. Regarding a tyre and from looking at another video - the beads tend to roll to the centre of the tyre as only the bottom is flat - the rest is curved. So static balance will be quite good but dynamic not so flash. Enjoyed your video!
What a wonderful piece of knowledge from your washing machine. Thanks for sharing. And a good point on the curved tyre inside. It will indeed lessen the effect of dynamic balancing. A more elaborate setup would be needed to fully test this out.
Thanx for the video!! Best explanation ever! I have been struggling with the theory for ages because I did not know about the difference in balance when rotation around the centre of gravity! It is soo logical now!! I would do it the exact same way on my car, even thought about doing it to save money and furthermore reach perfection. Will do it now for sure. You convinced my with evidence! Love it.
Great video. One situation where balancing beads aren't ideal is if you need to use a tyre plug. They'll shred the plug to pieces and break up as a result. You just end up with a powdery ceramic mess and a plug that won't seal.
I've had dual sport motorbikes for years, The best way I found to balance the wheels for higher road speed is tyre slime in the inner tube, it makes a massive difference on the higher speed rated tyres, knobbly tyres are sometimes beyond help but it definitely helps.
Absolutely fantastic work, there is a lot of poorly informed speculation out there on balance beads. Next time i lose my weights or get imbalance coming back in i will give these a go.
Brilliant explanations thank you. As a former 2CV owner for ten years, and have land rovers now; really enjoyed your Citroen Logic 👍. I think my 2CV wheels got balanced on a bubble balancer. But my land rover wheels might balance with steel ball bearings quite well 🤔, and I've heard they use golf balls in lorry wheels 😃
I had oddball (stock) wheels on my 1958 Apache 3/4 ton pickup. They were 17.5 inch wheels, so there were only two tire options to run the stock wheels, both were luggy military tires. No local shop was equipped to balance them so I used beads. Anyway, I used the smaller beads that can go through the tire stem. The trick to get them into the wheel without jamming or clogging, I used a funnel and an engraving tool to vibrate the valve stem and keep the beads rolling into the wheel. Takes a little time and patience, but a lot less energy and risk than breaking the tire bead and tossing them in that way. Worked like a charm.
wish i had known about balance beads way back when i had an R4 that also had wheels that no shop could mount on their modern balancing machines. main issue was in the front....on the back the tires could hop up and down 20cm and you wouldn't even notice it.
Finally you gave me the answer I've been looking for. It is the center of gravity and not the periphery, or the center of the wheel and not the outermost edge that causes the dis-balance. I've been running beads on all my cars since about 15 years ago no problem until the tires get quite old and need replacing. I run plastic bb pellets.
@@marco7716 Sehe ich auch so, es ist doch schön wenn man anderen helfen kann. Auch wenn in diesem Video nur das wissen bereichert wird, und wissbegierig sollten wir alle sein und bleiben.
What a great video, thanks indeed. I've recently fitted balancing beads (tiny ones that do (eventually) fit through the valve stem into my tubes - 40 minutes per wheel to get them in! It is interesting that you are running tubeless? Does your 2CV have safety rims? This is a long standing debate!) My Renaults have the same size rims as yours and my early 4CV spider wheels can only be balanced statically at my local tyre place. They can balance my 15" disc wheels on the R8 but this doesn't reliably stop vibration at 100 kph. I"ve not finished testing the results of the beads yet and just remembered I might still have balance weights on the inside of the wheels, so need to pull them off. I have checked for roundness and sideways wobble, and they are OK within 1-2 mm. Thanks again! Really interesting.
Thanks for the comment. My rims didn't look like safety rims (but I didn't really have a good look inside, so maybe they are). I hope those beads work for you. There are much more variables involved than with traditional balancing, so I am not sure if it will always work. Let us know how you go.
Tyre Balancing Beads - I have been using them on my Motorcycles for last 8 years. Biggest benefit is Beads balance the life of tyre, wheel weights do not. Tyre can irregularly wear and dirt, mud, tar rocks sick to inside of rims changing the balance.
you can balace those wheels on the car by letting the wheel in the air and letting it rotate with the heavy spot at the bottom, then add weights at the top, rotate the wheel and see where it starts to accelerate or decelerate the rotation. to find the heavy spot again and so on
Had the same problem with mud terrain tyres on my Toyota LC could not balance them properly for love nor money, put in balancing weights and presto no more vibrations!
I had problems with the Counteract beads' valve core that has the filter in it. They do not work on metal valve stems TP543 (stamped on stem). TP544 are longer and work fine. In the former the core cannot go in far enough making impossible to depress the valve core. On one tire, the filter got stuck in the stem preventing me from even using a standard core. Counteract, the company, was totally clueless about this.
The real explanation is different. The balancing effect of the static imbalance only occurs when the rotational speed of the wheel is higher than the first natural frequency of the wheel. The first natural frequency is determined by the suspended mass and the stiffness of the suspension. The maximum deflection occurs opposite the heavy spot. The dynamic balancing effect depends on two other modes of vibration. The natural frequencies of these modes are determined by the mass moment of inertia of the wheel and the torsional stiffness along two axes. If higher modes of vibration are active, either because of high speed or rough road surfaces, the balancing effect can decrease or vanish. Even amplification of the vibration is possible.
Great video! Super hack! Have you experienced internal tire wesring due beads friction? How often do you change beads since they usually tent to crash and break eventually?
I don't have any long-term experience with the beads. I will now check every 5000 km if they have already turned to dust and if there has been abrasion on the tyre insides. If I find that they are not worth it in the end I'll do another video about it.
Maybe I missed it. Did you take into account the downpressure on the tire from the vehicle's weight? (There is a flatter spot where rubber meets the road)
ShOcK & AWE eXplanation (formally Twitter). You R the "Gravitational Whisperer".Thank you for that Infotainment. This is all going on my resume Cheers from So.Ca.USA 3rd House On the Left (call before you stop by:)
The vibrations shown at the beginning are due to the road - if it were caused by the tyre “imbalance” the wheels would have come off - also the steering wheel does not shudder!
The Australian ABC beads are larger than most. That means they don't fit through the valve stem, but they will roll better inside the tyre. So it could be that they work better.
Very interesting, and well presented, but...in 50 years of 2CV {and Dyane} ownership {350,000+ miles, with several cars} I have never had to have a tyre balanced. Two other things come to mind, firstly, on a few occassions I have used inner tubes in "leaky rims", with no ill effects {or balancing needed} ...and secondly.could long term use of these beads cause any damage to the inside of the tyre {2CV tyres, are, by the nature of their size and the limited power of the car, long lasting}
You touched a very good question about the long term effect. I'm sure the beads have at least some abrasive effect on the tyre inside. And another question to add is: how long until the beads turn into dust? I don't know and would like to learn about some long-distance experience with these things. I'll definitely make another video if I find after X thousand kilometres that they are not worth it.
It should work on scooter tyres as well. But make sure that any vibrations in scooter tyres are really caused by imbalance and not unevenly worn rubber. Imbalance vibrations only occur at fairly high speeds.
It should work with a fluid. Look at the comment before yours. Kenmercer2721 found a balancing mechanism in his washing machine drum that uses the same principle but with fluid in hollow rings.
Theoretically nothing. Without an imbalance to start with the beads would distribute themselves evenly around the tyre, which would remain balanced. If the tyre got imbalanced one day (e.g. through uneven wear) the beads would then balance it.
No negative effects. I've got beads in my mud tires that were sticky weight balanced. Keeps them smooth when mud and gunk are stuck in the wheels throwing out the static balance.
You don't need any balancing beads for this car. For this car you will need a scrap press. My rule, with which I got through the world very well, was always: no cars with an F. No Ford, no Fiat, no French car. 😂🤣 But joking aside, very informative video, very well explained.
@@chriswalker4272 exact... I had once a Ferrari from a friend and i dislike this cars. This is not my world. Beside the fact they are really expensive in maintenance and repair. I like big limousines or trucks with a good V8 engine and no Italian high sophisticated V12 shit.
Wow..... never trust someone wearing crocks to explain anything. 1. Do not run a tire on a jackstand at those speeds. The tire being out of balance can cause the whole wheel to bounce off the jackstand. 2. Powders, beads and centramatic type products (any dynamic balancer) REQUIRE movement (bounce) to distribute the beads, powder around inside the tire until the bounce stops. As the tire bounces up and down the beads along the front of the tire (the near vertical part ahead of the center) and along the back near vertical will have the inertial mass to stay at the velocity of the rotation at that distance from the center. As the wheel assembly "bounces" due to out of balance, the tire will accelerate past the beads on the up bounce, and the opposite on the down. The beads at the top and bottom do not move. This moves the beads or powder around the tire until the bouncing from the out of balance stops. This system is used on all kinds of rotating equipment, including washing machines. The one thing in common is they are suspended by springs or a mounting system that can allow movement. Please do not try to spun balance a tire with beads in it already. If you must, take the beads out (dismount the tire and remount it sans beads) then spin balance if possible. Only then add the beads or powders. This will ensure they work and are not trying to balance 5oz of inbalance with 3 oz of beads.
@2CVCult-zl8eo you don't understand.... without the compliance of the tire the beads may not distribute properly and at higher speeds can cause an imbalance that will hop the axle right off the jackstand.
I find it hilarious that you have no idea what "Oh-Zeds" are...(Though I had not heard "Zed" used in decades!) "oz" (ounces, 16 in US Pound - WE STILL USE THEM EVERY DAY) yet we Americans are subjected to that asinine metric system you use....(I work in the Aftermarket Motorcycle Parts business with Harley and Honda being our biggest markets...I hate the metric system!).... FYI 1oz = 28.3495 Grams. - FYI X 2 - Tires on vehicles today use Bastardized Sizing... 235/75/15 - Metric MM Width / Aspect Ratio / Rim size in INCHES! - Figure THAT out!
I had my wheels balanced with weights on a machine and the result was less than desirable. This has often been the case in my previous experiences. I introduced tire beads pneumatically through the stems, looking for a solution. At 1st, I kept the metallic balancing weights in place while noting some weights were quite large and their placement made no sense from a dynamic perspective. The results with beads and weights were somewhat improved, yet remained intolerable so I removed the external metallic weights. The results were dramatically improved, as good as I can recall any previous balancing and now quite acceptable. So I suggest when using balance beads, removing the external metallic weights may be necessary to fully benefit frome the self-balancing effect.
Excellent comment. I would also recommend to do a road test first after removing the weights, maybe all is good already. Sometimes the weights cause the vibration (wrongly placed or tyre has changed over time and weights became "outdated").
@@2CVCult-zl8eo My guess is the weights were causing vibration. They locations they were placed and the large size of a few of them was highly questionable. There were two large weights (4 inchs each!) placed next to each other on the inside and no weights on the outside of any wheel. None of it made any sense to me...
Finally! An explanation, well done. Thank you!

You can balance that tire with a motorcycle tire balancer.
Couldn't you just balance it with a bubble balancer? Seems easy enough to do rather than all that...
These wheels don't fit on a bubble level balancer.
As a tire wears it’ll change balance. The beads should keep balance through the life of the tire.
