It is amazing that the tire withstands so many deformations during its lifetime without getting tired.

I worked at a tire shop for a couple years, I remember one time I popped open a big truck tire and the entire thing was FULL of balance beads. The customer was complaining about the truck pulling to the right and a severe vibration at high speeds. It probably had three gallons of balance beads. That was an interesting conversation with him

50 mph in the city at night with his sunglasses on, looking at his phone driving 😂.

The engineers who figure out tire construction materials & methods are brilliant!! Watching what a tire goes through has given me a whole new level of respect.😄

I've always wanted to know if balancing beads work and how they work! Thank you!!

Complaining about other drivers while hooning through city areas on destroyed tire(s) with cell phone in hand. Excellent.

I'm more impressed with the GoPro staying attached. Some serious adhesive.

Briefly studied this in engineering school. For balance beads to work the tire has to spin out of concentric. Won’t give you consistent results on spin balancer because the wheel is held firm. 2oz out of balance nothing to brag about. Some have good luck with balance beads. For others when the wheel hits a bump it spins out of concentric, moving the beads, which then have to move back into place. A bump from the road followed by a bump from imbalance. And then there is the issue of having to rebalance every time the wheel starts rolling. Some beads are sticky or use static electricity to stay in contact with the tire. That I know, OTR trucks simply do not balance any but possibly the steering tires. And use weights. Good old fashioned balancing works. There is a reason your new car doesn’t come from the factory with balance beads.

I’ve eaten a couple spoonfuls of these before my recent gymnastics competitions with AMAZING results! I’m off to nationals next month and hope to get a sponsor.

They work because the tire is rotating around its *center of mass*. If the tire has a heavy spot, the center of mass is going to be offset towards it, Meaning even though the heavy spot itself wants to be flung outward from a static reference frame, from the rotating reference frame of the tire, the heavy spot is actually staying closer to the center and the light spot is being flung outwards the farthest. The beads, which are free to move and not a connected to the tire at all only move via centripetal force of the tire trying to pull them back to the center, and they'll collect in the high spot which is the light spot.

looking at a video, driving in urban traffic, at night, IN SUNGLASSES. SUPER GENIUS

I knew they worked, I know a lot of big mud tire guys that use them because it’s almost impossible to balance those tires. But it’s so cool to see them in action. 10/10 best use of a GoPro this year.

Really makes me appreciate how tires warm up so much as you drive seeing them deform so quickly in motion.

Seeing the funnel inside the tire as the air drained from the tire was a real Warped Perception moment. Awesome

Ive been using ceramic balance beads in all my truck, car and motorcycle tires for years. They work awesome. You must put the correct amount in the tire depending on tire size and tread width or you can have an out of balance situation from too many beads. You get a random harmonic imbalance that comes and goes when you have too many beads installed. I swear by ceramic beads. Tires last longer and they perfectly rebalance the tire every time yhe tire gets to 15mph. Ceramic beads are reuseable too. Causes no damage to tire, wheel or tps sensors.

Amazing how well they work. In India we are using rice instead. Works the same way, but you have to replace the rice at least once a year. But we have enough of it, and it isn't very expensive.

I've been using these for about a year now. I was initially under the impression they found the inbalance area and stuck to it. Your video cleared that up. They don't stick, instead it's a continuous move to find the inbalance. Awesome video. Be careful and follow the directions. Amount matters for tire size. 😊

A true Chicagoan! Drives a rustbucket onto the streets with tyres that any cop would have a fit at, slams the horn as if his lizard brain was born with the reflex when some douche cuts him off and wears sunglasses at night. Loved this video, didn't think the balance beads would work that well! Never stop

I was with you, scratching my head until reading the comments triggered an understanding. The short version is... the wheel accelerates TOWARD the heavy side, the beads want to get left behind and, being free to move, collect on the light side. Intuition is not always our friend when it comes to physics. Great great video!

Yes they work, i put them in my land cruiser MT tyres after i could not get them balanced with weights, the work well. I had a flat after about 25.000 km and there was no damage in the tyre and beads were clean, no dust or other debris.

Probably 70 percent of heavy truck tires are balanced with beads. I worked 11 years in a shop with "tire" in it's name. If you would have poured a second bag of beads in your tire, it would have spun up at zero on the balancer. I have spun tires on the balancer, corrected with weights, and driven the truck. I then went back to the shop, added slightly more beads by weight than I used to balance the tire, stripped off the weights, and drove again. EVERY TIME I did this, (like 10 or 12 times), the truck was smoother with the beads. Mind you, the steering wheel ( I always did this to left front) Kind of "chugged" until the tire had been at speed for 10 or 15 seconds or so. Then it was as smooth as road force imbalance could let it be. After my research, we built the cost of beads into the price of all front tires on 19.5 inch rims and larger. All of our medium and heavy duty customers kept coming back, saying "xxx"s tires are 20 bucks cheaper, but yours run better" I understand why it is counterintuitive, but I think the beads bounce off the heavy spots because they are moving faster away from the axle centerline than the light spots.This results in the beads "finding" the right position for the tire AT THAT MOMENT. Just my opinion, hope it helps.

I used to drive 250 miles a night on gravel roads, on wet nights gravel would get stuck on the inside my rims and when I would hit pavement the wheels were unbalanced. I started using balance beads and they worked great for the next 2 years I did that job.

I've been running balancing beads for 9 years and over 20,000 miles in my Harley dresser motorcycle, the balance is perfect. The tires still have a few thousand miles to go on them, I contribute the high milage to continuous perfect balance. When I change the tires, I'll see the effect the beads have on the interior.

I run beads in all my truck tires, I've never had a smoother ride out of tires over 35 inchs. I've heard horror stories about Milestar Patagonia's being incredibly hard to balance but I've been through two sets of 38's on my Jeep and the beads work perfectly.

I'm impressed those janky ass tires survived that jankier ass street! I tried beads for the first time recently in some bigger offroad tires and now I'm a believer.

Don't google "vibrating beads inside cavity"

I had been using them on my motorcycles for over 20 years, and I had got thousands of miles more on every tire than regular balancing. Not only did my tires last forever, but the ride was smoother and no tire cupping, especially on my second gen Honda Goldwing that are famously knowing for front-end vibration. I had always waited to use them on the second set of tires and beyong on every new bike, but at this point, it is the first modification I do when I get a new bike. By the way, I always use a fresh set of beads on new tires. Thanks for the video.

I became a firm believer in them the first time I used them in my RV tires. I have split rings on one of my vintage RV's and I couldn't keep the weights from flipping off. Because they are split rings, they have tubes. Dyna beads makes a tube friendly bead that you send through the valve stem. The first time I used them I was stunned at this voodoo magic! Great Video BTW!

I never thought the beads would work for the same reasons you did. I assumed they would gather at the heavy part and make it even worse. You learn something every day. Cool video.

Thanks , this is amazing ! I've used them in Motorsickle tires but was always skeptical to be honest , I don't know if this answers "do they work ?" I think the balance machine said "yes" and I sure loved seeing the tire tread & sidewall doing their thang , friggin' amazing...

Welcome to a prime practical example of the quantum existence where the act of trying/attempting to observe the thing you want to observe directly affects the outcome of it.

I used the balance beads in both my Silverado and my wife's GMC Envoy's new tires and was very impressed. In both I just tossed the beads in still in the bag. I first tried to put them in through the valve stem and was unsuccessful. My only concern is if I need a tire repair will the shop leave them in place. Two thumbs up for balance beads!

I bet shops love these when they go spilling everywhere during a tire replacement..

I have no freaking clue what I expected but wow thank you so much.

This is also how your washing machine balances in the spin cycle. They use either a couple of balls, beads like this, or a ring of fluid (infinitesimally small beads). You normally don't notice them on top-loaders, but you can hear them roll around when you manually rotate a front-loader.

I use them on my 05 Suburban tires and they work very well. When I put the beads in mine I dumped them in the tire after you put the inside bead on the rim then dump the beads on the opposite side of the air valve and then mount the outer bead on the rim and inflate the tire,no mess with beads all over the bead seat getting stuck between the rim and the bead on the tire.

👍 this video was fantastic. I've used balancing beads in my motorcycles for years. I balance the rims with normal weights (1x, rims don't usually go out of balance) and after that i just put 20g per wheel. If any stone gets trapped in the thread the beads work their "magic". From what I've read, the beads start working above 60kmh.

I've been using them in my motorcycle tires for a decade and 150,000 miles. They work great!!! I use the steel beads because you can reuse them.

I sold the first product 25 years ago. The way we explained it then, was the heavy spot on the assembly had more impact force as it contacted the ground, thereby causing the beads to migrate to the lower impact area. Quantity of beads versus tire size was critical. I helped get it in a LSR truck that raced on the Salt Flats doing over 200MPH with airplane tires. worked great.

It's amazing that so many people didn't know that while driving, the tire flexes with every revolution of the wheel.

Never heard of those, looks pretty cool. amazing little things, did not expect them to do a lot.

If nothing else, visually this is one of the most interesting videos I've seen in a long while!

I gotta say, this is one of the coolest tire videos I have ever seen in my life.

Been using them for 10 years in all my vehicle and motorcycle tires. I get about 10000-15000 more miles out of a vehicle tire now and probably 2500 on a motorcycle. They ride really good. I absolutely love them.

This has brought to my attention how much flexing a time does in three dimensions! It is amazing they last so long! Excellent video. Thanks for posting!

Now this is an awesome video!!! From what we could see the beads were evenly distributed, but to balance the GO-PRO the beads would be out of view. Perhaps next time TWO GO-PROs???

Screw the beads, just seeing how the tire reacts to driving is cool and the flexing while turning is mind blowing.

Take the valve out of the valve stem, then pour the beads in. Or just toss the whole bag inside before mounting, and the thin plastic bag will quickly rupture once driving. Just sweep them up pronto if they spill on the ground, because they are quite slippery (it's literally like walking on ball bearings) Source: Hubby is a retread tech, and appreciates the inside view!

I spent 2,500 bucks on a set of 33x12.50-20 wheels and tires for my truck and the shop recommended balance beads cuz they were the new best way to go. A horrible shake around 45 mph that lasted to around 70 and 3 trips back to the tire shop later they took the beads out and balanced them with some stick on weights. problem solved. Not sure why they wouldn't work for me but they wouldn't. Maybe someday ill try a different application but for now i am not a believer.

I've actually had great experiance with balance beads in Harley tires. You can definitely feel an initial gyroscopic effect during initial roll from a stop, which disappears when at road speeds. After that, smoooth sailing

I have balance beads in my three trailers and my 2 motorcycles, and I have no complaints ,they work great. There are websites that you put in the tire size of motorcycle, trailers, trucks, or cars and it will show you the amount of weight of beads you need for the tires

I first used balance beads when I worked at McCarthy tires on 18 wheelers I've since ran them in my motorcycle and they really work great I recommend them all the time.

They’re in great shape?!? Hell no! Buy new tires that aren’t falling apart.

Always wanted to know how those worked, this will be cool. I remember working at a tire shop and being surprised when all these beads were in a tire!

Couple things I learned over the years, Beads work good if installed properly. The balancer may not show them as well because they do need the bumps in the roads to help situate them after centrifugal force has them stuck to the tire. The vibrations will help them spread to where they need to go. Also, I had bad luck with them when they were installed by throwing the 'Bag of beads" in the tire before tire install. Instructions say the bag will disintegrate after a while, but that take way too long. You'll get intermittent out of balance feel, and it will change every time you stop and start again because the bag remnants create a barrier and catch a bunch of the beads throwing the tire out of balance again. The way you installed them is the best and most effective. 👍

I've never heard of them, but ive been using tire balancing fluid (I don't remember the brand, got a bottle in the barn) for 50 years in my motorcycles. Use tubes & just switch the tube to the new tire. Always worked great.

This cat ignores physics and Google, but nails KZfaq videos that spotlight his balance cluelessness. You do you, bro.

As you can see my tires are in great shape 😂😂😂

Been using them for a couple years now. They are amazing.

I love that sound inside the tire, it’s like entering into another dimension in space

Dude you’re one of the most clever AND cool guy on KZfaq. I’m a car guy, whole studies and career into automotive domain, first I’ve never heard about these beads here in France and I’m super curious too, and two…… I’VE NEVER SEEN FROM INSIDE A TIRE WHILE DRIVING THIS IS GENIUS AND HUMONGOUS INTERESTING TO ME !!!!!! I mean just watching how a tire works from inside this is fkng fascinating !! And now I’m even more hooked to understand how these beads work……. I LOVE YOUR VIDEOS.

2:34 Right? Just dump it in! GoPro in a tire 2.0 This was cool. Thx. Makes you wonder if "Balance Beads" should be SOP on vehicles.

No surprise to me that the balancing bit worked. 45 years ago, I used a semi-viscous motorcycle tyre sealant for the purpose of sealing any future punctures. The manufacturers also claimed that it automatically balanced the tyre (which it seemed to) and caused the tyre to run a bit cooler (which I couldn't test).

I’ve been using balance beads in my Jeep tyres for years. They work great!

Now I know your daughter dressed you this morning. lol Cool video.

Interesting! I never heard about tire beads. As you showed, they seem to be quite effective. Thanks Matt!

Great video! I use BBs and antifreeze to balance the mud tires on my lifted Chevy. The faster I drive, the better the tires balance out.

Balance beads work very well. I have them in my car hauling trailer, and it tows so smoothly, I almost don't even know it's back there.

Wow, this was a really cool video. I never thought these balance beads would do much.

the danny duncan shirt is so fire lmao

Neat video having the camera in the tire/rim combo. I use these on my atv I use for work and often get to 40-45mph. Smoothed it out considerably.

What's also good about balancing beads is that it balances the entire rotating mass, meaning the rotor or drum.

This about to be a banger

I had no idea balance beads work so well. Thanks, great video! Now we need one with green tire slime and 3 plugs, with one near the side wall- for your fans from NYC. 😂

I’ve been using the balance beads for years in my motorcycle they seem to work great. I use a 1/4” clear tube over the valve stem and one of those plunge cutters without the blade for the vibration. I have to use this method because they’re tubed tires. Those other valves may have been “filtered” valves because sometimes the beads can get caught in the valve. I don’t have the filtered valves so I make sure the valve stem is on the bottom and tap it a couple of times just to make sure no beads get caught in the valve.

They work really well on motorcycles. I was skeptical at first, but it worked. Never tried on a regular vehicle.

Really cool experiment! Also nice Danny Duncan shirt! I loved the video you did with them. ❤

I used to have trouble watching you, couldnt reaonate with you or your content. I dont know what it was but it was irrational and unjustified. Im very glad i found your content and am impressed with everything youve done. Keep it up, mad quality videos, wish i was able to do a lot of the same stuff you do my dude!

The best use of a GoPro I've seen yet.

I used to install counteract in tires at an old job. It's pretty cool seeing it in action. We had pre-weighed bags of the beads though. Made it much easier than your method.

I was thinking about purchasing this tech for my car and this is the exact type of testing I was looking for! Thank you so much for posting this!! Have you considered testing centramatics or balance master wheel balancers too? Those are supposed to be the best in the business for balancing tires and I'd love to see their comparison in testing, especially on the balancing machine. Also, I've only heard about the upsides to balance beads, but can't seem to find any down sides which makes me suspicious. I'm curious if they could cause noise, damage any tpms sensors, wear the inside of the tires, etc? I just don't know but I do know that every product has it's pros and cons and would be interested in learning about them for balance beads and automatic wheel balances like centramatics and balance masters. Thanks again!

After a while those beads start to tear up the tire from the inside. I’ve seen and heard of rubber “Powder” coming off from the inside because of the beads. This stopped me from using them on my Harley.

I am impressed that your Gopro survived after it came off the wheel. It must have gone through a lot of violent tumbling. Thanks for the video!

This is going to make me more humble with the gas pedal when driving from now on. 😅😅 I have so much respect for Tyres. Thank you.

Take an old DVD drive from your computer and rock it from side to side. You will hear the balls rolling inside. This the same dynamic balancing method is used as in this video.

Thanks for this vid. I'm amazed at how the beads actually work and I'm surprised the gopro survived!!

Funny intro. Super degradated tire in a fancy shop garage. I always thought tires had tubes in them so that was very interesting to find out.

I ran balancing beats for 6years+ on multiple cars. And yes they do work very well. Just make sure you have 1oz more in the tires per tire. The extra weight makes it even smoother on 100mph and more. The vibration you saw each time the tire hits the surface ground causes the not balanced beats to move a bit till they hit the correct spot to balancing out the whole tire assembly.

I dont know why but watching the beads inside the tire was hilarious as hell You could have an entire video of just that stuff and I'd watch it

Dude thank you. I can't believe that this is the first time I've seen the inside of a tire while in motion and under load!!! Very interesting and informative!!!👍😎💯♥️🇨🇦

I watched this just to see go pro video from inside a tire. Worth the price of admission right there, Great Job!! That the beads work is kind of freaky, seems too good to be true so I figured it was just more snake oil. Super video, sir!

I'm so glad you finally found a good use for a GoPro.

I had a flat spot on my motorcycle & put in a bottle of slim. & it worked. Smooth.

Interesting. I ran balance beads in my motorcycle tires for years, both in an 1100 Yamaha and an 1800 Goldwing.. They mostly helped in balancing but did nothing to affect unusual tire wear. I finally went to using Centramatic tire balancers that mounted outside on the wheel on the Goldwing. Smooth as glass to 120 and for the first time with a motorcycle I'm seeing tires wear out all the way without any cupping, scuffing, or other unusual wear patterns. I previously had to change out tires long before the tread was gone, now I'm getting almost twice the mileage.

As a trailblazer fanatic, I love that hooptie. Especially those wheels.

yessir! I have been using Dyna Beads, 35 years on motorcycles.

New appreciation for what tires do for sure.

You're supposed to keep the beads in the little bag they come in. You put that pack of beads, still in the bag into the tire when you are mounting the tire. The bag splits open releasing the beads once the tire starts rolling. Its right there in the directions that you didn't read. Also in the directions are info about the valve stems and cores. Traditional valve cores can trap a bead under it and cause it to leak. The cores that come with the beads prevent that, so go install those cores.

Great video. The tire jumps the direction of the heavy spot. The inertia of the beads cause them not follow. After several jumps with the beads going the opposite direction of the heavy spot the tire balances and beads stay in place.

A similar approach has been used in computer optical drives, to prevent unbalanced discs from causing excessive vibration and noise. The spindle motor contains some loose ball bearings that function similarly to those balance beads.
