You may not have heard of them, but tire balancing beads are nothing new when it comes to finding economic and efficient ways to balance tires. They may not yet be as mainstream as taking your vehicle into the shop to balance your tires with weights, but they are well on their way.
Let’s learn more about tire balancing beads and see how they work.
Tire balancing beads are tiny beads that internally balance tires. You can find ceramic, glass, or a combination of both materials in them, with the better of those being ceramic. The glass beads can break down more easily, possibly causing damage to the tire’s inner lining. When used properly, these miraculous little tools will give your vehicle a smooth ride.
These are ceramic tire balancing beadsWhile balancing beads can be free inside the tire, they can also be contained in a special ring. A company called Centramatic designed a unique product that works with the same principle as balancing beads, but it is much easier to use and install.
These are special rings designed for your vehicle’s hub and sit behind the tire. Inside the ring is a set of beads that rotate around and spin out to the location where the tire is least balanced. They don’t do anything at low speeds but as speed increases the balancers go to work. We personally run these on our overland truck tires and they work great to provide a very smooth ride on the massive tires.

Basically, the beads spread themselves around the tire as the speed and vibrations increase. The upward and downward motions position the beads, keeping the wheel planted on the ground. They help keep the tire balanced regardless of what your tire picks up along the road, like snow or mud.

When the heavy spot in the tire goes up, the beads resist this, which forces them downward. The ones that aren’t needed to create balance are distributed equally on both sides of the tire, while the ones that are needed are forced downward to balance the heavy spot in the tire. The beads will now stay fixed in their position, giving you a vibration-free and balanced ride.

Tire balancing beads offer a convenient and often cost-effective way to create balance throughout the entire vehicle. They adjust as needed to what your tires are driving on, keeping you balanced, comfortable, and confident in the knowledge that your tires will get you safely where you need to go.
They’re also easy to install and often take less time than traditional balancing methods. Tire balancing beads are becoming the norm, and people seek them out now more often than in the past.
One of the biggest headaches has been getting the beads out of the tire when it comes time to replace tires. You can re-use the beads in the new tires. However, you’ll need to get the beads out without them hiding in the rim of the tire, which can cause damage. Depending on how much you spent on the beads, it may be worth it just to get new beads for the new tires.
Tire beads can be a mess when removing a tire.Other disadvantages lie in the physics of how the beads work. The beads don’t do their job without movement, so the initial acceleration can create a temporary imbalance. Speed bumps, braking, and speeding up can also cause a temporary imbalance.
The mass of the beads naturally sits at the farthest point from the rotation point.
This means you need more force to speed up. Because of this, you may notice a small decrease in fuel efficiency, especially if you have larger tires.
The beads also need to be free to work properly so if you inflate and deflate regularly moisture will build up in your tire. This causes the beads to stick together and not work properly. The Centramatic option alleviates this problem by enclosing the beads in a sealed tube.
While weights are a common option, they might not be the best option for your tires.Lead weights can fall off the tire. Since beads are inside the tire, this won’t be a problem. Because of how beads are made and how they work, they stabilize the entire axle, not just the tire, more than weights can.
Weights take more time to attach than tire beads, about 20 minutes more per wheel. When using beads, you don’t have to remove the tire. You can inject them through the air valve. Plus, weights can break down, which means you have to replace them.
With tire balancing beads, you’ll only need to install them once.

Determining how many beads a tire needs for balance doesn’t have to be a complicated equation. While different size tires require different amounts of beads, a general guideline is to use one ounce of tire beads per 13 pounds of tire. But not all beads will work on all tires.
The number of beads you need will depend on the size of your tire, so you might need to do some measuring.To make it easier, many dealers and retailers have created specific calculators and charts. All you’ll need to know is the tire width, the aspect ratio/series, and the rim size. Many times they are segmented into bags and you place the entire bag pre-weighed in the tire.
These are pre-weighed bags of beads. The entire bag is inserted into the tire.It’s possible to have too many tire balancing beads in a tire, so be sure to follow your tire requirements.
But what actually happens if you have too many? Ironically, having too many beads is almost like not having any at all in that it can cause an imbalance in the tire.
It’s easier to get too many balancing beads in a smaller tire than in a larger one. In a smaller tire, there’s not as much room for the beads to spread out evenly, and this could result in congestion in one spot, causing an imbalance because the beads can’t get to where they need to be. There’s more room for error in larger tires, so if you get too many beads in the tire, they won’t cause any problems.

Just as the amount of tire balancing beads vary, so do the costs. The best way to assess the costs versus traditional tire balancing is to determine which avenue is best for you based on both costs and time.
For traditional tire balancing services using weights added on at a shop, you can expect to pay anywhere from as little as $15 to upwards of $75.

For tire balancing beads, the cost will depend on tire size and the number of beads you need. You can spend anywhere from $5 to $20 per bag of beads. With larger tires, this cost could be more (with bags ranging anywhere in size from around four to 16 ounces). Take that amount times how many tires you have. It could be cheaper than weights and a service visit, or it could be more.
➡ In addition to balance, tires also need to maintain proper pressure. Check out our recommendations for The Best RV Tire Pressure Monitoring Systems.
For a traditional vehicle, most shops are used to using weights, and it’s usually best to stick with what they know. If, however, you’re running specialty or oversized tires, beads may be an easier and better solution. If you drive in mud and snow, beads or Centramatics are also a good option as they constantly balance as conditions change.
Using tire balancing beads may be a bit more efficient than the traditional method of bringing your vehicle in to get your tires balanced. Still, in the end, your decision has to make you feel confident and comfortable while on the road.

How unnerving drivers are, the sudden vibration from the wheel. This can happen after hitting a hole, or in case of sticking to the inside of the disk: dirt, ice, bitumen. Now, car owners can avoid imbalance if they start using balancing balls. They are also called granules or beads for balancing. Thanks to the development of Western engineers at the turn of the 20th and 21st centuries, car enthusiasts around the world can visit tire shops less frequently.
Balancing pellets have a regular round shape design. The principle of operation of the balls is as follows, under the action of centrifugal force, the granules are distributed in places where the weight imbalance is greater. During the movement, the beads are affected by an electrostatic field, and under the influence of tribostatics, the granules seem to stick to the inner surface of the tire. The more balls in the rubber, the heavier their total mass, which makes it possible to eliminate even a strong imbalance of the wheel.
The core of each granule is a component such as glass or ceramic. Outside, the core is covered with a shell of silicone material. The creators of automatic balancing were Canadian engineers from Counteract Balancing Beads Inc., from Ontario. It was they who obtained a patent for the invention in 1997. The developers presented the tire self-balancing technology based on glass microbeads. The granules had electrostatic features and a slippery silicone coating. Standard ball diameter 0.15-0.9mm. At present, the technology has not changed.
As the car moves, the beads rub against the inside of the tire, creating a tribostatic effect. The granules try to be evenly distributed over the inside of the tire. Beads accumulate in the place of greatest load and stick together. It remains in this position even after the vehicle has stopped. As a result, not only the rubber and the disc are balanced in motion, but the assembly that includes the brake disc with the hub.
It will not work to balance the entire node on the machine. Therefore, granules, in this case, are much more effective.
In order to place the balancing balls in the wheel, the spool must be unscrewed. Through the pumping fitting, it is necessary to pour the powder from the granules into the wheel. Also, the beads can be placed in the tire when flanging. Refer to the user manual for the charge volume. Then, the spool is screwed into place and the wheel is inflated.
The benefits of bead balancing are undeniable. Thanks to a dynamic process, the balance of the wheel is constantly being adjusted. For example, if ice has stuck to the inside of the disc after washing, then the granules will correct the imbalance. As soon as the ice thaws, the balls will again correct the correct rotation of the wheel, changing their location. Pros of using a microbead:
Despite the positive effect of microbeads, there were also disadvantages in its use. However, the "fly in the ointment" is quite small. Firstly, the pellets are guaranteed to scatter when the wheel is unmounted. Collecting microbeads, in the presence of a waiting queue, is not very pleasant. Secondly, some of the balls will be lost when the tire breaks. But this already belongs to the category of rare situations. The main disadvantages of bead balancing:
The use of balancing pellets still brings more benefits than losses. Each car owner must decide for himself whether to use automatic balancing.
Canada is an industrial country. Its roads are criss-crossed by heavy vehicles. Therefore, automatic balancing was created primarily for trucks. That is, the development is addressed to large tires. But even after exceeding the speed limit of 110 km / h, the effect of the balancing granules disappears, this was noticed by the drivers of road trains. The effect of beads on passenger tires has not yet been fully explored.
If you have a strong desire to purchase balancing balls, you should take into account the operating conditions. As it became clear from the materials of the article, bumpy roads and private use of expressways can reduce the effect of automatic balancing to zero. But if you are a truck owner, then this type of technological innovation will most likely be useful.
Balancing is one of the main types of wheel maintenance.
With an imbalance, the car vibrates, fuel consumption increases, tires and suspension wear out faster. An innovative solution to this problem was balancing the wheels with balls. The innovation appeared in the West, especially for heavy vehicles. However, the idea has spread in the environment of passenger wheels. What is the peculiarity of this balancing method, how the process takes place, what advantages and disadvantages this method has, more on that later.
The idea of bead balancing came from the fact that even new truck tires are sold with poor centering. As a result, the tires wear out quickly and cause damage to the suspension of the vehicle. As for balancing machines for cargo wheels, they are available only in specialized tire shops for heavy trucks. It was this shortage of specialized workshops that became the trigger for the development of the bead balancing method.
The idea was not new, as it was previously practiced by one of the American truck drivers in the mid-50s of the twentieth century.
However, it did not receive mass interest and distribution.
The American's idea was good, but far from perfect. The material of the granules did not allow to achieve the required quality of self-balancing. In 1997, Canadian engineers finalized the idea. The invention was patented by Counteract Balancing Beads Inc. Technologists have developed glass beads in a silicone shell with electrostatic properties.
When moving, the beads rub against the rubber and stick to it under the influence of tribostatics. Moreover, the beads tend to a balanced distribution. Even after stopping, the balls remain in their places. The peculiarity of this method is that there is a complex balancing of the entire assembly: wheel, hub and brake ram. Well, it can't be done on a machine.
Modern manufacturers use proppants in the production of balancing kits - granular refractory powder made of glass or ceramics. Each element has a very smooth surface, with a porosity of no more than 0.
3% and a microhardness of 7 on the Mohs scale. Sphericity and roundness of the proppant 0.9/0.9. Due to these characteristics, the balls have a lower abrasion coefficient and last longer.
The most popular are: a glass ball 0.15-0.65 mm (US patent No. 6128952) and its analogue 1.0-2.0 mm from the manufacturer TECH INTERNATIONAL. However, glass beads do not resist moisture well. As a result of friction, glass dust is formed, which is hydroscopic. It is like cement accumulates in a certain place of the tire, which leads to imbalance.
Another type of ball is made from ceramic (US Patent No. 7360846). The elements are quite smooth and durable. However, excessive strength negatively affects the rubber itself. Ceramic beads simply wear out the tire from the inside.
The balancing beads are placed in the beaded tire just before mounting or through the inflation port. In the second case: the nipple is removed, the powder is poured, and then the nipple is screwed into place.
One filling of balls can be enough for the entire period of operation of the tire.
Balancing is effective only on a flat road surface. Bumps and holes will shake the wheel, which will prevent the beads from sticking to the inside of the tire. After leaving on a flat highway, the centrifugal force of the wheel will balance. This will be enough to form the effect of tribostatics and uniform placement of beads. The action can be compared with the spin mode of a washing machine: until the laundry is distributed over the drum, the machine shakes violently.
Pay attention to the "dosage". A lot of beads - everything will appear in the wheel. Few beads - balancing will not work. In order to optimally calculate the required number of balls, you should resort to the help of special balancing powder tables.
As with any maintenance method, tire self-balancing has its advantages and disadvantages. The pluses include:

The codes do not go beyond 150mm in width. With these tires, the first number of the tire size is not the actual width, it is just a number. The M-code is what tells you the actual width.
Two rim locks opposite each other don't require any more Dyna Beads other than stated above, as they have a tendency to cancel each other out.
