Here are the basics of how to break the bead on a tire, and how BeadBuster can help.
For starters, there are
TWO STEPS in the de-mounting process of any tire change:

‘Break’ the tire bead loose with a Bead Breaker

 

 

Remove the Tire with Tire Irons

The BeadBuster tool only helps with the 1st step.
But critically, the 1st step is usually the hardest. Dislodging the tire bead from the rim (aka ‘Breaking’ the Bead) can be almost impossible without the right setup and tools.  We also sell great, Heavy Duty tire irons for Step 2.

The tire bead is held in place between the lip of the rim, and a small bump-like feature called the
“Bead Retainer”.

 

The tire seals around its inside diameter, and is held in place with air pressure; the bead retainer’s job is to keep the tire from moving and losing its seal under side loading.
 A heavy steel cable runs through the bead, and keeps the tire from expanding and losing the seal.

 

On an ATV, the bead retainer is quite large due to the extreme use that the tire sees on the trail, and relatively low air pressures that are run.  The bead retainer does such a good job that it is very difficult to get the bead past it when its time change out a worn or damaged tire.

Shown below is a conventional bead breaker, it uses a mechanism that we call the
“Shoe & Lever” to break the beads.  A curved metal ‘shoe’ pushes down next to the bead using a long lever.
This works OK for some kinds of tires, like cars, trailers, and some motorcycles.  But it does not work well on the heavier tires and more extreme rims found on ATV’s, Side by Sides, Offroad Trucks, Adventure and Touring Motorcycles, and the list goes on.  Often, using this tool on those stubborn tires will result in a damaged tool, tire & wheel, and a whole lot of wasted time and frustration.

The problem is that, by its design, the shoe pushes down on the
SIDEWALL next to the bead, which is thin rubber.  If the bead puts up a fight, the shoe will slide down the sidewall, because the steel cord will not budge over the bead retainer.  This kind of bead breaker just doesn’t have the proper mechanical advantage.

We’ve seen many creative alternatives to this Shoe & Lever bead breaker…all of which still don’t work very well, are dangerous, and not a solid, reliable technique for breaking loose stubborn beads.

The BeadBuster difference

Sometimes you have to be resourceful, but we at BeadBuster knew there had to be a better way, and we came up with one.

The BeadBuster tire bead breaker is a new type of mechanism that we call the
“Clamp & Ram”, due to how the tool clamps onto the rim, and the Ram foot pushes down on the bead and breaks it loose. Learn how to break the bead on a tire with a BeadBuster below.

Breaking beads with the BeadBuster couldn’t be any easier.

All you do is get the feet in between the lip of the rim and the tire bead, and the Clamp Screw sucks the feet in, partially breaking the bead in that area.

Then the ram foot pushes down, and completely breaks the tire bead free of the bead retainer.

Usually all the way around the rim with pushing down on just one spot.

The reason the BeadBuster is superior to any other bead breaker is that it pushes down on the steel cord inside the tire bead, NOT the sidewall.

When the steel cord gets pushed down, the rest of the tire is coming with it, no matter what its condition is.
By design, the BeadBuster HAS to work…and it does every time.
And it doesn’t matter the width, diameter, or type of rim. The BeadBuster does not need adjusted, you just clamp it and break it loose. It works on everything from Go-Karts to light Aircraft.

How To Break A Tire Bead: 5 Steps To Follow

Getting trash and rubbish inside tires happens quite a lot, especially with vehicle owners having many off-road trips. To be more specific, the trash will make its way onto and into the tire. And this is the reason why we need to break a tire bead.  

Tire bead is the innermost diameter of the tire that connects with the wheel rim. Most people think that breaking a tire bead is common knowledge for every driver. However, not that many car owners know how to break a tire bead. As long as the bead stays intact, there is no gap to form between the rim and the outer edge of the tire. Basically, there is no way to fix the tire from the inside, which is another reason to learn how to break a tire bead. In this article, our car experts will tell you what tool you need to break the tire, as well as how to do it.

Bead Breakers

Before getting to know how to break a tire bead, it is essential to acknowledge your best tool. Bead breaker is the car tool with the purpose of separating tires from their rims. Different types of bead breakers have different ways of using. So let’s jump right into answering the question “how to break a bead on a tire“:

Plier Type Mechanism

This bead breaker uses a plier-type tool in order to apply force between the bead and the rim’s lip. The tool has a spike to perform this task. To be more precise, this spike imposes a force on the bead and the sidewall of the tire to separate them. Therefore, it weakens and removes their connection. This plier type mechanism is amazingly effective and can get the job done very fast. However, it has its disadvantages. The spike is like a double-edge knife that might leave scratches on the surface and on the wheels themselves. Not to mention, this plier type mechanism is very heavy and big, which requires your full body weight in order to get the results.

Shoe and Lever Mechanism

Just like the name said, the shoe and lever mechanism has a shoe-shaped tool which can apply pressure on the sidewall of the tire. In order to break the connection between the bead and the rim, car owners must push the sidewall. This is, without a doubt, the most popular bead breaker among all, since it works amazingly well on motorcycle tires, new passenger vehicle tires, as well as trailers’ tires. The benefits of this bead breakers are quite a lot: First of all, it is very low cost, so anyone can purchase one for their vehicle. Second of all, the way to use it is quite simple and easy to follow. Last of all, it is made for passenger cars’ tires.

On the other hand, it does not work very well with old and hard-to-change tires. Since the shoe and lever mechanism is also large and bulky, this breaker can only be used on some particular types of tires. 

Clamp and Ram Mechanism

Last but not least, the quickest and most efficient break beads of all time: Clamp and Ram Mechanism. If the first two mechanisms cannot solve the problem with difficult-to-replace tires, this bead breaker can deal with all of them. In order to make it work, this machine uses a pointed foot tool with the purpose of exploiting the space between the bead and the rim’s lip. Not to mention, this bead breaker also has a padded clamp. The part can go inside the sidewall with little effort. Long story short, not only this machine works with all types of tires with minimal human effort, it also causes no harm to the sidewall or to the tires. However, it is quite costly.

How To Break A Tire Bead

Knowing that you are already familiar with all the tools, let’s answer the question of “How to break a Tire Bead?”. In order to perform this task, car owners need to follow these steps:

Step 1: Prepare the Tool

No warrior goes barehand into the war. Here is the tool list that you need:

  • Hammer
  • Breaker bar
  • 3 tyre levers
  • A handle
  • A valve core tool

Step 2: Remove the Valve Core

In order to start breaking tire bead, car owners need to be taken off the valve core to release air pressure out. This step needs to perform before and during the first stages.

When the valve core is removed, car owners need to put the wheel under the brace. By performing this, the air will be pushed out and we can easily take the wheel off the rim. Just remember to wait until all the air pressure is lost in order to remove the wheel. A little tip to check the tire is to press your hands against the tire’s surface. 

Step 3: Place Tire on a Surface

In this step, car owners need to lay the tire on a hard surface. After that, you should position the breaker bar between the rim and tire. Before proceeding to the following step, it is suggested to check if the tapered edge of the breaker bar is aimed toward the tire, not the rim. 

Also, a solid surface is the necessary factor in this step, since it is capable of handling the pressure you are going to apply on.

Step 4: Slide Breaker Bar between the Tire and the Rim

The next step of “How to break a tire bead” is to slide the breaker bar between the rim and the tire. It is essential to check if the pointed edge of the breaker bar points away from the tire’s rim. The reason for this is that the edge is highly sharp and might create scratches inside. For that reason, car owners might want to aim the bar to the tire, not the rim. 

Step 5: Hit Breaker Bar with a Hammer

When the breaker is already steadying in the distance between the rim and the tire, it is time to hit it with a hammer with the purpose of breaking tire bead. Wait, we are not telling you to destroy the tire! The purpose of doing this is to drive the breaker inside. So keep hitting it and pushing the breaker bar toward the ground until the bead is broken and we can tell by a small pop sound.

Step 6: Rotate Around the Tire’s Inside

Last step of how to break a tire bead is to remove the tire of the rim. Car owners are recommended to rotate the breaker around the tire’s inside while continuing hammering from above. Keep doing that until the tire is off the rim, then turn around and do the same with the opposite side of the tire.

Conclusion

Many people might be wondering, why do drivers need to learn how to break a tire bead? One of the reasons is that the process is simple to follow, even with beginning car owners. All drivers need is thirty minutes and this instruction. Another reason that it provides a great help in cleaning up debris and dirt inside the tire. By breaking the bead, vehicle owners can remove the rubbish inside and reduce the future problems. The last reason is to save the cost of paying a car repairman, since you can remove the tire from its rim by yourself. 

 

Basic disc damage: when to repair and when

Not all wheel disc “injuries” can be repaired. Often it is better to replace a failed disc than to wait until it ruins a tire or suspension. One way or another, seasonal change of shoes is the best reason to solve problems with discs at the same time.

Tire damage: here are some that you can (and cannot) fix yourself

Wheels of different types differ significantly not only in terms of characteristics, but also in terms of damage types. The most affordable and common - stamped. Alloy wheels are more expensive, but they also look better, although they do not have many advantages over stamped ones. The most expensive discs - forged ones - were considered eternal, although they can be broken.

All modern rims are designed for tubeless wheels. In order not to violate the tightness of the tire, the edges of the disks must be even and have a perfect round shape. But it is the edges of the discs that are most susceptible to damage.

Wear due to frequent tire fitting

The cause of damage is the frequent re-beading of the wheels. Most of us do it twice a year, changing summer tires to winter tires and vice versa. Such a manner is most dangerous for stamped wheels - sooner or later tire fitting leads to paint peeling and rust on the edges. This leads to the fact that fully serviceable tires begin to etch the air. The first time after tire fitting, the sealant applied to the edge of the sidewalls of the tires saves, but over time it loses its properties, opening the way for air. The marker of such a malfunction is uneven descent of the wheel: the lower the tire pressure becomes, the slower it falls.

Finding the place to bleed the air is easy, but it requires you to remove the wheel and put it in water, or pour a little liquid around the rim of the wheel lying on its side and see where the bubbles form. And so on both sides. Subsequently, in places where air has passed, the surface should be restored by removing rust and updating the paint. You can do this yourself with sandpaper and paint sprayed from a spray can.

If I change wheels, do I need to balance them every season?

The correct solution is to have two sets of rims with two sets of tires. Such wheels are stored assembled and simply installed on the car without tire fitting, but with preliminary balancing, if necessary.

Effects of impacts

Another common but less common cause of depressurization is wheel rim deformation. Stamped discs are also more susceptible to this scourge. As a result of blows, their edges are crushed, opening the way for the air rushing out. Such damage can be obtained when driving at high speed through pits with vertical edges, places where asphalt is cut, when hitting curbs, and so on. In alloy wheels, with such impacts, the edges do not wrinkle, but break off, or cracks appear through which air will escape. It should be noted here that alloy wheels are much stronger than stamped ones and it is more difficult to damage them. Where the "stamping" will cover the edges, the alloy wheel will remain unharmed, but a lot depends on the rubber - low-profile tires protect the wheel from impacts worse. By the way, the high strength of alloy wheels often leads to serious damage to tires during impacts. Therefore, obstacles must be passed carefully, no matter what wheels your car has.

How to inflate a wheel without a pump? 5 myths and 2 risky ways

If cracks appear in the alloy wheel, it is better to get rid of it too. Most likely, you will be offered to weld a crack, but the temperature at which welding takes place will disrupt the structure of the alloy, making it less durable. It is no longer possible to rely entirely on such a disk. It is also useless to build up chips - the integrity of the structure cannot be achieved, which means that the repair should be considered nothing more than cosmetic. Such repairs are justified if you scratched or damaged the front side of the disk on the curb, which you unsuccessfully rubbed on when parking, or on another unnoticed obstacle. If at the same time the spoke was broken, then it is better to hand over the disc to the non-ferrous metal collection point and go in search of a new one.

A cast wheel, like a stamped one, can also be bought in a single copy. But keep in mind that regular "casting" and Chinese counterparts have significant differences, for example, in terms of weight, which is due to the use of a slightly different alloy. Therefore, the new disc should not only look like the rest, but also be released by the same company.

What happens if you put wheels with a long offset - do you know for sure?

Take care of the nipple!

Disc damage is not limited to dents, chips, cracks and warping. Each tubeless rim has a nipple that is easy to damage. This is not only about the spool, which can be tightened or replaced independently in three seconds and three kopecks, but also about the place where the nipple is attached to the disk.

Snow “behind the collar”

More often, winter drifters run the risk of encountering another problem - snow getting into the contact zone of the tire and disk, followed by depressurization of the wheel. When skidding, the tire is deformed with a drift to the side, and at this time a snowdrift collects in front of the wheel going sideways, the snow from which is stuffed into the gap formed. There, the snow thickens and becomes like ice. Subsequently, when side slip disappears, dense snow pushes through the rubber and opens the way for air. But this is not a problem of disks or tires, but of the driver.

Truck tires for semi-trailers

A truck tire is a complex technological product with a significant cost. The purchase of tires and their operation require considerable costs, so the choice of rubber must be approached very carefully.

There are 2 types of tires:

  • Radial
  • Diagonal

Bias tires and radial tires look very similar, but they are very different in design.

The carcass of a Bias Truck Tire is made from a multi-ply cord that acts as the skeleton of the tire. Cord threads of different layers are located at an angle of 35-40° to each other, that is, in a diagonal direction to the circumference of the truck tire.

In radial tires, the cords are tensioned at an angle of 90° to the tire circumference, that is, if you look at the truck tire from the side, the cords are located in the radial direction from the center of the tire circumference.

In addition to the arrangement of cords, there are several other differences:

  • Diagonal carcass cords are made of polymer materials (for example, nylon), while radial carcass cords are made of steel;
  • in diagonal tires, the carcass consists of many layers of cord, and in radial tires there is one layer of steel;
  • Bias tires have two bead rings, while radial tires have one;
  • basically, diagonal carcass tires are tubed, while radial tires are tubeless.

Each of these types of tires has its own advantages.

Radial:

  • better grip
  • lighter weight than diagonal tire
  • best load characteristics

Diagonal:

  • high strength
  • cheapness

Truck tire design

1 — Bead ring. It is the basis of any tire. In combination with the cord plies, it forms the tire carcass. The ring consists of a virtually non-stretch wire core. The bead ring provides reliable fastening of the tire on the rim, fixes its position and provides sealing.

2 - Ply(s) of carcass cord. They perceive all loads: static from the car and cargo, braking, traction and steering forces. Cord layers, interconnected by rubber layers, together with the bead rings form the tire carcass.

3 - Cord lapel. This is the part of the ply that goes under the bead and ends on the sidewall of the tire

4 - Chafer. This is a fabric or steel layer that covers and protects the cord lapel. Its main function is to eliminate wear and friction between the bead and rim of the disc.

5 - Shoulder protector. This is a special triangular rubber layer located in the shoulder area of ​​the tire that evens out the rounded shape of the carcass ply, making the tread area flatter. The undertread absorbs all the forces concentrated on the breaker edges.

6 — Breaker package (stiffening belt). It consists of several layers of steel cord placed between the carcass and tread of the tire, which encircle the latter along the entire circumference. Adjacent layers of cord in the breaker are located at an intersecting angle to each other.

The breaker provides tire strength, stiffens the tread, protects the carcass from damage, promotes efficient transmission of forces through the tread, and evenly distributes the load on the tire surface.

7 - Protector. This is the outer covering of a profiled rubber tire that is in direct contact with the road. The tread provides the necessary grip on the road surface. It protects the carcass from damage, ensures the operational life of the tire until it is restored.

8 - Undertread. This is the boundary layer of tread rubber between the tire tread and the protective layer of the breaker pack.
