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.

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.

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.
