What is Our Innovation in Run-Flat Tire Changers

In the demanding world of military vehicle maintenance, GM Defensive stands out with our innovative run-flat tire changers. Our machines are not only designed for efficiency but also prioritize operator safety through advanced features and technology. Let’s delve into what sets our run-flat tire changers apart and how we ensure the highest standards of safety and performance.

What Makes GM Defensive’s Run-Flat Tire Changer Unique

At GM Defensive, we understand the critical nature of military operations and the importance of reliable equipment. Our run-flat tire changer is engineered to meet these demands, offering unique features that enhance safety and operational efficiency.

Advanced Safety Features

1- Securing Mounting and Dismounting Processes

Safety Shield

Design and Material

Our safety shield is crafted from durable materials designed to withstand the rigors of heavy-duty tire changing. This shield is crucial in protecting operators from potential hazards during the tire-changing process.


The safety shield not only protects but also secures the run-flat tire, ensuring it stays in place due to its weight and design. This prevents any accidental dislodging during the operation.

Chain Mechanism

Enhancing Protection with Secure Safety Shields

We use a robust chain mechanism to secure the tire during mounting and dismounting. This system ensures that the tire is firmly in place, minimizing the risk of injury.

2- Run-Flat Shields

Unlike other products on the market, our run-flat shields have an opening capacity of 1 meter (100 cm). Most other products typically open up to 80 cm.

The reason GM’s shields are designed to open up to 100 cm is to handle larger run-flat tires. The segmented, polygonal design of our run-flat shields ensures that even large run-flat tires can be changed safely and securely.

Segmented Design

The run-flat shields are maintained at an angle in segments (polygonal rather than round) to prevent slippage. This design is crucial because compressed run-flat tires contain significant energy and can try to escape if not properly secured.

Watch our demonstration video to see how the segmented design enhances safety in our run-flat tire changer.

Handling Capacity for Run-Flat Sizes

GM Defensive’s run-flat changer machines feature run-flat shields that open up to 100 cm. This capacity ensures that vehicles with larger run-flat tires achieve maximum performance with our machines.

Prevention of Run-Flat Slippage

Our wide run-flat shield design accommodates larger run-flats and prevents them from slipping and throwing out, ensuring a safe and controlled tire change.

3- Split Rim Wheel Replacement

Security Table Design

4- Grease Oil Use

Grease Pump and Grease Gun Option

Enhances user flexibility and boosts productivity

In case of customers requesting, we provide a grease pump or grease gun, along with a compressor, to safely apply grease oil to the inner parts of the run-flat tire changers. This system allows operators to grease the shield without putting their hands inside, significantly reducing the risk of injury.

Using the grease pump or gun minimizes the risk of injury and ensures that the run-flat tire changers operate efficiently without the need for manual application of grease. This not only improves safety but also enhances the overall maintenance process.

5- Emergency Stop Features and Controllers

Remote Controls

Radio Remote Controls

Our machines come equipped with two radio remote controls, each featuring an emergency stop button. These controls allow two operators to work independently, managing all machine functions from a distance of up to 50 meters.

The remote control can operate up to 50 meters. It is equipped with an emergency stop button, allowing the operator to stop the machine from a distance of up to 50 meters in case of an emergency.

Handheld Controllers

We also provide one handheld controllers, each equipped with an emergency button. These controllers are specifically designed to operate the winch and hydraulic piston, enhancing safety during the tire-changing process.

Emergency Button on Electrical Panel

An additional emergency button is located on the electrical panel, ensuring that operators can quickly stop the machine in case of an emergency.

Joystick Control

The Workshop model is equipped with 4 emergency stop buttons. The Double Workshop model features 6 emergency stop buttons. Both the Container model and the Trailer model each have 4 emergency stop buttons.

The joystick control, which has an emergency stop button, manages hydraulic pistons. This comprehensive control system ensures that operators can handle all machine functions safely.
