Surviving gunshots to the tires: why run-flat systems matter

In a dangerous situation, mobility is your best defense. If a vehicle can no longer move, it becomes a stationary target. That's why one of the most critical components of vehicle armor is not just the steel or the glass, but what's inside the tires.

What Is a Run-Flat Device?

A run-flat is a high-strength polymer or rubber ring installed inside the tire, hugging the wheel. Its main function is to carry the vehicle's weight and let it keep rolling even when the tire has lost all air pressure from gunshots or spikes.

Armored Vehicle Tires: How Do They Work?

It's important to clarify one point: the tire's rubber is not “bulletproof” by itself. What really defines armored vehicle tires is the internal system that keeps the driver in control after the tires take bullet hits.

When projectiles go through the tire, the run-flat device keeps the wheel from touching the ground and the tire from coming off. This lets the vehicle keep moving steadily, so the driver isn't trapped in the danger zone.

For Emergency Use Only

A common mistake is thinking a vehicle with run-flats can be driven normally after an incident. It's vital to understand the following:

• They are not for long distances: The system is designed specifically to escape an attack and get to safety.
• Limited capacity: They usually allow you to drive between 20 and 50 kilometers (12 to 30 miles) at moderate speed (80 km/h or 50 mph at most), depending on the model and weight of the vehicle.
• Immediate replacement: Once a run-flat has been used in an emergency, the system and the tire must be inspected and, in most cases, replaced by professionals.

Mobility Is Survival

At RGM Advanced, we know that in an attack every second counts. Having an emergency run-flat system is not a luxury; it's the guarantee that you'll be able to get out of “ground zero” and find safety.
