If a tyre on the rear axle blows out while you are driving, it is important to **brake firmly** to maintain control of the vehicle. Here we explain why:

- **Vehicle control:** When a rear tyre blows out, the vehicle can become unstable and difficult to handle. Braking firmly helps reduce speed in a controlled way, avoiding abrupt movements that could further destabilise the vehicle.

- **Active safety:** The vehicle’s active safety systems are designed to help you keep control in emergency situations. Braking firmly is an action that allows these systems to work effectively, helping to bring the vehicle to a safe stop.

- **Avoiding dangerous manoeuvres:** Steering sharply or continuing to drive with a blown tyre can be very dangerous. These actions can cause the vehicle to lose traction or deviate from its path, increasing the risk of an accident.

Therefore, in the event of a rear tyre blowout, the safest course of action is to brake firmly to stop the vehicle in a controlled and safe manner.
