When a tire blows out, quickly shifting from a higher gear to a lower gear to utilize engine braking for descending slopes is referred to as downshifting during a tire blowout for deceleration. Below is additional information: 1. Principle of downshifting: Forced downshifting, also known as emergency downshifting. The principle involves using engine braking to decelerate, typically employed when the brakes fail or a brake wheel malfunctions. This means entering a gear that is not suitable for the current speed, such as attempting to shift into 3rd or even 2nd gear at 80 km/h, which requires a double-clutching operation and revving the engine in neutral to facilitate smooth gear engagement. 2. Vehicle tire blowout: The vehicle will immediately veer or sway severely. You should firmly grip the steering wheel with both hands, release the accelerator pedal, and allow the car to continue moving in its original direction until it comes to a stop on its own.
