A car tire has blown out, making emergency braking impossible.

　　Even with properly rated tires, blowouts can still occur. If you’re unlucky enough to encounter low‑quality tires, or if you skimp on maintenance and keep driving with damaged tires, the risk of a blowout increases dramatically. When a blowout does happen, staying calm is the best way to stay safe—there’s no room for panic.

　　When driving at high speed, if the rear tire blows out, it’s relatively easy to control, though the vehicle will likely experience vertical vibrations. At this point, maintain firm control of the steering and work to bring the car to a safe stop gradually.

　　A blowout of the front tire is a leading cause of serious accidents. Not only does the vehicle shake and lean, but the steering wheel can suddenly be yanked sharply toward the side of the blown tire. At this moment, you must grip the steering wheel firmly and maintain control. Even a moment’s inattention can send the car spinning 360 degrees on the road.

　　It is important to note that the brakes play a decisive role in a vehicle’s performance. Under normal circumstances, when drivers encounter an emergency, their first instinct is to apply the brakes—this approach is generally appropriate.

　　However, if the front tire blows out, a single hard brake application can easily result in catastrophic damage and loss of life. Once the tire deflates, the interface between the tire and the wheel rim becomes extremely loose; the portion of the tire in contact with the road deforms and separates from the rim. Furthermore, when braking, the wheel on the punctured side—experiencing greater resistance—drops more rapidly, making it difficult to stop and potentially causing the rim to completely detach from the tire. Meanwhile, the opposite wheel struggles to apply equivalent braking force and may continue moving forward. It’s akin to a runner suddenly being forced to kneel on one leg, leading to the vehicle rolling over.

　　Therefore, when the front tire blows out, you can only rely on the engine’s traction to slow down. For manual‑transmission vehicles, shift directly from fifth or fourth gear into the next lower gear, then continue downshifting gradually until you reach first gear. Drivers of automatic‑transmission cars often forget about the gear selector; in such cases, they can also engage a lower gear to reduce speed. Once your speed is under control, gently apply the brakes to bring the vehicle to a complete stop.
