Tire Blowout

Hold the steering wheel firmly with both hands — a blowout creates an immediate pull toward the affected side. Do not slam the brakes. Keep your foot on the accelerator briefly to maintain momentum and stabilize the vehicle, then ease off gradually. Look ahead toward the shoulder and steer there progressively as speed drops. Apply gentle braking only once the vehicle is traveling slowly and tracking straight. Activate hazard lights.

Hard braking during a blowout can cause the vehicle to spin or veer sharply out of control. The blowout has already upset the balance of forces acting on the vehicle. Adding sudden, heavy braking — particularly if the damaged tire locks — multiplies the instability. Allowing speed to reduce naturally through reduced throttle and the drag of the flat tire gives you more time to steer and stabilize before braking gently.

A blowout is sudden and dramatic — a loud bang or explosive sound, an immediate strong pull to one side, and vibration through the vehicle. A slow flat develops gradually: subtle handling changes, the vehicle drifting slightly, and increasing vibration as the tire deflates. TPMS helps identify both, but a blowout is felt instantly through the wheel and body of the vehicle, while a slow flat may only trigger the TPMS light after some time.

The most common causes are sustained underinflation (which causes the tire to overheat and fail structurally), overloading the vehicle beyond tire and vehicle ratings, impact damage from potholes or road hazards, and driving on a tire with pre-existing damage. Regular pressure checks, staying within load limits, avoiding road hazards where possible, and having tires professionally inspected after hard impacts all reduce blowout risk significantly.

Often not. A blowout involves structural failure of the tire — broken cords, severe sidewall damage, or carcass failure — rather than a simple puncture. Even if the damage appears localized, the tire must be removed from the wheel and inspected by a professional before any decision is made. Running a tire flat even for a short distance typically causes damage beyond repair. In most blowout cases, replacement is necessary.

Run-flat tires are designed with reinforced sidewalls that support the vehicle's weight after pressure is lost, allowing limited driving to a service location. In a pressure loss event — which may be more gradual than a traditional blowout — a run-flat allows the driver to maintain control and reach safety without needing to change the tire immediately. The vehicle's TPMS is essential with run-flats, as the tire looks and feels nearly normal even when deflated.
