In the event of a tire blowout, the most crucial action is to grip the steering wheel firmly and gently ease off the accelerator. This method allows you to maintain control of the vehicle without making abrupt movements that could cause loss of control. Sudden braking or harsh steering can lead to further instability, potentially causing the vehicle to skid or veer off the road. Gradually slowing down and steering firmly ensures a safer management of the vehicle until it can be brought to a controlled stop.
