Zero tire pressure continuation means that in the absence of air, the tires can continue to drive at a distance of about 80 kilometers, so as to ensure that the car can safely reach the maintenance site. It's not high tech, it's a blast tire. You must know that a run-flat tire is not a "explosion-proof", but a "warranty tire with insufficient air", which is a support structure added to the sidewall of the tire, which can provide sufficient support in the absence of air.
