Can I patch a run-flat tire the next day if it's leaking?

It is acceptable to patch a run-flat tire the next day if it's slowly leaking, but if the leak is rapid, you should promptly replace it with a spare tire. The method for repairing a run-flat tire involves using a mushroom plug, which is a rubber patch shaped like a mushroom. The process involves locating the puncture from inside the tire, pushing the stem of the mushroom plug through the hole, trimming the exposed part outside, and securing the inner part with specialized adhesive. The stem of the mushroom plug provides an external repair effect, while the inner part functions as an internal repair. The technical name for a run-flat tire is 'tire pressure monitoring system (TPMS) tire.' When inflated, the sidewall of the tire bears the main load of the vehicle's weight. It consists of the outer tire, standard inner tube, spare inner tube, steel rim, gas generator (or air reservoir), pressure sensor, and control unit.
