Inflate the tires. Can an ordinary pump inflate it? How to inflate?

Yes, I always put a pump in my suitcase. Sometimes the tire pressure is insufficient, so use a pump to make up the tire pressure. Generally, 0.5 kg of pressure can be added under 20 or 30 strokes. Have you ever tried a friend saying that a pump can't inflate a tire? No practice, no right to speak! Don't pretend ignorance! !
