[* black] Acknowledge that you have a flat tire.
+[* black] A flat tire means deflated even without rider on the bike. If the tire is flat as soon as you get on it, it's not properly inflated. In general, the pression should be at the maximum (less wear, less risk of puncture, more speed, less efforts).
