Translation of nozzle in German

So we decided to move on. We were looking to get the next flight to Hoi Ann, which is located right in the center of the country, but we were told that there had been floods a week earlier.
On the first day in Hanoi, we wanted to explore the town. It was the former capital of the North and today it is the capital of the entire country. There are tons of monuments and governmental buildings.
We left town and drove around the lake. Around 30 minutes after leaving we had a flat tire, which I changed immediately. That was very annoying as the rental company asked us to fix the flat tire.
