✒️ Poem about the Autoreifen

Schwarz und rund, auf Asphalt und Grund,
Der Autoreifen dreht sich Stund um Stund.
Trägt die Last, bei Regen, Schnee und Hitze,
Sorgt für Halt in jeder Straßenspitze.
Mit gutem Profil, das ist sein Gebot,
Bringt er uns sicher, durch Fahrt und Not.

Black and round, on asphalt and ground,
The car tire turns hour by hour.
Carries the load, in rain, snow, and heat,
Ensures grip on every street's peak.
With good tread, that is its command,
It brings us safely through journey and demand.

❓ Riddle Time

Ich bin rund und schwarz, doch kein Planet,
Trage dein Auto, wohin es auch geht.
Ich brauche Luft, um richtig zu rollen,
Und gutes Profil, sonst kannst du's nicht tollen.
Man wechselt mich zweimal im Jahr zumeist,
Damit du sicher durch die Lande reist.

Wer bin ich?

I am round and black, but not a planet,
I carry your car, wherever it's sent.
I need air to roll just right,
And good tread, or driving's a fright.
I'm usually changed twice a year,
So you can travel safely, my dear.

What am I?
(Solution: Der Autoreifen / The car tire)

Word Composition

Trivia

• The term "Pneu" comes from French ("pneumatique") and refers to the air filling.
• The grooves in the tire tread (das Profil) are designed to channel water away and improve grip (protection against Aquaplaning/hydroplaning).
• The numbers and letters on the tire sidewall (die Reifenflanke) provide important information about size (die Größe), load capacity (die Tragfähigkeit), and speed rating (der Geschwindigkeitsindex).
