Today’s word rolls in with more than one meaning. As a noun, Reifen means tire - like the ones on your car or bicycle. But as a verb, reifen also means to ripen or to mature. That makes it one of those handy German words with a literal and a metaphorical side. It’s one of the 1000 most frequently used nouns in German, too!
Let’s focus first on the noun: Reifen is a masculine noun, so the correct article is der - der Reifen. Still not sure about gender? Our super useful 5-minute video lesson will give you the shortcuts to figure out der / die / das confidently.
You’ll hear the noun Reifen in mechanical, transport, or safety contexts - garages, auto shops, bike repair, even toy cars. The verb reifen shows up in gardening, wine-making, and personal growth discussions.
- Dein Reifen ist platt.- Echt? Dann muss ich zur Werkstatt.(“Your tire is flat.” - “Really? Then I need to go to the shop.”)
Jonas: Mein Fahrrad ist kaputt.Mila: Was ist los?Jonas: Der Reifen hat ein Loch.Mila: Oh nein! Hast du Flickzeug?
(Jonas: My bike is broken.Mila: What’s wrong?Jonas: The tire has a hole.Mila: Oh no! Do you have a repair kit?)
Nominative: Der Reifen ist neu.(The tire is new.)
Accusative: Ich brauche einen neuen Reifen.(I need a new tire.)
Dative: Mit dem Reifen stimmt etwas nicht.(Something’s wrong with the tire.)
Genitive: Die Farbe des Reifens ist schwarz.(The color of the tire is black.)
Der Käse reift im Keller.(The cheese is aging in the cellar.)
Sie ist in den letzten Jahren sehr gereift.(She has matured a lot in recent years.)

Autoreifen - car tire
Fahrradreifen - bicycle tire
Winterreifen - winter tires
Ersatzreifen - spare tire
platter Reifen - flat tire
Reifen wechseln - to change tires
And as a verb:
reifen lassen - to let mature
zur Reife kommen - to come to maturity
eine reife Leistung - a mature or impressive performance
Despite the identical spelling, the noun Reifen and the verb reifen aren’t related: der Reifen originally meant a ring or hoop (you’ll still hear it for a hula hoop, der Hula-Hoop-Reifen), while reifen comes from reif (ripe).
Fun expressions:
„Ein platter Reifen.“ - a flat tire
„Reifeprüfung“ - final exam or “maturity test” (like the Abitur!)
„Reif für die Insel.“ - ready for a vacation or break (often said when exhausted)
