Usage tips
Compound word
The word is simply made up of 'Winter' (winter) and 'Reifen' (tire). So it is literally a tire for winter.
EXAMPLE
Neue Winterreifen können die Sicherheit bei Schnee und Eis deutlich erhöhen.
New winter tires can significantly increase safety in snow and ice.
Typical verbs
In connection with winter tires, specific verbs are used. In the fall, you have the tires 'aufziehen' (put on) or 'montieren' (mounted), and in the spring you 'wechseln' (change) them again.
EXAMPLE
Ich muss dringend einen Termin machen, um die Winterreifen aufziehen zu lassen.
I urgently need to make an appointment to have the winter tires put on.
Cultural context
In Germany, there is a well-known rule of thumb for winter tires: 'von O bis O' (from O to O). This means you should have them on the car from October to Easter. This is not a law, but it is a widely followed recommendation.
EXAMPLE
Mein Vater erinnert mich jeden Herbst an die „O-bis-O“-Regel für Winterreifen.
My father reminds me every fall of the 'O-to-O' rule for winter tires.
