Once the tyres meet the requirements of the vehicle manufacturer, some apply a specific designation showing that the tyre is approved and developed specifically for their vehicles.
Continental offers an extensive range of original equipment tyres. OE keys on the sidewalls show which brand and model an OE tyre has been made for. But even if no marking is visible, you can be reassured that the tyre is particularly manufactured for the specific car brand. The table below provides an overview of existing OE keys.
