What is Original Equipment (OE)?
Original Equipment (OE) tyres are developed in parallel with the vehicle itself. Continental invests hundreds of hours at test tracks and laboratories around the world until the tyre meets the car manufacturer’s strict standards. We’ve got a long history of OE success at Continental Tyres, as we’re trusted by leading vehicle manufacturers globally, to fine tune every detail to create a well-suited drive. It takes about four years from concept to production for one of our tyres to be fitted on a new international car model.
