How should I choose winter tires for a Mercedes-Benz E450 AT when the CoC lists 255/45 R19 104Y?

Hello, I would start with the complete tire-and-wheel combination in your vehicle’s CoC, including any axle-specific entries and remarks, before choosing a winter tire. The CoC is specific to the individual vehicle. In 104Y, 104 is the load index and Y is the speed rating. I would retain the specified load capacity and ask Mercedes-Benz to confirm the winter tire speed-rating requirements before choosing an alternative with a lower speed rating. For winter use, look for the three-peak mountain snowflake symbol (3PMSF), which indicates verified snow performance. Please share the model year and the relevant CoC tire entries, with personal information removed, so the next step can address your vehicle’s exact specification.
