Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
Are OEM tyres still fitted to new Audi A6 cars?
New UK Audi A6 cars leave the factory with original-equipment (OEM) tyres specified by Audi. When replacing, you can stay on the same OEM brand or move to an alternative provided the size, load index and speed rating match.
What tyre size does the 2018-present Audi A6 use?
Common UK factory fitments for the 2018-present Audi A6 include 225/55 R17, 245/45 R18, 255/40 R19, 255/35 R20. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
Where should I check the original tyre size for my Audi A6?
Look in three places: (1) the sidewall of the existing tyre, (2) the placard inside the driver's door frame, and (3) the vehicle handbook. The driver's door placard is the official OEM specification, and the sidewall confirms what's fitted now.
What does the chassis code C8 mean for tyre choice?
The C8 chassis code identifies this specific generation of the Audi A6. Tyre fitment guides and parts catalogues use the chassis code to match correct sizes, load indices and speed ratings — useful when ordering online.
How long should tyres last on the 2018-present Audi A6?
Typical UK tread life on the Audi A6 is around 20,000-40,000 miles depending on tyre brand, road conditions and driving style. Heavier trims tend to wear faster.
