About this generation

This generation of the C-Class runs on 19-inch or larger wheels in some trims, which means short-sidewall tyres that handle precisely but are less forgiving on rough UK roads.

The current-generation Mercedes-Benz C-Class (2021-present) is sold in the UK with a small set of factory tyre sizes per trim. Replacement tyres should match the size, load index and speed rating of what came on your specific car.

Chassis code: S206. Use the chassis code to confirm you have the right generation when ordering tyres.

Common factory tyre sizes

UK-market factory fitments for the 2021-present Mercedes-Benz C-Class typically include:

Mercedes-Benz works with tyre makers to develop OEM-marked versions for the C-Class, tuned for the car's suspension calibration. Star, MO, AO or J markings indicate manufacturer-approved tyres.

Wet grip is the most relevant EU label rating for UK driving. On the C-Class, prioritise wet grip A or B for shorter braking in rain.

Frequently asked questions

Quick answers about UK tyre fitment, MOT rules and seasonal options.

  • Did the 2021-present Mercedes-Benz C-Class come with run-flat tyres?

    Many Mercedes-Benz models in this era were supplied with run-flat tyres from the factory. If your car has tyre pressure monitoring and no spare wheel, replacement tyres should typically also be run-flat. Verify on the existing sidewall — look for "RFT", "ROF", "ZP" or similar markings.

  • What tyre size does the 2021-present Mercedes-Benz C-Class use?

    Common UK factory fitments for the 2021-present Mercedes-Benz C-Class include 225/50 R17, 225/45 R18, 225/40 R19, 255/35 R19. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.

  • What should Mercedes-Benz C-Class drivers know about UK potholes?

    UK road conditions are tough on tyres. Check sidewall bulges, cuts and tread depth regularly — especially on the inside edge, which often wears unevenly. A 20p coin gives a quick legal-tread check.

  • What does the chassis code S206 mean for tyre choice?

    The S206 chassis code identifies this specific generation of the Mercedes-Benz C-Class. Tyre fitment guides and parts catalogues use the chassis code to match correct sizes, load indices and speed ratings — useful when ordering online.

  • What do star/OEM markings mean on Mercedes-Benz C-Class tyres?

    Mercedes-Benz approves specific tyres for many of its models, marked with a star (BMW), MO (Mercedes), AO (Audi), J (Jaguar) or similar. OEM-marked tyres are tuned for that car's suspension and don't always come from the major brand-name fitter as a stock item — they may need to be ordered.
