About this generation
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.
Mercedes-Benz fits run-flat tyres on many C-Class models, paired with tyre pressure monitoring and no spare wheel. If your car was supplied with run-flats, replacements should typically also be run-flats.
Chassis code: W206. 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:
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.
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.

Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
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.
Where should I check the original tyre size for my Mercedes-Benz C-Class?
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.
The C-Class uses 19" or larger wheels — what should I know?
Larger wheels mean lower-profile tyres with shorter sidewalls — that means firmer ride, more pothole sensitivity and shorter tyre life on UK roads. Premium tyres usually repay the extra cost on cars with 19"+ wheels.
What does the chassis code W206 mean for tyre choice?
The W206 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 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.
