About this generation
The current-generation Mercedes-Benz C-Class (2014-2021) 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.
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.
Chassis code: W205. Use the chassis code to confirm you have the right generation when ordering tyres.
Common factory tyre sizes

Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What tyre size does the 2014-2021 Mercedes-Benz C-Class use?
Common UK factory fitments for the 2014-2021 Mercedes-Benz C-Class include 205/60 R16, 225/50 R17, 225/45 R18, 225/40 R19. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
Did the 2014-2021 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.
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.
Can I downsize from larger wheels on my Mercedes-Benz C-Class?
Some trims of the C-Class can be downsized to a smaller OEM-approved wheel, which often gives better ride and lower tyre cost. Mercedes-Benz usually publishes approved alternative sizes — check the handbook before changing wheel size.
What wet grip should I look for on the Mercedes-Benz C-Class?
For UK driving conditions, prioritise an EU tyre label wet-grip rating of A or B. Wet grip directly affects braking distance — the gap between A and E ratings can be more than a car length at 50 mph.
