Quick answers about UK tyre fitment, MOT rules and seasonal options.
What tyre size does the 2018-present Mercedes-Benz CLS use?
Common UK factory fitments for the 2018-present Mercedes-Benz CLS include 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.
What does the chassis code C257 mean for tyre choice?
The C257 chassis code identifies this specific generation of the Mercedes-Benz CLS. 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 Mercedes-Benz CLS?
Typical UK tread life on the Mercedes-Benz CLS is around 20,000-40,000 miles depending on tyre brand, road conditions and driving style. Heavier trims tend to wear faster.
Did the 2018-present Mercedes-Benz CLS 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 wet grip should I look for on the Mercedes-Benz CLS?
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.
