Find Tyres for 2019-present Mercedes-Benz CLA (X118)
Find the right tyre size for the 2019-present Mercedes-Benz CLA — match against your sidewall before booking a fit.
About this generation
This generation of the CLA 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 CLA (2019-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: X118. Use the chassis code to confirm you have the right generation when ordering tyres.

Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What wet grip should I look for on the Mercedes-Benz CLA?
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.
Is the Mercedes-Benz CLA still on sale in the UK?
As of the 2019-present window, the Mercedes-Benz CLA is currently on sale in the UK. Tyre fitments listed here reflect UK-market specifications.
Are premium-brand tyres worth it on a Mercedes-Benz CLA?
On a Mercedes-Benz CLA, premium tyre brands (Michelin, Continental, Bridgestone, Pirelli, Goodyear) typically deliver longer tread life, better wet grip and quieter rolling. The cost difference is usually recouped over the tyre's life.
Where should I check the original tyre size for my Mercedes-Benz CLA?
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.
Did the 2019-present Mercedes-Benz CLA 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.
