Mercedes-Benz CLS tire size
Original tire sizes for the Mercedes-Benz CLS, model years 2019, 2020, 2021, 2022 and 2023. Trim levels and wheel packages change the size within the same year, so confirm on the door-jamb sticker before ordering.
Check before you order. The surest answer is the tires on the car right now: the size is molded into the sidewall. The placard inside the driver's door tells you what the factory fitted, which can differ from what a previous owner put on. Our guide on reading a tire size shows exactly where to look.

What Mercedes-Benz approves
MO is the Mercedes approval, MOE is the run-flat version and MO1 is reserved for AMG models.
Mercedes tunes the tire to the car's suspension and electronic aids, so an MO tire on a Mercedes usually rides closer to how the car left the factory. MOE tires have a reinforced sidewall and only belong on a car built for them.
Brands that carry the approval
Written on the sidewall as: Continental ProContact (MO), Michelin Pilot Sport 4 (MO1).
The drawing carries the sizes we list for this car, so you know what you are looking for. The placard on the car is still the final word, and it is the only place that gives the cold pressures: the number molded into the sidewall is the maximum the tire can hold, not what your car wants.
What those tires cost
Buying wheels at the same time?
A staggered car is the one case where new wheels and new tires usually happen together, because a bent or corroded rear rim is what sends most people shopping in the first place. Four numbers have to match before the size does any good.
- Bolt pattern
- Number of studs and the circle they sit on, written as 5x114.3. It is not adjustable; adapters are a compromise.
- Offset
- How far the mounting face sits from the centre line. Wrong offset rubs the strut or the fender, even in the right size.
- Centre bore
- The hole in the middle must sit on the hub, not on the bolts. A hub-centric ring fills a bore that is too large.
- Load rating
- Each wheel must carry its share of the loaded car. This is what gets missed on trucks and on anything towing.
