Ever spotted the letters ‘MO’ printed on your tyre and wondered what they stand for? This guide explains the meaning of the MO marking, why it’s linked to Mercedes vehicles, and what benefits these specially designed tyres offer in terms of performance, handling, and safety.
If you look at the side profile of any tyre, you will notice countless markings, symbols, and abbreviations printed around the sidewall and outer edge of the tyre.
All of these have different meanings and are there to tell you, the driver, different things.
Some of them are easy to dissect and understand, whereas others are a bit more niche and unexpected. MO falls into the latter category.
But before we look at the meaning of an MO marking on a tyre, what are some of the more common symbols you might find printed on a tyre?
Common Tyre Markings
The sidewall of the tyre is where you will find the majority of markings, that denote and indicate the size of the tyre, its seasonal compatibility, its ideal pressure and weight rating, and more.
Some of the most common symbols and abbreviations to look for include:
- DOT – the date of manufacturing, as indicated by the year and which week of that year the tyre was made
- Tyre width and other measurements that link with the tyre size calculation
- A mountain range of icicle symbol that denotes the tyres are designed for winter use
- A/S or All-Season – indicating all-season tyres
- The brand name
But what does MO mean?
Understanding an MO Marking on a Tyre
MO is most closely linked to the brand name of a tyre, as it lets you know that the tyre is a ‘Mercedes Original’.
These tyres are found on Mercedes branded vehicles, with the manufacturer releasing its cars with specifically branded tyres fixed to them to optimise performance, safety, and comfort.
