Hello,
I understand this tire comes as OEM on some MB EQ vehicles, curious how it compares/different to the 'non MO' version of the tire, tried searching but didn't find any information.


Thank you,

That information is classified but you could go through the tyre label of both and check load rating etc to see all relevant specifications match, however I have never heard of insurers requiring use of MO tyres therefore it is acceptable to use non-MO if tyre manufacturer approves use for your make and model though it is not recommended to mix MO and non-MO in same car!

MO means the tyre is approved by Mercedes for new vehicles, therefore the tyre will be Original Equipment. Mercedes MAY OR MAY NOT have changed the tyre slightly to their own specification, though changes are more likely for performance tyres I understand.

As tyres keep evolving I guess it may actually be better to use non-MO, the older the car! I hope to get the latest (presumably not MO'd for EQC) new-gen Scorpions next time as they are supposed to be much quieter, better braking etc:

Thank you,
Comparing the labels the MO version seem to have A for rolling resistance (vs C for the non MO version) and 70db for outside noise vs 72db for the 'normal' version. Both have A for wet grip.

Curiously the MO tire is rated W for speed rating and the Normal version is Y (270 Km/h vs 300 Km/h).

I'm using them on a KIA EV6 didn't like the Continentals that came with the car and always used Michelin in the past, again just curious. Any info is appreciated, thank you

The reduced rolling resistance is helpful to improve EQ range as electric cars usually have worse range than fossil fuel cars.

The lower noise is also useful in an EV because there is less engine noise to drown out tyre noise.

The lower speed rating is a compromise possibly to achieve the above but it's OK for UK as speed limits are under 270km/h and the already low EV range would plummet dramatically at those speeds anyway.

So you have a choice of initially cheaper(?) non-MO or quieter, more efficient, more Mercedes MO. I would choose the MO myself for the quietness and improved range unless there is some other tyre label difference that would swing in favor of non-MO. Just make sure the MO is ok by Michellin for EV6.

Thanks,
Notice that they are not EV tires per se - the Pilot Sport EV at teh same size are rated differently

Comparing EV and non-EV Pilot Sport tyre for EQC the tyre labels I checked seem identical though the "EV" version is newer (September 2021) and quieter so I would choose that if choosing between those two. There are other versions like Pilot Sport S that have shorter range for even better performance so you need choose what is most important to you
