Yup, those are the codes - What do they all mean?

Don

It means this

Since EV tires are designed & constructed differently than ICE tires, when the tire needs to be replaced, it should be replaced with tires with the same code.
You can use EV tires from different code but has to be installed as a pair on the same axle.

It started out with tires meeting the official Audi spec being stamped “AO” for “Audi Original”, and Mercedes “MO” for “Mercedes Original“. It has all gotten a little silly from there. Usually so long as a tire has the same spec (size and load rating) it is identical and you can ignore the stamp.

This is from the Pirelli Tyres website as to why of the "Custom-Tyre Marking" whom they started with Porsche in 1980.

As a designer/engineer, probably I'm a sucker, but I've always been a believer in the OE or OEM, not Aftermarket products. It's not a farse by any stretch of any imagination.
Take it any which way you want it.

The same is true for EVs to an extent. The spec will have an unusually high load rating and this is much more critical than an ICEV (an ICE wagon will require a high load-rated tire in case it is fully loaded whereas a BEV is always heavy). The main feature of an EV rated tire is that it will be much quieter because tire noise is much more noticeable in an EV.

There's a lot of engineering that goes behind designing EV tires.

That tire appears to be from December 2020 (5020 date code). But TireRack says that there is a new European tire labeling standard that went into effect in May 2021. I would be curious to see if cars shipped to the US are coming with tires marked according to these new standards.

That's correct. Tires coming to the US will have only DOT label & certification. That certification is only for EC.
