18" aero wheel 750kg load rating and part numbers

[chasemarmot]

Does anyone know how to tell if an 18" aero wheel is rated for 700kg or 750kg other than a stamp on the wheel? Perhaps using part number?

I'm trying to order a set online my LR MY to mount winter tires and am finding it difficult to confirm the load rating prior to ordering. I'm finding several part numbers:

104422100B
104422100A

104426100A

Does anyone know if one these corresponds to the newer 750kg load rating?

Another post shows the 104426100A as having the 750 load rating. Not sure if that's across the board, but it's a data point.

Hi All,

The wheels on my 2020M3LR are part number 104422100C (standard 18" Aero).
I'm buying second hand wheels to put together a winter set.
Does anyone know what the difference is between the part numbers?
There is a set of 104426100A going that look the same.
Is there any variation in colour or size?
I will probably get them all refurbished so less fussed about minor colour variations.
