Winter tyres and rims for MB EQE SUV (x294)

Hello together, I’m looking for winter tyres and matching 19-inch rims for my EQE SUV. Unfortunately, I don’t really like the rims offered by Mercedes-Benz, and since the model is still relatively new, there is very little choice on the market. I have contacted several sellers of rims that offer rims with ET values from ET30 to ET45 with TÜV. However, I thought that the ET value should not differ by more than +/- 5 mm from the permissible value. On eBay gi bt it also original Mercedes rims in size 8J x 19 ET38. Wouldn’t that be closer? But should these rims probably be entered in the vehicle papers? MfG
