Winter complete wheels Spacetourer, aluminium wheels, COC

We want to buy our new Spacetourer winter tyres. As complete wheels for me aluminium rims. My problem: if I search in the various online shops for complete wheels for the Spacetourer I get (depending on the shop) different rims offered. However, all do not fit from the combination of the information to those in the COC. There is required: 7.00×16 ET46 Or 7.00×17 ET46 I have already found some with 7.00, but with a press-in depth of 37, instead of 46. Does someone have a tip where there is such a thing? And why do the tyre shops suggest other rims, although I have selected the Spacetourer as model? Thank you.
