Winter Tires on 666 Wheels

[instarand]

I'm looking to put winter tires on my 666 wheels. I don't want to reduce wheel size which I realize gives me more options. I seem to have found the following:

Michelin Pilot Alpin PA4
Front: 245/35/20
Rear: 275/30/20

And

Pirelli Sotozero 3
245/30/20
265/30/20

I reached out to my local bmw dealer and I was told bmw has not "approved" any winter tires for the 666 wheels. However, his recommendation was to find front tire size and put them on all 4. Such as a Continental Contact TS830P that come in 265/30/20 (same size as factory fronts)

Are all of these viable options? Any recommendations or experiences here? Thanks everybody!

Just to chime in....

20" wheels are a chitty setup for the winter

But/and you could put some conti DWS all seasons on.
