I currently have an F90 M5 (obviously 4WD) with the 20" stock wheels/tires for summer (275 width fronts and 285 width rears). Michelin Pilot sport 4S.

I switch out the tires for winter tires of identical size every November-March. Pirelli Sotozero.

I live in a Lake Erie snowbelt region with flat terrain. Never have any problems in deep snow.

However, I plan to go with G80 6MT RWD for my next car. 19/20 wheel combination. Switch out the summers for winter tires, identical size for winter.

Very flat terrain here so I'll just take it easy in snowstorms, keep it in MDM for a little slip, and the engine in comfort mode.
