Performance tires and snow, even light snow dont mix.
I wrecked one of the nicest early Q45's in the country, drivign in very light snow, very carefully at 48 mph on the interstate (=spin+ bouncing off guardrails)..
If you are enetering the winter in Michigan and you stoill want some poor weatehr ability Michelin pilot XGTH's in All season.
Or any hi end all season tires.
The Michelins I put up tehre are only slughtly better than teh Sports or otehr performance tires in poor weather .
In Michigan winter I would throw on dedicated winter tires from december thru late feb. rest of teh year performance tires.
