Only Bridgstone Blizzaks are approved. They are real wintertires. Would have been handy last week but so much snowquite rare. I ordered from Tire Rack Dunlop all season tires but will get them only end february sadly. The Enkei wheels were not on stock. I think the Dunlop all season tires are approved in USA too.
Winter tyres do not help with aquaplanning, actually they can be worse int hat respect. They do help in snow, mud, and all kinds of stuff you see in winter. They are far too wide to give any decent performance in snow, but the car is drivable. (I am talking from a perspective of a country with heavy snowfalls - ~20cm yesterday and constantly below -5 degrees).
