Probably one of the brands you have not heard of (I had not either), but 6.5 years and 30k miles ago, I put on a pair of these on the rear of my 3.0i E53:
Atturo AZ800 285/45R19 XL 111W BSW UTQG: 420AA. produced by Federal in Taiwan

No complaints at all. Good snow traction. Look like they will last to 60k miles if I let them go that far.
