DriveHard -- I appreciate the insight regarding the square setup.
Cool, I guess that solves that pretty much... not that there is anything wrong with her tires, but she is getting less than optimal performance due to them being aggressively snow-centric rather than having a good balance between asphalt and snow.

Well, I bought the Goodyear Eagle UG-GW3 RSC wheel and tire package that BMW sells up here in Canada, and I can say that with these tires I'm experiencing the same issues that you are (my car is a 2011 135i), hitting WOT at 60 mph (100 kph) has broken grip on these tires in above-freezing temperatures; not a good sign.
It's also extremely easy to break the back-end free during cornering and as I found out recently, these will lock-up at low speed with hard breaking on dry pavement (above freezing again).
I'm actually pretty pissed that BMW sells such a limited selection of winter tires and the one that they sell for my car removes all of the active safety features the BMW 135i offers (great breaking, acceleration and agility).
