Good choice!
but let me continue my deep analysis since Im on the roll here lolz
but overall using the same charts
http://www.tirerack.com/tires/survey...port%20Package
SP Winter Sport beats Blizzak and Alpin
however
SP Winter Sport 3D loses on Heavy Snow Traction over Blizzak, but SP
Winter Sport M3 does not
and
SP Winter Sport 3D wins over ride and noise comfort against the 2, but the
SP Winter Sport M3 loses to Alpins in ride and noise comfort
amazing analysis
thats why if I ever get a trade in deal on my e90 for a smaller commuter car, its Winter Pilot Alpin new owner will be happy with his new winter set
but of crse A/S tires are another debate with it own merits
