I live in Maryland and my FR-S that is lowered (1.4" Eibach) and on snow tires (Blizzak WS70 215 R17) continues to sit in my driveway because I can't back out. I don't even see snow under my tire. I mean look, you can even see the rocks where the tire dug in so its obviously contacting my driveway. my driveway is flat by the way. I am absolutely baffled at how others are able to drive in the snow. I wasted a lot of money on tires and rims. Thinking about trading the snow tires in for R compound for HPDE if I can find someone to do it. As far as ride height, I can't help you because ride height is not the problem, its traction. I purchased my parents 2009 4Runner before winter and its an absolute beast. That 9" we just had? No problem.
It just occurred to me that I would have more traction pushing the car.... -_-
