Just wondering. Are your winter tires 18", 19" or 20"?

I used to have fantastic grip with my 18" winter tires --- haven't fully tested my current 20" winters yet...

And to answer one of your questions. I have read that 62% of the power is supplied to the rear wheels. Another source said 68% so not sure which number is correct.
