Michelin Primacy Alpin PA3 225/45R17 91H
Michelin X-Ice Xi2 225/45R17 94T
now only two chices .which one better for 4WD car and break at ice and snow exetl.
While I haven't tried the X-ice Xi2 Based on the reviews I've read I would go with them if I expected to have mostly icy conditions, but would go with the PA3's if I was expecting more snow and slush then straight icy conditions. 4WD is pretty much irrelevant as all cars use all 4 tires to turn and brake.
I would say at this point buy either one before you're unable to get either. Trust me even a less then cheap snow tire is substantially better then a great all season tire, when its -10 with a half inch of snow on the road. At this point you need to make a choice while you still have one and either will be a lot safer then any all seasons you may have.
