I just bought a set of Pirelli Scorpion 19" winter tires. No runflat (I will never buy that stupid rip off thing), just the good old technology (=repairable at low cost in any workshop in case of nail puncture).

I am not a fan of Pirelli but this one is really as good as the reviews said. Much smoother ride vs the Conti summer runflat my X5 came with.

Good grip, the other day the road was pretty icy and all the cars were quite slow. I took over a couple of them with much confidence.
