That time of year again. Got my first BMW (X4/F26) this year and since I travel a lot up to the Scottish mountains in the winter, winter tyres are a good investment. I had them on my last car and once you get them, you don't want to go back. I had Goodyear UltraGrip and they were excellent.
However looking at Winter Tyre options I have to say I feel a bit restricted. I'll need a spare set of wheels (ouch - recommended with RFTs) so been looking at the BMW options - but they only come with either Pirelli Sottozero II/Dunlop SP Winter Sport 3D - which to be honest are a bit "old" and don't fare well in the more recent reviews (although they are way better than summer tyres for winter driving) - both Pirelli and Dunlop have successor versions out, not sure why BMW is not selling the newer versions.
Continental 850Ps get the best reviews, with some of the Nokian tyres not far behind. The Conti's in particular as far as I can find don't have an RFT option (I'm on the fence with RFTs, I can see the advantage, esp from safety perspective for me driving in partic remote areas - but understand their negatives also). BUT - and it's a big BUT - getting hold of them for the X4 wheels is not straightforward (so much so I may end up getting them from BMW)
So 2 questions:
(1) Has anyone had the Pirelli Sottozero II/Dunlop SP Winter Sport 3D winter tyres and how were they?
(2) Has anyone used other winter tyres, which brand and how were they? (and where did you get them?!)
