I've complained about the Bridgestones before, mainly because of early wear and noise. But I will say they do fine in snow -- not as good as a snow tire, but fine in Minnesota winters for me.

My issue with them in the winter is noise and the harsh ride. The colder it is, the louder sounds are (hence the tires make seem louder). Also our roads tend to get bumpier during the winter from frost expansion and those little bumps can be brutal with the Bridgestones.

I have had non-RFTs on my previous E53 (I have an E70 now) and I agree with other posters, the non-RFT road smoother but turn in was a little looser. That said, I prefer the non-RFT ride and will be switching soon as my Bridgestones start to get louder.
