Overall I am happy with my winter tires, this is the second winter that I've had them on the car and boxing day was the first day I have driven in snow and I am very glad to say they were excellent.
Previously my 5 series would get stuck on level ground in the snow and I struggled to get it moving even with a push, but now there is no stopping it, the new worry is the car behind that probably doesn't have the ability to stop as quick as me.
I run Michelin PS2 in summer and that is the best tyre I have had, so the Yokahama W - drive has a lot to keep up with and if I'm honest the grip level reduction in dry weather was noticeable with the Yoko's. In slightly damp weather my traction control light comes on quite often, but in the same conditions the PS2'S wouldn't lose any traction at all (even at the same temperature).
In cold conditions below 7c I feel more confident with the wDrives, I've lost traction a few times on roundabouts but I was pushing it and they were progressive and I maintained control.
The main reason I got these was the brand name and previous glowing reviews on here and a good price for tyres and alloy package but in hindsight I wish I had gone for the Nokians, Michelin Alpine or Continental TS850s
In total I paid £1500 for the alloys and tyres 245 40 18 run flats.
