That’s a good question Tony. We have a set of Pirelli Sottozero’s for Gail’s car on 17”s. They are 45% profiles and the offset is only 30 on those wheels. Neither is a good fit for the 330e that has 37 offset and needs 50% profile although the offset could be sorted with spacers. So, I’m looking for winters too.
Auto express have a review of winters here -

The Continental TS860 comes out overall winner but the Hankook i*cept RS2 was a close second. However, you have to look closely at where they performed. The Hankook was a clear winner on snow and the Continental much better in the wet. The latter probable suits the majority of winter conditions that most of us face on a day to day basis.
What isn’t so clear is the performance on ice. We (in the soft south) get far more icy roads generally than we do snow.
This is especially true off main roads and out in the sticks where gritters don’t get until the major routes are clear.
I would prioritise performance on ice above that on snow. If you know you’re going to get snow then the Hankooks, but, would they be better on ice too? With rear wheel drive that’s a key indicator but this review doesn’t give any clues.
