Best Tyres for the BMW M550d xDrive

Bought after reading reviews, seemed like a good bang for a buck and not disappointed.
They seem narrow for a 245, which probably affects rolling resistance and aquaplaning properties positively. Pretty low cabin noise. I haven't been driving on the edge, but even with more spirited driving, I couldn't get them to slip. I'm mostly just cruising on country roads and I can not exceed their potential. On wet motorway they perform well and aquaplaning resistance is good. Wear seems OK. Steering feedback is fairly good, but the car being a 5 series with AWD, I expect some numbness from the car as well. Tread depth when new isn't much with 7.1 mm, I am yet to measure how I did this summer as I just switched back to winter tyres.

I bought these in the end of spring to use only in winter. Generally they are very good. Having driven only studded winter tyres, I find them much better in the wet and dry. On snow they are exceptional and on ice surprisingly good - given my previous experience with mid to top tier studded alternatives, these frictions truly stand up on ice. They lack a little bit of feel on straights, giving a noticeable gap in steering response, but I'd say this is common on most winter tyres. Handling is good and they are quite predictable even on ice. After the first winter of 16000 km, they seem to hold up fine and I can probably get at least 2 more winters out of them. In my opinion cabin noise is very low and they are truly comfortable as well.
I always hesitated on buying non-studded winter tyres, reason being occasional extreme road conditions, but these exceeded my expectations and I'm happy with them.
