I've got a 2018 X5M with 612M rims (21") and I've read/lurked through this thread more times than I care to admit. I've been rolling on the MPSS as I live outside of Charlotte, NC.

We built a home in Snowshoe, WV @ 3600Ft elevation 2.5 miles deep on gravel roads w/a VERY steep driveway. The MPSS would ensure I end up lodged in a tree recreating that ford explorer scene in Jurassic Park.

My conundrum: Charlotte is rarely below 40F so dedicated winters will melt. I feel like the poster boy of the mediocre All-Season tires + a set of Konig Summit XXL chains.

The 21" tire is a PITA to find AS tires for....

Question: Is there any preference between running 275/35/21 & 315/30/21 or square 295/35/21 setup on stock rims?
