I understand that the maximum speed is lower ... i doubt i'll be hitting that in winter. But there is an 1100lb difference in load capacity. that said, I don't know if it is as simple as adding it all up at each tire.
for the square 101W it looks to be about 7300lb and for the 105Y/107Y it is 8400lb.
either way, it is far above the gross weight limit of the m5 at 5400lb.

Agreed, with Miko.
Don't forget always engineers with everything in life over estimate.
I myself do the same.
so that typically means all calculations are X 3.
