245/35/20=26.8"
275/30/20=26.5"

difference is 0.97%=1% ok for x-drive. diametrically, 235/35/20 up front would pair up better with a 275/30/20 rear if x-drive.

fwiw, those rims are 15.6kg=34.3lbs each. with larger diameter(taller gearing), wider(more rolling resistance) and heavier tires you should expect to feel a significant difference in acceleration/braking. not that you're accelerating or braking hard in the winter...just sayin'
