if they are mounted on their own rims for 2019 xdrive40i? I believe the OEM size is 265-50-19

these are the #s I see but have no idea if they are acceptable :/

i foresee a number of issues from inaccurate speedometer and odometer to wheel well and steering components clearance

assuming you’re mounting them on all four corners, I don’t think it’ll hurt the transfer case, but say you have an issue down the road, it may not be covered under warranty due to them being non-OEM size

FWIW, that’s a significant increase in size, but you’re listing two different sizes. which size are you considering?
275/50R19 or
275/55R19 (below calculations are based off the latter as that’s the title of your thread)

Considering winter tire / wheel set that is 275/50R19

if you’ll be trekking in snow, narrower tires provide more traction than wider tires, but 275 is the standard width for 20” anyway. when comparing, it would appear 275/50R19 shouldn’t pose clearance issues, but your speedometer/odometer will still be slightly inaccurate
