As others have stated there will be changes to your calc speed:
Going +5 in front increases overall diameter by 96mm to 114mm = +14%
When speedometer reads 60 km/h actual speed will be 62.2 km/h
Revs per mile is 4% less, from 682 down to 658.
All what ever size changes you make, you want to ensure there is 1% or less differentiation between front and rear cause well xDrive.

You're not going to have any +5 options for 22" all seasons.
There are no 275/40R22 + 315/35R22 all seasons listed on TireRack and you'd need to either stick with OEM 275/35R22 + 315/30R22 or go 285/40R22 + 325/35R22.
275/40R22 + 315/35R22 = No A/S

Sticking to your +5, 285/40R22 + 325/35R22 = 1 A/S
