Previous thread covering your inquiry in +5 sidewall sizing but also in regards to all-seasons.
But TLDR; is no issue since overall front and rear tire sizes are within 1%. And if you're fine with ONLY summer performance tire options.
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.
