Any chance this would affect the DSC in MSM mode ?

Nope, works fine. The most important rule is to keep rear tire height larger than the front.
The only time I’ve had weird DSC intervention was after a day of running 265/35 295/30/19 R7’s at the track and then driving home on my 265/285/35/19 4S’s. A few times going home the DSC would cut power around corners even when going slow. After driving for a day the car adapted and everything was fine.
This year I ran 265/35 305/30/19 71R’s and then switched to 255/285/35/19 4S the next day. No DSC interventions at all.
That 295/30 R7 is slightly shorter than the 265/35 R7, so that’s what made the car unhappy for a bit after switching. Was fine on track with DSC off, tho.
