You should be just fine. Not sure what you mean by slip sensor, unless you mean VDC. If that's what you are referring to your fine. I would have advised 245/40 19 but if you already have them you are set. 275's on 9.5 isok. I think 9.5 to 10.5 is the suggested range.

 

275/35/19 S.Drive tire on 19x9.5 30 offset if your camber set -2.5 still have like 5mm stick out.
