I'd still be looking at tire pressures, I'd say 32psi is too low for a non run-flat winter tire on the front of a 335i xDrive. RC will be quite different, IMO, (front to rear) on the softer rubber.

I'd be experimenting up to around 36psi on the front, if I had the issue on a car. See if things change.

I was running 35 - 36psi on the front of my E91 RWD 330d 17" non run-flat performance winter tires, and they were still on the softer edge.

BTW, what is the load and speed rating on the tires? That could be a clue to what is going on.

On the trouble shooting front you have changed tires, that is where the issue will be, pretty much for certain, rather than issues with the car itself, or systems.
