The flat tyre monitor counts the revolutions of the wheels using the ABS sensors - if you're going straight and the rate at which one wheel is spinning changes then the monitor assumes there's been a change in pressure on that wheel (tyre) and flags it up.

Now, if you hit a pothole and it nudged your tracking out then one or more wheels might start scrubbing, which would change their relative wheel speed.

Definitely worth getting the wheels checked anyway but hopefully it's just tracking and this can be adjusted back to normal.
It seems logical to assume it is tracking as the car is pulling left. The high speed vibration is what worries me more. Could the tracking cause this too?
