@335iTitan : I do tend to take corners aggressively.
My fronts have smaller tread left than the rears. On a side note, I just discovered, that the RE050A I, staggered setup comes with different tire tread dimension. 11/32 on rears and 9/32 on fronts.
Its comforting to hear this isn't abnormal. Perhaps quite similar to tires on some of your E9x.
Thank you everyone for your responses. Much appreciated!
