My 135i got 20k miles out of the rears and they were your typical BMW fare (Bridgestone RE050A run flats).
Information from Tire Rack recommends 4/32nds is replacement time.

I live in the Pacific Northwest and we get lots of rain and I will not let my tires get below 4/32nds.

Before watching this video I was one of the guys who used a penny to check tread depth.
