While I appreciate your opinion, my opinion is more valid
My experience is with an e39 m5 running 275/35/18 and 100% power through the rear, weighing about 500 pounds more than my m3 but about the same as your S4, and I got 15k miles out of my rears in MY style of driving.
So, given the weight differential and the fact the M3 runs a slightly taller 275/40/18 rear tire, but accounting for the fact the M3 puts down significantly more torque, I'm expecting 18k miles to be a good run out of the rear tires and 15k to be the minimum.
P.s. All of this is premised upon the Michelin PSS on the M3 being the same as I've run on my e39 m5. Obviously the compound for the BMW-F80 specific M3 PSS might be softer and wear faster.
