Granted, my M50 is on order, but I've been on the this and the i4 talk forum for a little while now.

From what I understand (and from my own experience with hankook tires on other cars), out of all the OEM tire options on the M50, they wear out the fastest, by far. The sport hankooks I've had on other cars are great, but they have worn fast for me... however the quick wear borders on ridiculous for the M50.

There is likely more tire wear in the rear because even though the car has power to all wheels, the delivery is very rear biased. A lot of the time the car is full RWD unless the front is needed for launching, cornering, etc.

Maybe try swapping out the tires completely for a full set of another brand of OEM BMW star tires. The pirellis and michelins will likely wear much better.
