Ooops again

That looks better, did you tighten them up with a Torque Wrench?
BMW TIS says 120Nm +/- 10Nm (88.5 +/- 7.4 ft-lb) for an M12 thread.
Also put some copper slip grease around the centre spigot that the wheel centre locates on to prevent the wheel corroding onto it, the purists don't reccomend putting anything on the bolt threads as it has an effect on the tigtening torque.
Bolts failing are probably due to tyre fitters using impact guns to do them up that are not set to the specific torque setting, I have noticed that the tye fitters I use alsways use a impact gun to take them out, when refitting use the gun again followed by checking them using a torque wrench. Always worth going around them after a few days with the torque wrench just to check them.

The first thing I always do is remove the locking wheel bolts and throw them away, far more trouble than benefit.

Yes torque wrench to 120. Have copper grease but read so many conflicting things and there was some on there anyway so left as is.
