I have a 328is and recently upgraded my wheels and tires. I had 16 inch rims and 225 tires but upgraded to 17 inch wheels with 225's in the front and 245's in the rear as recommended. Trying to save some money, I purchased brand new Falkens ZIEX ZE912 tires. After I got these tires mounted and balanced, I am experiencing humming sound from the rear...precisely at about 40/45 I get a low hum and at 70/75 miles I get a high hum but when I get to 80 miles the humming goes away...Does anyone have any idea what going on?? Someone said it might be my bearings but my mechanic said my bearings are fine and he thinks it's the tires..

It's the tires. Since you have a larger contact patch on the road in the rear it is likely you will hear more road noise. I don't personally have any experience with Falken tires but if the ones you purchased are more performance oriented they will tend to be slightly louder than what you're used to. Chances are you'll get used to it and you won't even hear it anymore.

Humming from the rear ay??

Try more fibre in your diet....

Are the tyres wearing normally?? are they making the noise from when the tyres were put on or are they slowly getting worse???

Thats interesting. I am fitting 18" SSW wheels soon , 8" in front and 9" at the rear. I am fitting Falken S076 Phantom tyres, 225/40 in front and 245/40 at the rear. I will let you know if I have the same problems.

I have now been using the new rims and tires for about a week and I find the ride super smooth and the handling much better too.
