BMW 320i Xdrive - bad vibrations !

[RPL43]

I bought a 2013 320i xdrive and have just fitted winter tyres to the standard BMW alloys. I noticed a vibration on the motorway at @ 60mph and above. I've had the wheels rebalanced three times since, and it hasn't solved it. I think this is coming through the body rather than the steering wheel, almost like the crank, axle or drive shaft is out of balance. It feels like driving an overloaded washing machine!
It is worse under acceleration in 5th and 6th gear from 60mph onwards.

Anyone else getting this issue?

Can you put the old wheels back on and see if it goes away (or did you just have the tyres swapped onto the original wheels)?

Sorry, just read your post again and you're using the same alloys!

Yes, I saw that posting, thanks. It seems there are other sites also reporting similar issues with the F30 model, not just in the UK either, but before I approach BMW I want to get my facts in order, fully expecting they will try and fob me off.

Thanks
