If the problem is the staggered 369M's, why would BMW deliver these?
Could it be the tyres? Have the factory default PZero's on the 369M's and have Nokian Hakkapelitta on the 305's.

Or is it just a coincidense?
To me, that appears to indicate a slight drivetrain 'bunching' issue on the staggered tyres.

Slight variations in tyre pressures and tread depth could be involved, and a staggered setup with a small RC difference, could just push the limits to make the drivetrain very sensitive.

Are others with the issues on staggered wheel setups?
