Mein Auto: 2010 135i M Sport

What a HUGE difference in ride quality and quietness. I got 25,000 miles out of the original run-flats, but would have swapped them out earlier if I had known what a big difference they would make.

Best of all, my local BMW dealer did the mounting/balancing swap for $120. Thanks to others on this forum who pointed me in this direction.

And you had no problem putting those tires on the existing wheels that previously had tires that were 10 mm thinner? I have always wondered if this was possible...this may help to dial out some of the perceived understeer that this car has. I am about to take delivery of a 2010 135i M sport and it likely needs new front tires soon. Thanks.
