The front tires on my 2010 328i, just 12k on it, are feathering. The rear tires are down to the indicators. These are run flat. The service tech asked if two people drive the vehicle. Is feathering really dependent on the number of drivers? or is it more about what's going on at the front end? Insane. Thanks for the feedback. PS. The dealer tech is calling BMW to get assistance replacing the tires... Let's see what happens.
