That is good to hear. I didn't have any handling issues with my 021s, but my front is burnt to the wear bars on both sides (middle is still pretty good) at 3600 miles while the rear is a little over half worn anywhere. I'll check the #s but I bet (know) mine came out of the bad batch.
I'll try calling them but doubtful that the're going to start replacing tires for everyone who calls in claiming "rapidly worn" front tires without an official recall in place. Ah well, doesn't really matter, I'm going Michelin next anyway.
