I'm not sure why only one of your tires was going bald, but I do have a say about the mileage.
I acquired my 97 1.9 from a friend (JRL) this year with a set of "somewhat used" 235/40/17 Dunlops on it. During the homecoming trip I had a tire blow out on the rear - and it was well worn, but mostly on the inside. After checking the other rear tire, I discovered that the tread was wearing out faster on the insides of the back tires. The tread on the visible (outer) area of the tire looked fine BTW - I did look at it before leaving :)
Fortunately for me, Larry (BMW Tech) was along on the trip. What Larry told me was also backed up by the techs at the factory. What I was told was that the negative camber (non adjustable in the rear without a kit) was what caused my tires to wear faster from the inside outward. The fronts have pretty even wear on them.
As for the change at 22K miles - when I talked with the dealer who was installing my new Michelin Pilots he said that was about normal. The tires were expected to last somewhere between 15-22K miles. I asked him about the warranty - his response was "Warranty? There's no warranty on these tires - they're racing tires and aren't expected to last very long". So, if low profile high performance tires are what you like, be prepared to plunk down some cash every 20K or so.
