How to you know when your tires have to be absolutely changed? My delaership changed only front at 10k, and said at 15k they would change the back. But at 12100k the back seem to be really rough all of a sudden. Does this mean time for a change, or is there a way to manually measure treadwear at home?

I believe the rule of thumb is to put a penny upside down in the tread and if you can see the top of abe's head then its time for tires. I believe 3/32 is the recommended minimum you should run around on safely, especially if your in an area with rain or the roads get slick alot.

Here in NM I can run mine a little longer just because its drier and we have few days of actual moisture where the roads actually get hazardous for me.

Had my 10k service today and the report says 6/32 on all tires. Is this good considering the mileage? How long are these tires supposed to last (I have the Bridgestones).

15k miles is about average for any summer only performance tire, dependent on driving style. I have currently around 22k miles on my 09 IS F and i'm at about 6/32" fronts and 4/32" rear for my factory Michelin Pilot Sport PS2.

As stated, you should be able to get around 15-20K on them, some longer, some shorter. Its completely dependent on your driving style, roads of travel and how much abuse they take.

I'm currently at 25,500 at the moment..So far so good despite fast driving..
I guess it depends how are your braking since it tends to wear out the tires..
