well i got 5k out of the stock 18's dono about the 19's

 

14k so far with probably 6k more to go. Mostly freeway miles though.

 

13.5k so far. Perhaps, I can squeeze another 4-5k out of these tires.

 

I'm going through them like butter.

 

how can you tell when they finally need to be replaced...im at 16k miles but they were most if not all highway miles..road noise is terrible at 25-0 mph...

 

I'm on 19,xxx miles right now. Front's look good. Rear might need to be changed out in a few thousand miles but i'll probably change out all of them. I do A LOT of highway driving though and I don't do burnouts. I do drive the car "fast" around turns and what not.
