That's what I was afraid of hearing . My '05 has the OEM 19s and so far I only have a lil over 6200miles on the tires. I haven't actually checked mine yet, but I'm hoping it still has plenty of thread left. We shall see.

So goin back to the question, I guess from the majority of ppl w/ 19s, I have between 5-7k miles left on my original Bridgestone's.

 

damn it i hate stock 19's infiniti can kiss my a s s.. they made me get the wheel and tire warrenty.. that bitc h told me if i curbed my wheel it will be covered and it ain't.. damn my back tires are bald... hahha

 

almost 25k- still have a little life left.. i'm guessing 2-3k more.

 

I replaced my rear Pilots at about 30k miles. Fronts still had some tread left when I replaced them at about 33-34k miles.
