I feel I drive pretty spirited (I live around ALOT of windy back roads, so locking up the brakes into corners, and such is not uncommon, and I attend a couple autox's a year) I also take quite a bit of long drives. Ill have the car one year soon, and I will have 20k miles. My tires are basically done, they could be better, but I unfortunately neglected to rotate my tires earlier. So all these people getting way less, well they are either doing burnout galore, or did the same as me and did not rotate. If rotated every oil change I feel you could get 25k out of them, maybe more depending on your driving style.
