FOr what is it worth, my SE (2007, all factory, 70,700 miles) eats a pair or rear tires in 14,000 to 20,000 miles.
The fronts last a bit longer, but I usually change all four anyway just to get it out of the way.
Our cars take curves REALLY well, but this is due to the setup in the four wheel independent suspension, it is hard on tires.
But that is the trade-off to obtain the capabilities of a sports car.
My Ford Ranger has just over 60,000 miles on a set of tires that I have not EVER rotated, and they are wearing very little and evenly - but the truck does not understand curves.
