It's all about vehicle weight, power and driving style. If you drive a 5500lb, 500hp vehicle hard in a city setting, 10-15k miles of tire life is not surprising or particularly poor. Long, gentle highway cruising will likely extend tire by 3x or more.
The factory alignment on the Cayenne is very mild - - almost no toe, and only moderate camber (~.5 degrees negative). With correct pressure, alignment and good bushings, tire wear is very even. Hard cornering (especially with braking/acceleration) will not surprisingly accelerate outside wear of the front tires, but overall wear is very even.
