7,500 = 12,000 miles is about all you get on the rears on our cars. The negative camber settings really wear out the insides of the tires, but it also gives your car better and safer handling around corners so it's a tradeoff most find worth the cost.

When you put new tires on the rear, have a four wheel alignment done. It may be that one of the rears is not in alignment and that has caused one to wear more than the other. Two other causes are taking left or right turns much harder or faster, or one tire being pumped up with more air than the other.

Welcome to the expensive world of Porsche ownership. I budget $650 a year for rubber and replace all four about once every 2 years with light driving.
