The tires (Kumho Powerstars) have about 15,000 miles on them. Last rotation was in June.

The front left tire tread is worn about half-way, but the wear is even.

The front right tread is worn nearly down to the wear indicators, but the wear is perfectly even across the tire. (No outer edge wear suggesting a bad UCA or anything like that.) Is there a suspension component problem that could explain this? Or am I just getting what I paid for with the cheap Chinese tires?

I'm planning to put a new set of Michelins on the car soon but don't want to end up back in the same place if I need to address a suspension problem.

By the way, the rear tires look just fine with even wear.
