2007 Mazda 3 excessive premature tire wear. At 30,000 miles I see that the front tires are worn to the point of steel band visible and sticking out. Inspection at 25,000 miles dealer said there was wear but not critical. The tread is separating and I am replacing tires immediately. I have learned that front suspension has excessive negative camber causing this.
