Tire Tread/belt problems of the 2005 Toyota Matrix

Today, the roads are slightly slippery, but while everyone around us stopped at a traffic light without problem, my wife and I were unable to stop, careening through a red light. Thankfully, there were no oncoming cars. The problem is, we discovered, our tires. Our Toyota Matrix xr 2wd 2005, and our oem continental tires, has 29,078 miles. Yet our measurements indicate that all four oem tires have a tread of 2/16" (outer) and 3/16" (inner). This is premature wear. Our dealerships service center has said that they have found this to be a problem, yet they offer us no help or solution.

Continental tires were all cupped at 15,000 miles dealer replaced all tires with different brand new tires cupped again at 20,000+ miles dealer claims nothing is wrong with car.

The contact owns a 2005 Toyota corolla Matrix. The vehicle has continental tires, size p205/55/r16. The contact stated that the tires look as if they have been cut down the middle. The manufacturer will not warranty the tires or provide a replacement set. The tire failure mileage and vehicle current and failure mileages were all 24,000.
