Michelin vs AAA:

When approached about the AAA study last week, Michelin argued that the study matched—in broad strokes, at least—its own argument. "Michelin has begun a conversation about worn tire performance because we believe that consumers should have information about what they can expect from their tires throughout their legal life," the company said in a statement provided to The Drive. "AAA, like Michelin, is committed to safety, and we are pleased that AAA has added its voice to this topic. AAA's data supports Michelin's position that not all tires are created equal. The AAA research also supports our position that as tires wear, their wet stopping ability decreases."
"We also agree that tire degradation varies significantly among brands and even within brands," the statement went on. "In fact, some worn tires perform better than some new tires. Wear bars are legally required for all passenger tires sold in the United States. Michelin strongly believes that all tires should be designed to perform to current wear bars, thus resolving safety, financial and environmental concerns."

Tom Carter, technical communications director for product marketing, said Michelin wants to give consumers more information when they are buying new tires.....
"Technology exists to design and manufacture tires to perform well in wet conditions, even when worn. You don't have to have magic sprinkle dust or a magic tread pattern. You need to have good tread pattern, and you need to maintain it. You need to have good contact patch shape, and you need to maintain it. And you need to have an adherent rubber compound that maintains this traction throughout its life."......
Carter said tire designers know what they need to do to make sure tires perform acceptably when they are significantly worn. Now it's time for them to do so, and for the industry to develop a wet traction test that will give consumers critical information they need to know when buying tires.
