Last tire rotation I had done the tech said it was the firs time in over ten years he had ever seen all four tires within 1/64" of each other measured in 3 places each tire as far as tread wear is concerned.
They are holding up unbelievably well considering how I drive. It took a little getting used to when switching from 40 profile summer tires as the feel was not quite as sensitive for lack of a better term. But I can take the banked off ramp near my house at 65mph with the cruise control on just like the summer tires. The car just starts a very controlled even drift at the exact same point the 40 profile summer tires did. I love them. Will buy again.
