Great thread. We have an 04 Hyundai XG350L...it came with Michelin somethings, and had a bad pull to the right for the first 18or 20k miles, when we finally took it to the dealer and said fix it or else. They put on a pair of Mich Harmony on the front, charged us about $30/each and told us to not rotate until the others were ready for replacement and then put on new tires and rotate. We bought Goodyears at Sams club, right pull came back right away plus a "nibble" in the steering wheel. Took it to the dealer, he said it is the tires again. Called Sams, they'll take the Goodyears back, so put on the Harmony tires, but at full price. They said that the tires on it cost much more than the Harmony, and I thought at $108 it's plenty. But treadwear...these original tires only lasted 33k, on the back for most of their life.
BTW, Hyundai's 1000000000000k bumper to bumper warranty does not cover tires, even if they are well below rated mileage.
We do like the Harmony, good to know that they are labeled with different names at different places. Thanks
