In owners' own words
Verbatim excerpts from complaints filed with NHTSA about Michelin Harmony. Reports are published by NHTSA as filed and are lightly cleaned here only to remove intake codes.
I WAS GETTING AN OIL CHANGE AND THE ATTENDANT DOING THE CHANGE POINTED OUT A PROBLEM WITH ALL FOUR OF MY TIRES. THE SIDEWALLS HAD MULTIPLE CRACKS IN THEM. SOME ARE AN INCH LONG AND LOOK DEEP. THE MANAGER OF THE FACILITY SAID THEY WERE CAUSED BY THE SUN. I CONTACTED MICHELIN AND THEY SEEMED TO AGREE. I DON'T BELIEVE IT. ALL FOUR TIRES HAD THE SAME PROBLEM. I DON'T HAVE MY RECEIPT ANY LONGER. THE TIRES WERE PURCHASED IN FALL OF 2008. I THINK THE CRACKS ARE DANGEROUS AND COULD RESULT IN A BLOWOUT. I READ ABOUT 5 BLOWOUTS THAT OCCURRED WITH THESE SAME STYLE TIRES WHERE THE DRIVER DID NOT KNOW WHAT CAUSED THE BLOWOUT. MAYBE THE TIRES HAD CRACKS. MICHELIN DOES NOT MAKE HARMONY TIRES ANYMORE. AT LEAST, I COULDN'T FIND ANY FOR SALE. TREAD DEPTH IS ABOUT 7/32". I HAVE PHOTOS THAT SHOW THE CRACKS WELL. I YOU WANT TO SEE THEM, LET ME KNOW.
ON THE 28TH OF MAY I WAS TRAVELING 60 MPH (THE SPEED LIMIT) AND MY BACK PASSENGER TIRE BLEW OUT AND I LOST CONTROL OF MY CAR. I STOPPED WHEN THE BACK PASSENGER CORNER RAMMED INTO A CEMENT RAILING. THE BACK BUMPER, SIDE PANELING, WHEEL TIRE AND TRUNK HOOD WERE ALL DAMAGED AND NEEDED TO BE REPLACED. I DO NOT KNOW WHAT CAUSED THE TIRE TO BLOWOUT.
MULTIPLE CRACKING ON SIDEWALLS OF 4 MICHELIN HARMONY TIRES BEING USED 3000 MILES A YEAR. TIRES BOUGHT IN 2007 AND HAVE 99% OF TREAD STILL PRESENT ON TIRE. FEEL MICHELIN USED INSUFFICIENT UV/OZONE INHIBITOR CHEMICALS IN RUBBER COMPOUND MANUFACTURING THESE TIRES. TIRES MAY BE UNSAFE AND NOT DUE TO CAR OWNER'S FAULT. FEEL MICHELIN SHOULD REPLACE THESE AT THEIR EXPENSE, NOT MY MOTHER'S EXPENSE. TIRES SHOULD LAST MUCH LONGER THAN 7-8 YEARS AT 3000 MILES A YEAR WHEN 80,000 IS ADVERTISED FOR THESE TIRES.
THE CONTACT OWNS A 2002 BUICK LESABRE EQUIPPED WITH MICHELIN HARMONY TIRES, TIRE SIZE P225/60R/16. THE CONTACT STATED THE SIDEWALLS ON THE DRIVERS REAR AND FRONT PASSENGER SIDE WERE BREAKING AWAY FROM THE TIRE. DURING A STATE INSPECTION, THE INSPECTOR CONFIRMED THAT THE TIRES WERE SEPARATING. THE DEALER AND MANUFACTURER DENIED ANY ASSISTANCE WITH REPAIRS TO THE FAILURE. THE VEHICLE WAS REPAIRED. THE FAILURE MILEAGE WAS UNAVAILABLE AND THE CURRENT MILEAGE WAS 108,331. UPDATED 09/07/11 *BF THE CONSUMER STATED THE TREAD ON THE TIRE IS 7/32", BUT WHEN IT WAS FIRST PURCHASED, THE TREAD WAS 9/32". UPDATED 09/09/11

Michelin harmony: what the numbers tell you
Manufacturer treadwear data for the Harmony is not publicly listed. This is common for OEM-only or track-day tires that don't carry a US treadwear warranty. No mileage warranty is published for this tire, which is typical for performance summer and track-day rubber where the manufacturer doesn't make wear-life claims.
Cabin noise data for this tire is not published by the manufacturer. As a general tire built for the passenger segment, the Harmony is positioned against direct rivals within the same category. Comparing it to a tire in a different category (e.g. summer vs all-season) makes the spec sheet misleading because the design targets are not the same.
The Michelin Harmony has been part of Michelin's catalog since its introduction, and remains a current-production model.
