Okay. The X One was a top-line long-wearing tire that Michelin had in the very early 2000s. It's still the name of a current large truck tire, but they had a passenger car tire called the X One. If I'm not mistaken, it had a 90k mile tread life warranty -- unheard of at that time.
In 2004 or 2005 or so, Michelin replaced the X One with the HydroEdge, their new long-wearing tire designed to appeal to buyers looking for a premium tire. The HydroEdge was supposed to excel in wet weather. I think most just found them loud and hard. At the same time, Michelin introduced the Harmony line, which was their "mid line" tire. The Harmony was sold at independent Michelin dealers, Tire Rack, etc. The X Radial was sold at warehouse clubs. The Agility was sold at Sears. And the Destiny was sold at Discount Tire. I don't know if this line replaced anything...possibly something like the MX4.
I believe the Premier line replaces the HydroEdge and the Defender line replaces the Harmony/X Radial/Agility/Destiny.
