As an FYI, Michelin is replacing the HydroEdge and the Harmony with a new tire, the Defender. One of the benefits I have told...is that is has a stiffer sidewall and will work well for minivans, with their heavier weight.
I'm just coming home from dealership with a new set of 4. Between myself, and reading posts from everyone else, I figured we had tried everything that was already out there, so it was time to try something new. Coming home on the highway, they seem ok, and were quiet. I'll be taking a 2500 mile trip in about a month, (pulling a small trailer) so that will give me a better idea how they will perform. After the trip I'll come back and update this post with my thoughts.
Excerpts for a Michelin press release. (It says they will be available April 1st, so that's how new they are.)
“The Michelin Defender will replace two existing lines: the Michelin HydroEdge and the Michelin Harmony lines,” says Pete Selleck, Michelin’s new North American chairman and president.
Michelin says the Defender will stop 31 feet shorter than a leading competitor. It will also last 21,000 miles longer than the mileage of a leading competitor. The company also says a consumer who buys set of four Defenders will save $250 in fuel costs over the lifetime of the four tires.
Further adding to its safety features, the Defender tire maintains the same wet handling as the previous generation Michelin HydroEdge tire. It also has 15% increased snow traction over the HydroEdge.
The Defender tire has earned the Michelin Green X designation. Further mass reduction and a reduction in rolling resistance makes the Michelin Defender tire 17% better in rolling resistance than the previous generation Michelin product.
