The Michelin HydroEdge with Green X and Michelin Harmony are Passenger All-Season tires that provide year-round traction on dry and wet roads, even in light snow. With experience testing both tires while driving a sedan, I feel each tire is very good if used in the right driving environment.
The Michelin HydroEdge with Green X combines long tread wear and low rolling resistance with superb hydroplaning resistance. With a 90,000 mile tread life warranty, this tire offers excellent traction with a smooth and comfortable ride. During my testing of the tire, I noticed the tire lacks excellent traction during icy and snowy conditions.
The Michelin Harmony offers good hydroplaning resistance and an 80,000 mile tread life warranty. With an impressive balance of dry, wet and light snow traction, the Harmony provides a quiet, smooth and comfortable ride.

Even though both tires handle wet and dry road conditions very well, the Michelin Harmony handled the slushy and snow covered roads better than the HydroEdge with Green X.

Will 235/65/17 fit on the OE rim that now fits 225/65/17 0n 2009 dodge Journey?
Thanks
