Yeah, Hydroedges for this car is overkill. I had a set on the Prius for a couple weeks, and returned them under Michelin's 30 day no-questions-asked wty (replacing them with MXV4-Pluses; a much better fit for my car). They felt solid enough, and handled well, but especially at low/mid speeds, the tread noise was awful. Also, I took a substantial mpg hit. This may be an unfair criticism, as I did not give them time to break in.
