Friends... Have been doing a lot of research on replacement tires for my 04. I now have 34K miles, and expect to get about 3 more months out of them. I have been trying to find rolling resistance data on the most promising tires, which is very hard to come by. Fortunately, Consumer Reports just released, in their November issue, a listing of all-season tires which includes the short list of possible replacements. One of the tires that has superior rolling resistance is the Michelin Harmony. Some here and elsewhere have reported that they have not taken a mileage hit with these, and some on TireRack have reported a mileage increase. I am seriously considering putting them on my Prius, but would appreciate any firsthand experience with them. Mileage, handing (especially in dry conditions), braking, etc. Thanks!
