I'm not a car aficionado, nor even a car enthusiast. I bought these tires because a) there was a good promotion b) I don't really care about tires and c) I've driven on (and liked) Pirelli tires before, plus they have a pretty good reputation. These are the worst tires I have ever had on my car. The noise makes them truly unbearable. I had read other reviews commenting on the loud noise. I was dismissive, thinking these were probably just car fanatics who need their ride to be whisper quiet. But this is beyond ridiculous. I'm going to try to return them and hope the store will take them back.
Bought two tires for rear of my wife's 05 Prius and had them installed. I immediately noticed a severe over steer problem and thought maybe the shop had not inflated enough. Checked the inflation and it was on 34 psi. Increased the pressure to 40 psi; still the same over steer problem. Have had these tires on my car less than 5000 miles and now looking for more tires to replace these. I am an experienced driver but I am now afraid to drive this car during windy conditions due to the over steer. Purchase at your own peril..
