Summary: These tires are on my 2007 Prius. I expected them to work well in just a couple inches of snow. The first minor snowfall rolled around and I found out that it was like ice skating. These tires replaced my old snows but for me are extremely inadequate. The gas mileage on the also dropped 5 to 7 mpg.
Summary: I had no problem with the tyres as they were rolling, the main problem I had was that they were very fragile, I bought 6 tyres and lost 5 of them within less than 11000 KMs: 1 was torn in a small collision, the sidewall broke 1 had a baloon due to a pothole in the sidewall and eventually broke 2...
Summary: Michelin Harmony is not a good tire. They do not perform well in the rain. I have an Avalon and I was looking for a smooth Avalon ride, these tires are noisy, they are not good tires. These tires have caused me not to purchase any more Michelin tires. I do not like them.
Summary: Démarrage sec sur route séché le pneus patine d'office , sortie de rond points catastrophique , aquaplaning rapide sur trombe d'eau , impossibilité de rouler vite , bref après 18000km je les ai remplacer par des yokohama depuis ma voiture très bien .
