    I purchased a new set of Bridgestone Ecopia 422 plus about a few weeks ago. I have noticed that my mpg has slightly gone up and that the ride is soft but I get this loud road noise that is noticeable at highway speeds. Does anyone have these tires and have they ever noticed this?

    I have had them for about 12k miles, great tire IMO. Quiet, reasonably priced, and excellent MPG! I had another set of non eco tires before this for a short time, I couldn’t tell a difference even though these tires were suppose to be really quiet. I returned them to Costco and got the 422’s

    The ride is better than Kuhmos I had on. I also saw an increase in my mpg but the noise is still there. I probably have to break them in. I will post an update after 10k.

    There’s an American and Mexican version of this tire. And a rarer Japanese version. The latter was OEM tire on some Prius. All three have tread variations, and other stat variations.
