    Came here looking for reviews, because I'm about to pick them up at Costco.

    It's $70 off and $0.01 installation, so it's a savings of $130.

    I replaced my EP20s with EP422s on my 2010. With my 2010 with EP20s, I had a flat and it turned out the sidewall was only a 4th the thickness of the EP422s. I would say the thickness is on par with 2x of an inner tube. This equates to have greater rotating mass for the EP422s. After I changed to the EP422s, I had a 5mpg mileage drop. The EP422 which are almost worn out have never given the mpgs of the EP20s. EP422 are lasting longer (65k vs 90k).
    There may be an safety issue with the thinner side wall??? but then there is the mileage.

    I use the Ecopia 422+ on my 2010. I have 17" wheels. They ride better, and I get a couple more MPG, than the Nexen tires the last owner had on it.

    If you're shopping 17's it a moot point: the EP20 only come in 195/65R15
