    That's where I keep my Yokohamas anyway. 42 front, 40 rear. Very comfortable and perfectly even wear.

    But whether you like the doorpost pressure or something higher, if it's flat spots, they'll go away in a while anyway. :)

    It's been a couple of weeks now since I adjusted tire pressure. They weren't as low as the door sticker but I did add a couple of psi all around. Also got them more consistently set than they were.
    So far I think it might be helping. Can't be sure just yet.

    Replaced Toyo with 2 Bridgestone Ecopia EP422 Plus on rear, both wife and I noticed the noise.

    Sorry, you mean you noticed the noise before changing the tires? Did the new tires fix the noise?

    We noticed the noise AFTER changing the tires.

    I moved 2 Ecopia EP422 Plus to front, Toyo to rear, feel better, hear less noise. Probably front has better noise isolation.
