    all.

    My Avid Ascends (Not LX or GT) from 2019 are wearing on the inside and outside edges. I rotate them every 10K miles and keep them inflated, usually to 35 PSI.

    The wear pattern seems to indicate underinflation rather than a camber problem.

    They have an 85K mile warranty, I'm looking to have to replace them at 55K. Not unheard of, as mileage warranties are more of a relative comparison than an indicator of how much life you'll get out of them.

    What tire pressure do you run your tires at?

    42/40, but it's not necessary. the good thing is, i don't have to check them often, and the higher pressure seems to seal better.

    Try 42 front and 40 rear. I've been running Avid Ascends for at least 7 years on the various Gen 2, 3, & 4 Prii I've owned. I get very even wear.

    I wouldn't be surprised if the wheel (mis)alignment angles causes wear on either edges.
    Being within the green (zone) isn't good enough I suppose.

    You might have something loose in the front suspension like a control arm bushing or a ball joint.

    I ended up replacing my Ascends at 55K with OK tread in the center but worn on the inner and outer sides. I had a tread separation on the highway 5 years ago when a tire had worn, don't want that experience again.

    I'm back to Defenders, loved them when I had them before.

    I like the Defenders too. At 58,000 now. I will be happy to get 65-70K.
