    Swapping wheels today on my roommate's 2017, and heard some fairly load sloshing sounds. Is this normal gas camel behavior?

    I've never noticed it before, which doesn't necessarily mean it's abnormal, but I'd still like to ask just in case something might be secretly going cattywampus in there. :D

    Are you sure it’s not coolant in the muffler?
    Could also possibly be air in the coolant

    I— oh... I'm not sure.
    (But also not sure if I'm missing a joke)

    Unfortunately, no. Check the coolant level to confirm

    Oh heck, okay. I'll take a look. I was about to take it out and test the new wheels/winter tires.

    Soaking of that, he's using the original lug nuts on the winter steelies. They turn down at least twelve turns, but stick out quite a bit because they're taller. Think that'll cause issues, or will it just simply look wonky? They tightened down okay and the wheels seem stable.
