    Aha! When I took a closer look at the wheel nuts, I found that they are stamped with torque range (450-500), so that takes the guess work out of it.

    The wheels should be installed with 500ft/lbs. After 100 miles, retorque to 500ft/lbs.
    It takes nothing to do. There are some companies that require you to either get it done at a tire shop, or do it yourself.

    I have no issues doing it. I have my drives rotated every 6 months. You'd be surprised how many lugs are loose when doing the retorque.

    Cheers,
     
    BoxCarKidd and camionneur Thank this.

    Take extra care that mating surfaces are clean and you will never have one loose.

    I was reading on one of those sites linked that if they repaint a wheel, depending on the thickness of the paint layer it can cause issues too, so checking torque on a nice white clean wheel may be just as important.

    Enough that you're glad you did the retorque after 100 miles

    ####, I've never seen a torque wrench in a tire shop or my shop. Did have one set of duals try to jump an overpass once about 2 days after having a shop put new tires on.

    I also can't believe I can't say a word closely resembling darn that sounds the same as a structure designed to hold water

    That is true. Any time we do under carriage on equipment or change cutting edges on blades, we have to take a grinder and wire wheel to the mounting surfaces. A little paint and rust will cause bolts to loosen up.
