Another note on coining. There was a TSB sent out by Chrysler in the late 80s and renewed as late as 1993 involving vibration from improperly centered wheels on models with coined wheels and shouldered lug nuts. The "fix" was to issue all D350 owners 2 conical lug nuts to use during tire changes. The sequence, IIRC, was to put the conical nuts opposite one another and tighten to 50 lb-ft. Put 6 shouldered lug nuts on, tightening to 50 lb-ft. Replace the two conical nuts with the shouldered nuts, and tighten to 50 lb-ft. Then properly tighten all of them, in sequence, to 300 lb-ft.
Because of this, I purchased 2 conical lug nuts from O'Reilly's and keep them in the glove box.
I have this TSB saved on my laptop, but I don’t understand it, because my old 16.5” wheels and my new 16” wheels both fit nice and tight on the studs. There is no slop whatsoever, so the coins can’t help but to seat on each other.
