for what it's worth, chrysler products used LH and RH bolts to hold the
wheels on for many years (certainly from mid thirties through sometime in
the 50s) - note: "bolts" not "studs". it really confuses some tire stores
when they can't understand why the impact wrench doesn't do anything to the
"nuts"

By the way, those wheel nuts have left- and right- handed threads
depending on what side of the carriage they are for, so that they
won't unscrew themselves during forward driving. This in addition to
locking pins and, in some cases, opposite-threaded, smaller diameter
castellated locking nuts. Apparently, wheels coming off at speed was a
Serious Incident, and some rather ingenious engineering was employed
even on cheap, otherwise low-quality wagons. I've never seen such
opposite-threaded nuts on modern carriage axles.
