[AT] Lug Nuts

[charlie hill]

Years ago I had a chevy pickup that was wearing a set of Crager's like that 
when I bought it.
I never could keep those things tight and turning in a circle rather than an 
ellipse.   I sold
the truck before I ever got around to fixing them or buying new wheels.

Those are a common style of rim actually. Unilugs. The idea is that they
fit multiple lug circles with one rim. Most use a shouldered lug nut
with a washer. There used to be kits out there with elliptical bushings
that you could install in the holes to make them center up better.
