This just keeps getting curiouser and curiouser...
In my Bentley Spitfire shop manual it shows a photo of the hub adapter and
the nuts that are on it aren't beveled on both sides. The outside face is
flat. There is also the warning that lug nuts used for pressed steel wheels
are not acceptable for use with hub adapters.
Narrower lugs would sure make a lot of sense, since the clearance between
11/16" nuts and the hub shaft is less than the thickness of a socket head.
I've already tried tightening down my wheels with an open wrench. I sure as
heck don't want to attempt THAT again! The book recommends 45 foot/lbs of
torque on the lug nuts. Once I get the correct set, I'm going to make
certain that they'll all flush and very snug. A local Brit mechanic says he
goes to 50 foot/lbs.
Cheers,
Jeff in San Diego
