This seems to have generated massive confusion. I'll try and clarify:-
Standard Steel TR7 wheel uses 45deg taper seat nuts M12 x 1.5 (I think its
1.5)
Standard Alloy TR7 wheel uses a sleeve nut but Centres the wheel on the
centre
of the hub NOT the wheel nuts.
Compomotive and some others uses taper seat neat the same as the Steel ones.
Some after market wheels use sleeve nuts and some of those centre on the hub
others rely on the wheel nuts.

Subject: Re: TR7 BFH#36 - Lug Centric?
Can I get standard 1979-1980 lug nuts for TR7s from standard auto parts
stores (NAPA,
Schucks, Auto Zone, Pep Boys)? Do the wheels on Spiders take special lug
nuts? If so,
where do I get them?
