[TR] Panasports, Redlines and Lug Nuts?

[Ashford Little]

I was putting air in the spare tonight in preparation to leave for the  
TRials tomorrow morning and I got to wondering & worrying.  Suppose  
you had a massive blowout of a tire on one of your Panasports or other  
new allow wheels and had to put an old steel wheel in it's place for a  
while.  Would the lug nuts for the Panasports secure the steel wheel  
securely to the hub?

I'm not planning on having a blowout and 215/60/16 tires aren't hard  
to find, but I wonder...

Thoughts?
