I don't _know_, but it seems quite likely.  I do know that TR6 steel rims fit
quite nicely.  Of course, the _tires_ may still interfere.

I wouldn't go more than 1/4" on spacers ... for one thing, where will you find
longer studs ?  The TR6 wheels already have some offset, adding much more is apt
to shorten the life of the wheel bearings as well as increase steering effort.

Again, not on wire rims, but they work fine on TR6 steel rims.  My "late" TR3A
is still wearing 205/55-15 tires, but even after some massaging of the sheet
metal, they still rub the fenders at times.

I'm sorry, I don't believe there is such a thing as a "safe" wire wheel;
especially if you plan to drive the car hard.  My advice would be to pick up a
nice set of alloy wheels instead.

One of my brand-new Dayton wire wheels (with the oversize SS spokes instead of
weaker stock chromed spokes) turned up with broken spokes within 6 months of
installation on my Stag.  And after only about 2 years of daily driving, there
is significant wear showing on the splines.

And with the exception of the auto-X at last year's VTR convention, I don't
drive the Stag nearly as hard as I drove the TR3A.
