Cosmo -
I'm tempted to say you are completely correct and anybody with a set of
American Racing Mg Libres should get rid of them immediately and I will be
bravely take them - but you are dead wrong on a couple of points
- it is very easy to tell the difference between Mg and Al, once you are
familiar with both. A Mg wheel is incredibly light compared to an Al wheel of
the same size and bare Mg has a very different color and surface sheen
compared to Al. It is ridiculous to suggest that anybody who has seen both
can't tell the difference.
- while incredibly, dangerously, and explosively flammable once ignited, a
solid Mg object absolutely cannot be ignited by incidental contact with a
spark or open flame. Top drag racers used to use Mg manifolds - incredibly
dangerous once ignited, but not that easy to ignite. A Mg wheel is
extremely unlikely to ignite unless it is broken and the tire and car around it
are
consumed with flame first.
- you are correct that Mg wheels were likely last made in the 60s - they
are extremely rare and very valuable now - I would not trust them for
competition use, due to their age and possibility of cracks, but (properly
restored) they are uniquely attractive and are very much sought-after period
pieces.
Cheers,
Jack Mc

Hi List!
I was told, MANY years ago, that Mg wheels were band from racing, If
one was to
get a flat & the wheel caught a spark (wheel hitting the pavement
or another
hard object -guard rail/car) then it would be an instant fire.
When Mg ignites ,
the end result is powered because of the high intense heat
being given off.
Therefore; I thought all Mg wheels were band for being sold
(back in the 60'). I
really doubt that they are Mg, most likely AL, but you
may have a set of mg.
wheels. If that is true, then be glad that they never
received a spark or flame
to touch them.
GET RID of THEM! They are a
disaster waiting to haven.
