Kas, thanks for the explanation... that takes care of that question.
There are a number of us seeing the same wear pattern. I'm know I'm
running too much negative camber front and rear on my TR4A because I've
never changed it since I got it as a SCCA car. However, others with
less camber apparently are getting the same wear. Maybe the question
now is, who is using Hoosier Vintage TDs that gets a different wear
pattern and how are those cars set up? Thanks, Don

Might as well give an opinion. Probably okay to move the rear tires
to
the front (never to the opposite side) but when the fronts are worn they
are
DEAD. Don't move them anywhere but the dumpster. NEVER turn the tires
inside
out. If you've never had weird handling before you will certainly have
it
now if you do. The tread takes on a "feather". This is the blocks of
rubber moving under load by rolling away from the pavement. The inside
of
the tread block wears when the tire is compressed and this leaves a
definite sharp edge you feel with your fingers as you stroke across the
tire. If you turn that tire inside out you have the high sharp edges
exposed to the brunt of the cornering and they will not take the weight,
thus you will feel just like on hard packed snow.
