 Damn, I just dropped a battery on my foot. ouch. Damn.

Like I said, the Hoosiers are bias ply. If you run camber set up for Radials
it will be way too much. Bias plys have stiff sidewalls. When I run Radials
I run 3 degrees, with bias ply it should be about 1 degree though Peyote
seems to feel better with two. when you go down the straight on bias ply
you'll be up on the inside edge if you run much more than that. My Hoosiers
have three race weekends and an hour of an enduro on them and they look
perfect except for a little wear on the inside edge from that extra degree
of camber. I also run about . They'll heat cycle out before they wear out. I
also run about 20 to 22 pounds cold pressure. Sometimes lower. Most folks
are probably at 22 to 24, but I found that to be too high for Peyote.

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.
