Question for you gurus running the Hossiers aforementioned.  My car is
FWD with roughly a 30/70 R/F weight distribution.  I run my fronts at
around 50 psi, and the rollover looks just right to my untrained eye -
the shoe polish is rubbed off to the shoulder and no further.

The rears I run at about 45psi, and they don't roll a bit.  Lots of shoe
polish remains.  The tread is crowned somewhat.  My thinking was that,
by leaving the pressure up, and preventing the tread from rolling to the
shoulder edge, I was minimizing the contact patch, thus reducing
traction and helping to make the back end more loose.  This is how I ran
just the last weekend.  But, as I was packing up after my last run, it
occured to me that the rule says reducing tire pressure will allow for
less lateral traction.  But I was under the impression that, if the
rollover was allowed to increase to the point where they roll like the
fronts do, that would give me more traction on the rear axle.  I haven't
had a chance to test the theory either way, but would like to have some
inputs from anyone who knows what I can expect.  Would reducing the rear
pressure reduce the lateral traction, and vice versa?  Or am I doing the
correct thing by leaving the pressures way up?

TIA to all.

PS:  How many people did I confuse with that narrative?
