[Fot] Hoosier R6 tire pressures

[Norlin Engineering]

Just reread this post, and I think I see the difference.  I'm running 2 1/2
degrees camber up front and 4 1/2 in the back.  Maybe the solid axle cars do
need to run the higher pressures.

"to cure for 24 hours. I understand there is some molecular
realigning going on during the cure period.

FWIW -
After talking with the Hoosier tech guys, this is what I gleaned: Heat cycle
a minimum of 24 hours before race temps. 5+ days after
heat cycle is preferred and anything under 24 hours doesn't do
anything. 15-20% increase in tire life with proper curing procedure.
Your results may vary but my results look to be at the high end ++.
According to them, a 2000 lb car will reach maximum grip near max
pressure of 41psi/cold. The trade-off will be less predictability and
a abrupt break-away... Fine by me.
That said, I run 38 front/36 rear cold on a 1977 lb, solid axle TR4
with -1/2deg camber up front.
