At what psi can I travel 65-75mph?
This Maxxis pdf has the same table. Using the table(s) above, my ST175/80R13 with 1060lbs load could run at a minimum 35psi with ~4% reserve capacity. Is there a +10lbs rule? I run with +1...

Just to muddy the waters some more:
Has anyone actrually looked at the tire to see what it says? I'll bet it says " Max Load XXXX at YY pressure". That does NOT indicate a maximum inflation pressure.
My current tire is Milestar; original equipment.
I reads "Maximum load 1360lbs at 50 psi cold".
We move one step closer to my 60psi interpretation of the 'industry standard' for traveling between 66 and 75mph. :)
