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...

The sticking point for me is trying to understand that
" PSI is obtained from the inflation/load chart for the tire and using that pressure plus 10 PSI"
is equal to
"cold inflation pressure by 10 psi (69 kPa) above
the recommended pressure for the rated maximum load".
Goodyear says the latter.
