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...

+10 is a GY Marathon notation.
Personally I might inflate to max and run 65/70 but that is enough.
Go easy in the 90+ heat either way.
