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...

In your quoted PSB, it is clearly stated, "Do not exceed the maximum pressure for the wheel".
If your "wheel" includes a 13" LR-C tire, it carries a maximum of 50psi. Now then, if your "wheel" includes a 15" LR-D tire it carries a maximum of 65psi.
Which do you have 13" or 15" LR-C or LR-D?

The O.P.'s opening post indicates his are ST175/80R13- I thnk LR-C is as high as those go.
That said:
The above post may clear up a point of confusion in my mind, that being the meaning/use of the word "wheel". I've been thinking of that word as interchangeable with "rim"....but if "wheel" is more correctly defined as a combination of both tire and rim, the lowest rated component would govern maximum capacity.
Is that correct?
