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 +10lbs, or 45-50psi, why can't I travel 65-75mph?

If this a per mfgr thing, then it is no wonder we get tired(pun) of digging around in the fine print where the real ST specs are hidden!

HTH;
John
