Most tire mfg's have inflation charts available like:
Michelin
and should be used if there is any question on load limits... I know I do :)
and as is the case with many tires (including st's) you CAN over inflate up to a safe limit to help with loading and or speed ratings...
(at least with mine you can :) YRMV)
Here's the load ratings through different levels of inflation for my LT275/65-20.
PSI Load Rating
80 3750
75 3540
70 3375
65 3195
60 3030
50 2680
45 2475
40 2280
35 2080
