You indicate your tires are 12 ply tires, so the 110 PSI should not enter the picture.

What brand, size tires did you buy? Given that information, every manufacturer has a specifications chart for their ST tire lines which gives the maximum pressure/load information.

You can find the Carlisle Radial Trail HD information at this link: https://www.carlislebrandtires.com/o...adial-trail-hd


Carlisle's 12 ply tire only comes in one size and is the last entry at the bottom of the chart. If you have a competitor's tires, they "should" follow very closely with the pressure/load ratings, but may differ, so check your specific brand to confirm.

Find it interesting that the table lists the max load at 10 m.p.h. and the max speed ratingings at up to 81 m.p.h. depending on tire. I would love to see a graph with load rating vs speed rating to see where the load rating is at highway speeds.
