Question Hercules H-901 installed, what PSI should they be at?

I just picked up my rig from getting Hercules H-901 installed, the tire guy said to run them at 85lb. I asked him to go to 100lb has they are rated for max 110. I called a few tire dealers and they all said 110 is max best to run at 100 to cover the weight limit of the trailer. My TPMS only goes to 100lb so I think I should be okay. Thoughts on this information?

If you can’t run them at 110 100 pounds will work. The more pressure you run the more weight they will carry and the cooler they will run.

these tires are 125L rated so from what this shows they are 3637lb at 75MPH max https://www.herculestire.com/support...-speed-guides/ My old tires had a max of 95 cold and I could see on the TPMS that is would reach 115psi when driving. So I think with my trailer being around 12,500LB that running at 100PSI should be a good fit.

I run my Hercules at 100 PSI. (3 years now, not a hint of problem).
