110psi tire question...
Not to beat a dead horse but I am a little confused after reading many threads on the subject. I am running the Sailun S637 G rated tire with a max PSI of 110 which is what I have been running. I have...

Something else to think about is how stiff this Sailun tire is, and whether is the tread area is flexible enough to deform if full air pressure is used, but not full load is placed on it.
I've looked very closely at my Sailun tires when they are at full air pressure and the tread area is flat as a pancake, with no indication that there will be a problem with the center contacting the ground before the outer area. In fact at 110 psi in my Sailun S637 tires and a total weight of 12,500 lbs. on my triple axle toyhauler, that's 6 tires, the tires show absolutely no indication that they are doing anything other than tracking flat on the ground completely across the tread area.
Also, how many trailer haulers reset their air pressure when they're hauling an empty trailer? I would be willing to bet that no commercial trucks change their air pressure depending on how the trailer is loaded. Sailun S637 tires are labeled "For Trailer Use Only".
OTOH I run mine at 100 psi now because it takes forever to get them up to 110 psi from 100 psi. :) I have a TPMS and watch them pretty closely.
