First couple trips I had them inflated to the 125psi they call for & it looked like a bomb went off inside the trailer. I have looked at the weight rating chart & have been slowly been reducing the air pressure in the tires. Last trip north from wintering in Fla I was down to 90psi & the tires still ran cool to the touch, & things were not as bad inside the rig. They are more of a truck tire & although they show no ware after about 15K miles I'm still considering replacing them with 16" Saliuns.

Your trailer is what 14,500 GVWR ??, Those 17.5 have got to be pretty rough. The Sailuns ,especially the 235/85/16 will cover whatever weight you are going to be, and then some.
My fifth wheel weighted at one point, not fully loaded 12,740 , and 2420 on the pin. Round figures 13,000, 2500, puts 10,500 on the axles or 2625 per tire.
Per Sailuns weight chart they sent me for the 235/85/16 45 psi for 2580 lbs , and 50 psi for 2760 lbs. . So say around 47 psi for the weight I have on my 235/85/16 Sailuns. Thats hard to believe around 50 psi on a 110 psi tire, but thats what the chart has . No I won't run that , but I may lower my pressure a bit, down to 90 cold . What I will do is weigh every wheel just to see what is on each one, I know pretty close the total weight ,but no idea each wheel .
