Tire Load/Inflation Calculation
Exactly three years ago I bought new tires for my Jayco 23' (27'OAL). I had previously had the trailer professionally weighed at an Escapee's weigh station where they weigh the load on each tire. Unfo...

OK please tell me what YOU would do. I have about 4,500# on my GY "H" tires and the tires are not holding up with a rating of 4,805 @ 125psi. My next option is going to a "J" tire (not using Chinese made Sailun). What psi would you run as the "J" has a 6,005# capacity at 125psi.
You've said before you don't run max pressures in your Goodyear heavy trailer tires so its not a surprise your having tire issues from using low psi numbers from a minimum pressure/load chart.
What would I do with a 4500 lb load per tire?
First off I would never over tire a trailers above 15 percent capacity above the gawrs and I also would use the best tire on the market and its sure not a G/H/J Goodyear.

When it came time for me to replace our tires, I researched many different ways to go. I wound up purchasing 17.5" J rated medium duty truck tires and wheels. When all done and said, it was $5.00 per wheel and tire combo more than just replacing the 16" tires. This tire and wheel combo is good for 6005 pounds each. Using the inflation chart to get the pressure for the load, I inflated to 80 psi which was good for 4500 pounds per tire. With the first tow with these tires to Kansas City, I have made this trip to the speedway several times before, I was down almost 2 mpg both ways. The tires were 20*-25* hotter than the truck, which I have never experienced before. I inflated them to the side wall pressure, 125 psi for max load, before our trip to Florida. Now the tires run 5*-10* cooler than the truck and my fuel mileage is back where it used to be. I have always run max pressure up until I installed these tires, with what I have experienced, I will continue to run what the side wall indicates.***
He now should have a longer lasting tire. Hell even a Goodyear tire might make the grade.
