Goodyear G614 air pressure
Not sure if this has been asked. Original set of tires had 80 pounds max pressure. The Good years has 110 max cold pressure. The tire shop put 90 pounds in them. My rims are rated for 110#. Since I ...

And gosh, I was so worried. Anything could have happened over these last five years of running reduced air pressure. But, unsurprisingly, it didn't.
Yeah.... lots of folks have used the old Carlisle's/Tow max and other ST poly tire maypops and had good luck with them. Most RV folks never wear a tire out and don't put many miles on a tire.
Here is another RVer that found a downside of going way over his actual load per tire needs....

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 replaceing 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.
