What pressure do you actually need in a G-rated tire? I'm asking because I put one Sailun G-rated tire on my Hitchhiker-II after a blowout in May. I'm running 80 psi in the Sailun, same as the other tires: two F-rated, and one E-rated which hasn't blown out (yet).

You need to run max pressure to get max capacity. For example, here is Goodyear's inflation table for their RV tires. Scroll down to the second chart and you'll see the 614 specs.

Inflation table for GY G

Weight/inflation
3170----85
3300----90
3415----95
3550----100
3675----105
3750----110

Changing from E to G tires most will need to use the top number and inflation. NOT MAX PSI!!!!!!

What in the world are you talking about with all your exclamation points? I said to get the max capacity you need the max psi. In other words, different pressures get you different capacities. I never said that everyone needed that. Calm yourself and take a deep breath. It's going to be ok.

No one seems to understand the charts are there for a reason (some do). If you are running stock tires stick with what your RV mfg states and that number will most likely be MAX psi for the tire.

I am trying to make it clear that when going from let's say an E to a G tire one should use the inflation charts and not blindly airing to 110psi as shown on the side of the trie.

GY Tech will tell you to go by what the RV mfg says! But they WILL tell you to use the inflation/weight charts when upsizing the tires as in E to G.
