My GS was delivered with Mitch's ZXZs 245/70R 19.5s. They were H rated with 120 psi max rating. I'm thinking that a G rated tire isn't enough tire for your GS. I run 95 psi with a tire monitor system and in moderate temps pressures increase to around 110 psi and 95 to 105 degrees F. I now have a full set of Toyos H rated same temps and pressures in moderate ambient temps. Summer driving will increase temps and pressures. With the assumed weights and the GS being pretty heavy out of box my opinion is that the Gs may not cut it.
Get the rig weighed and chart it to see what the tire pressures should be. You need full fuel, water and propane and all the equipment that you would normally travel with. That means clothes ,food and condiments. Don't forget the dog. Hit the scales. Keep in mind the published axel weight ratio. Ideally individual corner weights would be the way to go then you could inflate per the weights at each corner. Its pretty difficult to find a place that can do that unless a Dot inspector wants to practice.
Anyhow summer driving heat will be the test.
Just my opinion.
