I have Yokohama 16 ply tires on my Phaeton and I run 100psi in all six. Weight is a factor as others have mentioned. When I replaced my old ones the truck tire shop told me to run at 100psi. Nice ride and I am very pleased.
Good luck;)
So, what you're actually saying is that you have no idea as to whether you're running on tires that are under inflated or over inflated and please correct me if I'm wrong here? I mean this truck shop could have got the coach weighed, I guess.
Now, if I was to go with a number and rather pull one out of a hat, I would look at the rig's GVWR for each axle and use the tire inflation chart to coincide with that number, then add a little cushion, as previously said. Having said that, you could be under or over the gross weight and I for one, like having some idea as to which. Also knowing the total GVWR helps when determining the allowable toad weight by subtracting that number from the GCWR. I guess I just like knowing things, is all and am a curious sort of person, anyway.
