The Michelin chart says the maximum tire load single psi should be 130 and for dual 120. Suggestions on what to run them at then?
I'm certain there's going to be more than a few opinions on the subject but based upon what I'm reading the guy who I bought the RV from was obviously full of it.. He ran them at 95 PSI!! I took them to 105 but sounds like that might not be right. Look forward to the input even if I need to be taken out behind the shed. Only way to learn sometimes.
Thx.

I agree with the input on getting a four corner weight. But the previous owner may not have been full of it
! We just replaced our last 6 out of 8 Michelin XZE*. These gave us good service, and actually Laszlo of TCI Tire Center, a pretty well known and respected tire man in the South West, said I could have gone another season on them. They were 6 years old, and no signs of any problems.
Your size is different then the 12R, so the Manufactures Tire Charts will show a different PSI recommendation then ours for the same weight. (Key is to recognize this is the 'minimum', and many run a 'contingency' 10% or so on top of that.
That being said. My XZE, per the chart, would run at 75 PSI on the rears and tags, and 90 on the Steers. (Not including my 10% and rounding mentioned above, that I personally do.)
Suggest you check the Fleetwood owners groups for others with our same year an model that have had four corner weights - that will at least give you a 'like coach' bearing to work off, until you can get your own four corner weight.
Take good care of those tires, as they are pricey, and they'll take good care of you

Best, and enjoy,
