Tire inflation
After weighing I find my front tires are inflated too much. The sticker on sidewall says 90psi but the Michelin chart has them between 80 and 85. Is this typical that sidewall charts are a bit high? D...

Dont use the lists the tire maker gives.
Michelin even uses a different list in Europe then America.
The EUR list comes to lower loadcapacity for the same pressure.
This means that the advice pressure would be higher, when looking in EUR list.
Best is to give me the GAWR's and GVWR of your motorhome, or better if you ever weighed those data(reading back I see you did, was it per axle or wheel(pair)
Then from tires maximum load and pressure needed for that and speedcode of tire.
Then I will calculate a pressure with as much possible reserve but still acceptable comfort and gripp.
And that will be mayby even 15 psi higher then when looking in list.
So higher then list is no problem, even better for livetime of tires, and lower chanche on tire failure.
