My 2015 Thor Miramar 34.3 has the Michelin XRV tires. When I bought the RV with about 6K miles on it all tires had 80 psi +- 1 psi. I have researched enough to know that I needed to get a fully loaded weight (full tank of gas, full fresh water, gray and black tanks, full gear and full passengers) at all 4 corners of the RV which I have done on a CAT scale using the three tires off the scale on one side and three on the scale on the other side.
My weights were:
Front left 3,860
Front right 3480
Rear left 6,740
Rear right 6,660
According to the
Michelin RV Inflation Tables my 80 psi should be about correct.
However, I have noticed that the plaque on the driver side inside wall lists the pressure as 90 psi.
I am assuming the Thor recommendation on the plaque is a general recommendation. Am I right to follow Michelin's recommendation or should I be running 90 psi?
