What PSI for tires?
After owning a few MH's this is our first FW. Airing up the tires in a MH requires knowing the weights, checking the charts and inflating to tire manufacturer specs. Max PSI was always a no-no as it c...

Yes, full max 80 psi, when cold. This will keep sidewalls firm, less flex, which results in a cooler running tire. This, part of my reason for not over tiring your trailer, then lowering the pressure. I will add, a truck such as yours, when empty, not towing, you will want to lower rear tire pressure, for better wear, and ride. A TV tire does not have near the sideways scrub of a tandem axle trailer.
Just an FYI, someday when looking at trailer again, what axle should be listed on driver's side front placard of FW. It will also have a sticker on the axle itself, if you feel like crawling under the trailer.

Lets push this a bit further here . Am I over tired , yes . Do I run max inflation ,no. Do I have a problem , no. I run off Sailuns inflation chart. My fifth wheel came with Sailun S637 ST235/80/16's from the factory. I now run Sailun S637 ST235/85/16's
As I explained to you in the PM on inflation I use. I want to be at 100 psi cold ,that gives me the same weight rating as the OE Sailuns @ 110 psi. You made me curious about heat difference if I was to run 110 psi instead of the 100. I may do just that for a short trip ,but my guess there is not going to be much difference ,certainly not something to worry about.
