We have 2021 fleetwood bounder 33c what is a good psi for the tires
when loaded We will be towing a Ford ranger.

Have not a clue and anyone who does.. Except as described below. Do not listen to them.

How to get a clue.

First start with the manufacturer's recommended pressure if you can find it or anything close to (But below) the MAX pressure stamped on the tire... IE 100 PSI if the tires say Max 110.

Now find a scale.. You need a FLAT segmented scale

Loaded for travel Full fresh tank, empty waste tanks. Park so eachaxle is on a segment and get the axle weights. now pull around agains so JUST one side is on the scale and get the "That side" weight.

Now subtract the "Side" from the Axle to get the other side.

You should now have 4 weights Right and Left Front Right and left Rear.

Go to the tire maker's web site and find the weight chart for your tires.. I like to go 5 PSI over recommendation from the chart.

NOW Some folks say "All tires on an axle same pressure"

I DO NOT agree with that .. Each corner may be different.

And Duals the Inner and outer are the same.. NOTE however they have a DIFFERENT part of the maker's pressure chart.


Option to the above: go to https://rvsafety.com/

And to to the obvious link (Weighing your RV) at the top.
Small fee is worth it. They contact you (Have make, model and size of tires handy for when they call) and do all the "legwork" they come out with protable scales (Like the "diesel smokies have"and do a bunch of other stuff as well...Really nice folks.
