This is bad advice and please don't heed this "guesswork". Weigh your coach and adjust the PSI properly per the manufacturers chart. Timmac, please stop telling people to adjust their PSI to a random number. It's dangerous advice and frankly irresponsible.
I am not saying a random number OK, his Federal factory air specs says 80 PSI, I also have owned 2 Fleetwood's with the same size of tires and same length/weight and 80 psi is all you need, any more and it rides rough, and a few less pounds in front tires are OK and rides better as long as it never goes below 75 psi but buy most 19.5 tire specs you can go as low as 70 psi at a certain weight and 31 foot Fleetwood Flair is light in the front as was my Flair and my current Bounder, after 7 combined years riding on these tires with 76 psi in front I have never had a isuue..
And 80 psi should be the lowest setting in the rear, NO BAD ADVICE HERE AS YOU SAY :M
The point is you can't offer advice on the specs of your MH and expect it to be accurate to someone else's. Each person's MH and what they carry and how it's loaded and where they travel and the temps they travel in and the brand and type of tire are different. Therefore you can't offer up a specific PSI because you don't know their parameters. You only know yours. The sticker that came with the MH is a moot point because the tires have changed. The only way to get the proper PSi is for the owner of their MH to weigh it and set it. 76 in that case could very well be dangerously low if you find that it actually requires 85 - as an example. Throwing a number out there because that's what you do is a bit like telling me to turn up the thermostat in my house because your house is cold and they are close to the same size. It's not related and there are a ton of other factors at play. The correct answer to this question is always "weigh it and set it to manufacturers specs for cold psi". Period. The answer should never be "do what I do" or some number that you think will work.
