Recommend Tire Pressure

I'm sorry but I don't trust most of what I find posted on public sites.

Check out the two sources (CapriRacer/Tireman9) you left out of my reply .......and educate yourself on the subject if you don't want to take advice from other RV.net folks.

Yep. Anecdotal subjective opinions are always better than what the professional engineers who work for the trailer makers just pull out of thin air. (Sarcastic mode off)

IF you are completely in the dark about what to do......the best place to START is with what the manufacturer suggested.
After that, it's a matter of who you trust.

What makes the most sense is to find out what the manufacturer recommends.

Is that not really available for every rig ever make.....REALLY ??

IMO what makes the most cents/sense is to listen to hundreds of experienced trailer owners who have hundreds of thousands of miles and several different trailers or simply look in on tireman9 tire blog or CapriRacer (Barry Smith on allexperts.com) and see what real tire engineers/experts have to say on the subject of tire pressure for a trailer.

The sise indicates ST tires wich are given maximum load for up to 65m/h.
then more deflection then a LT tire of same sises would have , wich is not in the market, comparable is LT 235/85R16 .
But to show why you can use 80 psi and still will have no bumping or centre wear , you can read next topic started by me.

In last posts even spreadsheet to make your own list and filled in with max/min load on tire

If then questions or you want me to help , ask it here.

Once read that tires are tested to can stand 2 to 3 times the AT-pressure ( yours E-load 80 psi) so even when filled with cold higher pressure , wich most brands allow up to 10 psi, at freesing point of water , and temp inside tire rises to boiling point of water , the tire wont reach that 2 to 3 times AT-coldpressure.

Not even when its in fact a D-load constructed tire wich is set in the market as E-load, wich I suspect is often done in America, to fullfill the American dream of bigger is better.

What about the lug nuts, ain't ya spose to check them every morning too,....and that's even when you camped ! :)

I have a factory sticker on each side of 5rv above wheels:

WARNING: Loose lug nuts can cause wheel separation and damage. Check lug nut torque on the first trip at 10/25/50 miles, check lug nut torque before every trip, check lug nut torque after winter storage, check lug nut torque after excessive braking.

So I check them with my torque wrench.
Not as frequent as indicated on sticker but whenever a wheel has been removed/reinstalled, IF I have had to do some HARD braking (rarely cause of exhaust brake) AND if having jack rig in really scrubbing tires.

Usually after 2nd re-torque don't find any loose ones.

Checking is done in AM when checking tire pressures which I run at 110#. Then recheck at first rest stop which is usually an hour and half later.

Do the same thing on truck wheels.

?

Just like on big rigs what ever the tire reads on the sidewall that's how you fill it up #___ PSI (COLD)

I hope you are not all going around corners as u may overload the outside tyers, or going op hill more load on the rear. I have newer herd a bigger load of bull. The op asked a simple question, wher are the load tables, 9000lbs divided by 4 = 2250lbs per tyer.
