Tire Pressure for a 32' 3010

[Bednarski1]

I'm picking my new Rv up this week and was wondering what tire pressure most of you are using. I'll be pulling a toad most of the time and it seems like the common PSI I've heard is 70 in the fronts and 85 rears. Thanks for all the help

there should be a sticker telling you tire air pressure on the door post driver side

If it's a Ford chassis, I think you'll find 75 front, 80 rear on the sticker.

You should not be asking what others are using, but ask what is needed for your RV to drive savely for the tires.

I can calculate that with my motorhome-tire-presssure-calculator .
But need for that some information wich you can find on RV and tires.

For the tires I need Maximum load or Loadindex.
Kind of tire so Loadkind ( E-load/10PR for instance) to determine the pressure needed for the maximum load ( wich is not the maximum pressure of tire).
And best would be if you also give the speedcode presented in a letter ( N stands for max speed of tire 140km/83m/h)

From cars preferably weighed seperate wheel(pair) loads in the loading you ride with , second best is axle weighing , but in lack of those we have to do with the GAWR's ( gross axle weight ratings).
GVWR(Vfor Vehicle) is also handy .
Then the configuration of car like number of axles, and number of tires, front and back.

Then I will give a picture of my filled in spreadsheet wich gives high pressure-advices that still give acceptable comfort and gripp, but leaves as much possible reserve for things like.
Pressure-loss in time.
Little overloading in combination with unequall loading R/L.
Misreadings of pressure and loadschales ( even a calibrated schale has its inaccuracy)

Always have your rig weighed with it loaded. Then you can
add air correctly.

Best advise I have gotten from different forms.

I run 75 front and 80 rear. According to the tables I could go 70/75. I choose too run at the higher pressure. Fully loaded I'm 13500 lbs. 9300 rear, 4200 front.
