You need to air them up to 80 PSI, your camper is heavier than you are giving it credit for. Underinflated tires overheat and eventually you'll have a blowout.

I agree that without weighting loaded truck, it is safer to inflate single rear to max and eventually adjust it once you know the weight.
On my dually on other hand front requires more psi, than rear.

If you yust give me , GAWR's , always on a sticker somewhere, and if single or dual- load behind. Then I will calculate for that, and you are pretty safe.

And yes, if dual front often max and rear liwer, and if single behind, often rear max and front lower.

And if you have those agressive profile-blocks, can you comfirm that
GVWR , and max speed you use would be nice, but not that important.

Not knowing exactly what my weight is until I go back to the CAT station, we settled on 65 PSI for the front tires and 75 PSI for the rear tires for the time being. Driving from the dealership to my cousin's house (about 30 minutes) was a breeze. In fact, it was more comfortable than driving without the camper. I dialed the Rancho 9000 rear shocks to "max" or "9." I also have Torklift upper StableLoads, and the truck had a factory-installed rear sway bar (puny compared to the Hellwig, but seems to do the job for now).


Sounds about perfect! Motor on!

Okay, you buncha nervous Nellies sufficiently spooked me, and I upped the PSI in the rear tires to 80. I go to the CAT scales next week. Wish me luck.

I went to the CAT scale today with all my gear, full tank of diesel, full cassette reservoir (3 gallons), and full fresh water tank (40 gallons). Looks like I'm under my GAWR for the axles, but very slightly over GVWR.

MG1912, now that you know your axle weights, you can go to the link I provided earlier and find that the manufacture gave you the correct air pressure response to your initial inquiry.

You don't need 80 psi as some suggested.
