Recommended psi loaded/unloaded

Corb@CorbinShipping · Dec 4, 2011

I went from the 225/70/19.5s to the 245/70/19.5s, and now I have a nasty wash when running unloaded. Plus, I am not contacting the whole tire on the rears. I aired them down, and then aired down more...

Max psi is 110, and I am running 85 in the front, and 80 in the rear. No high heat spots when on the high way, but I drive it like an old woman. No more than 70 on the big roads. (fuel mileage.....) and only a slight shimmy at speeds. Do I need to go lower in the rear? I heard of folks dropping the pressure to below 50 in the rear, but I don't wanna rip off the hips when they blow out either....

Any help, before I experiment on my own would be AWESOME!!!!!

Thanks guys

They will wear in the middle some. I run about 90-95 in front all the time, loaded or not.
Rears unloaded I run about 60-65, loaded same as the front.
Also for the shimmy and such, look into Centramatics. They worked great for me on my dually.

Right on, I'll drop a few more pounds and see how she rolls. I just checked them out. Do they really work as good as they say?

Yes!!! I am sold on them and will put them on any dually I have.

No problem. Have fun lifting the 450 wheels and tires.
Might suggest a big pry bar to lift them on and off. Saves the back a little.

Lol! I won't even attempt it alone, I am a double amputee! I got a couple buddies, and I can afford a case of beer or two! Lol!
