Tire pressure when empty

[kober]

On my 2004. 5 600 CTD 4WD Dually the sticker says to run 65 PSI front and rear at max GVW. What are you guys running in the tires when the bed is empty?

Thanks,

Kurt

I run all four of mine at 70psi

 

[lil red cummins]

45 front, 40 rear.



that is as recommended on the light load specification sheet.

Did you guys notice he has a dually?

In the dual rears 40-45 empty and 65 loaded. If you try to run 65 unloaded you will wear centers of tires on rear

I run 65 in front tires all the time.

 

[JLovas]

I don't have a dually, but I run 80 psi in all four corners, all the time. Tire tread is even across the whole width of the tire so far with 25,000 miles.

 

[JVolpe]

The front is never unloaded unless you pull the Cummins out. I learned the hard way, always at close to max psi on front.



Dont have a dully so cant say on the rear, but I do run lower in the rear tires unless it is loaded.

I know I have 45 in my front and I need to crank it up some... I can tell with a 4800 lb unloaded front axle those tires need more air!



I think I'll run 60/40.

 

[mberry]

I run 65 on all 4 corners. Not too much to be too rough, but if I put a load in the bed I don't want to worry if the tires are under inflated or unsafe. I'll sacrifice a little tire wear for that.

I run 55 up front. Unloaded.

45 Rear

65 front 50 rear.

 

[Edgemann55]

60 all the way around

I gained 1mpg running 70psi on all 4's . . Try it

 

[MFenstermaker]

I lowered my front and rears to the recommended light load hoping to get an improved ride and it did nothing - still rough on the SoCal freeways. Back to 70 all around for me.

 

[DGlover]

I run 45lbs in the rears when empty and it appears I'm still not running very hard on the outside tread. I could drop a few pounds and still be safe.

 

[macdaddy]

65 on all four corners,due to the price of fuel these days.

i run 62. 5 on the drivers side and 60 on the passenger side, to account for my weight when I sit in the truck. If i have a passenger, i add 2. 5 pounds to the passenger side, just for that trip. :--)





(no not really, just trying to sound scientific )





actually, i run 60 on all four.

 

[DPKetchum]

Do you adjust for fuel and potty breaks?

 

[Okey0]

no, but when i have all 4 dogs in the back seat, i have to add five pounds to the rear tires

Is that at sea level - or in Denver
