Tire PSI in new Denali HD
 

The sticker on the door lists 60psi front and 70psi rear,

Why? Is the extra psi in the rear for the anticipated extra weight from hauling a load?

If so, is there a reason to use the higher psi if I am not doing any towing?

Or is there a reason to not use the 70psi front and rear just to keep things easy?

Id do what the door recommends, on my F250 I run the same front and rear towing or not

My 08 Dodge 2500 says 60 front and 70 rear, but I keep 60 all around and got 85K miles out of the first set of tires. Book does state that light loads the rear tires can be reduced.

On my 2500 HD with E rated tires I usually ran around 55 lbs. unload for better ride quality and would air up when towing. But that was before TPMS. You may be tripping the TPMS light running lower pressures. I'm sure this can be changed with programming.

IMHO, they ride like schit at that air psi. Our roads are brutal around here.

Set where you like it ride quality wise - we are all different - but I prefer 45lbs or so when unloaded. When loaded, I crank them up.

BTW: I can't stand TPMS.

TPMS is the devil. My wife had a Honda Accord that said to run 32 lbs. on the door sticker and it would trip the light at 30 lbs. WTF??!!!

Try being a repair shop in the northern prt of the NE.

40* everyone comes in.
15-20*F everyone comes in again.
0*F everyone comes in again.

And f*k me ! At -15*F--20*F everyone comes in again.

Repeat !

Who's the schit bag who got rid of full service gas stations ?

Errrrr.

LOL.

Nitrogen fill is the way to go IMO

I don't agree for my area....unless for race cars you you actually really need it..

I run 50psi in mine all the time. It just rides too rough with the higher pressure. I had my dealer change the program so that it doesn't trip the TPMS
