I Stand Alone

Dually 3500

The door sticker says 65 psi. The tires of course are 80psi rated. My gooseneck probably has about 3000 lbs pin weight.
When I towed with my F450 I always ran the rears at max inflation 110psi on my 19.5 tires.

Thanks

Discount Tire told me to use max pressure ( 80 PSI ) in my SRW tires.

When empty I run 70 front and 65 rear. When towing I keep the fronts at 70 and the rears go to 80. I tried running 80 all around...for many miles and chose not to do that because the ride was a just a bit too harsh up front. Tire wear was not noticably different on the fronts at 70 or 80.

I use to run 80 PSI all around. Discount told me not to run the fronts over 70 PSI. I run BFG AT/KO's E rated in 265's

Duallies vs. Singles @ max p.s.i.?
Hmmm, I usually max 'em out when towing heavy.
