I own a 2011 3500 DRW and I tow a fifth wheel with 3000# pin weight. I scale about 7000# on the drive wheels. I'm not concerned as I can scale 9350# on this axle but what tire pressure should I run? My tires say max inflation is 80psi loaded for 2835# max dual. My door stickers say 65psi max and 40psi light. I'm confused. I've always gone with tire manufacture in the past and had good luck tires. Any help is appreciated.

 

I did some research and fornd the answer to my own question. This is a great resource.

But what makes it lower rated when use as a duall tire vs a single application??Same tire single goes over 3000lbs

 

All tires are rated like this. Check the stamp on the tire side.
