Trying to help out a friend. Would anyone have the factory pamphlet that was included with the truck's owners manual that listed the tire pressures for a 1998 3500 dually? I am looking for someone to send me a PDF copy. Thanks for any help folks.

Tire pressures should be listed in the door post, keep in mind that that would be the highest PSI as usually the listed PSI is for a fully loaded truck...
And NEVER exceed the tire pressure listed on the tires.
Hope that helps (got no PDF stuff)

I don't have a 98 but here is info on my 97 dually:

I found a booklet in my glove compartment labeled "Tire Inflation Pressures 1997 Light Duty Trucks Wagons & Vans" from Chrysler. It is full of charts for max load and tire pressures.

Note: The tire pressures listed below are specified for my stock tires which are (as listed in this chart and on my door jab) LT215/85/R16E for wheels 16x6 and for a RAM 3500-Dual Rear-4 Wheel Drive. I run Michelin LTX/235/85/R16E which I found the best wearing and driving tires so far that I have found.

For 3500-Dually- 4x4 chart there is a light load and full load section. Light Load - up to 2 passengers and 200 lbs cargo. Full Load - includes up to Full GVW load.

If you have 10,500 GVW Diesel (without the snow plow option) for light Load: 60 psi front (75 psi if snow plow) & 40 psi rear. For Full Load its 70 front (80 psi if snow plow) and 60 psi rear.

If you have 11,000 GVW Diesel (without snow plow option) for Light Load: 65 psi front (80 psi if snow plow) & 40 psi rear. For Full Load: 70 psi front (80 psi if snow plow), 65 psi rear.

So it looks like the door jam gives Full Load Data.

Justs adds to your confusion and mine.

Dave, thanks a bunch. Happy New Year guys. Casey

Happy New year to you. I thought I'd update my post above to indicate the size tire that I used from the chart, in case that might matter to some. Here is my added note:
