Make sure you're looking at the right sticker, there are usually two. The white placard lists GAWR and GVWR as well as tire PSIs needed to run those loads. The other sticker is a supplemental sticker showing light-load PSI. At least, there are two on my 3500. Yours should be similar, showing light-load and heavy-load PSIs.
