Im trying to figure out what size tire I can fit on my 2004 Dodge Ram 2500 diesel truck. Im not going to be using the stock wheels. I would like to get some offset wheels. Any suggestions on what size would best fit.

Also, if i get a 2'' leveling kit for the front, how big of a setup could i run without rubbing. Any suggestions would be great

 

Check the FAQ section, it has all the information you need about tire sizes and fitment.

 

Actually I'm not sure if we have the fitments for 2500 trucks there, at least I don't remember doing them, not sure if anyone else has.

You have a smidge more height than a 1500, do to the heavier suspension. You should be able to clear 35's with 2" of lift and a good offset wheel.
