Bigger tires and speedo calibration?

[BBowers]

What are the tallest tires I can run in my 2003 ram 4x4 ctd? It has 33 12. 50 17's right now, and really can't afford different rims. I have the tripledog programmer but it won't let you adjust for tire size/gear ratio changes. Do any of the porgrammers? I mean on the actual speedometer, not on some monitor. The front of my truck had the 2" leveling kit put on.

35's are no problem and the smarty will take care of the pinion factor
