Attention: TDR Forum Junkies 
Material provided by TDR Member, Darren Daubenspeck:
Attached is a "How-To" document I created that explains the process of using the Chrysler DRBIII programming tool to correct the factory speedometer for different tire size for a 98. 5-02 Dodge Truck. Screens in the DRBIII make me think this procedure will work for 94-06 trucks as well.
This article was created only because A) I found a very nice guy with a DRBIII that loaned it to me, and B) my father attempted to get this fixed at his friendly Dodge dealer that sold him his truck and does some of the maintenance on it – and they told him, “You can’t adjust that on your truck. ”
I knew from reading the TDR website and magazine that this function is adjustable in the electronics, and that the dealer’s techs or service adviser was either obstinate, ignorant, or too scared to try this. So, I had to become, as read many times in the TDR, “my own warranty & repair station. ”
I realize the DRBIII is hard to come by, but they are out there. If you want this done to your truck, maybe printing this article out, determining your tire Revs/Mile on your own, and then going to the dealership may 'git 'er done' for you.
