that it total horseshit!!! the PCM can be recalibrated on all models (after
97). take it to another dealer, and have them recalibrate it for you. i am
assuming that you have a 4x4 dakota, but on the 4x2 dakotas, the lowest that
the ratio can go is 723 revs/mile @45mph. i'm not sure of the heighest, but
i'm sure it's somewhere near 800. right now, i'm running 744, just lower
than the original tiresize.
the only way that the PCM can't be recalibrated is when the truck is a 97 or
earlier, because they measure the speed through a gear at the rear of the
transmission. on the 2000's, the measurement it taken digitally by a sensor
on the rear axle shaft.

Noooooo! not this again!
OK, I went to my Friendly Neighborhood Dodge Dealer at lunch today'
cause I'm about to spring for the BFGoodrich AT 31x10.5s. I wanted to
confirm with them that the computer could be reset to work with the new
tires. I was able to get them to hook up the computer to find out. He
went through the menus on his little portable and said that it COULDN'T
be changed at all! I found this to be unusual because this model truck
probaby came with several different tires from the factory. (maybe they
are all the same dia??)
He said that it all depends on which transmission is on the truck, and
the transmission that I have does not allow for changing of tire sizes.
The entry on my VIN sheet says... Transmission 4-spd. Automatic,42RE...
I was hoping someone at a dealership could confirm their findings. If
they are way off could you give me a run down on the menus as to were
to go to get this done. This guy had a confused look on his face when
going through the menus that did NOT instill confidence.
TIA
