Im at work and just now remembering to ask this question. Don't have exact spec's, but maybe those in my situation have already done this. I want my Ram to have the same size big boy tires that the Hemi has. Yeah I have to general cookie cutter tires that came with the V6. Has anyone made the upgrade and took it to the dealer for a computer tweak? Any noticeable drops in MPG?
