Formula for correcting odometer w/bigger tires
Does anyone have the formula that will allow me to correct my odometer readings? I went from the original 265/75/16 to 285/75/16 and I want to get an accurate mileage reading. Thanks

Get your RPM (revolutions per mile) for your particular tire and then have the Dodge Dealer use the DRBIII tool to program in the new size. Its under the ABS menu, under "other", allows them to entter a number between 400 & 900. If your in good with the dealer it shouldn't cost much if anything at all.

I've done a few with the "revs per mile" and they didn't seem to get it to close at times (maybe poor info from tire source). Best way I've found is to ride along with the drb and use my GPS to fine tune the speedo by changing the revs on the DRB screen.
