Since this post is a couple of months old, this info may be too late for you. Could be helpful to others, though.

On most (all?) OBDII cars the dealer can flash the computer with the adjusted info to correct the odometer and speedometer for tire size and gearing changes. Call the dealer and ask their price, it should be reasonable (I've seen anywhere from $15 to $100).

If you would like to do it yourself, you can use products from Hypertech(not an endorsement, as I haven't used it personally) or other programmer companies, but you'll pay a bit of a premium (online price is ~$170).

Either way, if you want to have an accurate reading, it is easily done and somewhat reasonably priced.
