Tires! and suspension...
That's just it though. You don't need to have a dealer do it. There are private shops around here that have the computer equip and can do the recalibration for you. Maybe you could look into that out on the island and see where there's someone close to you. I'm sure you'd get a lot better price.
RonnusTwo: Why not just put on the 265/75's? it's not going to make that big a difference in your speedometer, at 100mph on the speedo you would be doing 103.4mph. That's not enough to screw you up much, if you find a place to recalibrate the speedo and you want to you can, if not it wouldn't be a big deal. You can put in the tire sizes here and it will tell you what actual speed will be at different speedo readings: http://www.discounttire.com/dtcs/infoTireMath.dos
