    Do I have to go to the dealer to adjust for my new tires they seem to be about 5 miles off from my speedo? Thanks,

    Welcome @Leavitt4u2 ...jeepers tend to buy programmers to update the CPU. Lookup Super chips Flashcal F5 or AEV Procal as they can adjust for tire size and more. Check out a relatively newcomer JSCAN too.

    this is the job of the tire/wheel installer.

    They do install all day long you would think they have the tools?

    I gotta ask they did mention the speedo issue BEFORE selling the tire/wheel ?
