    Big Tars and displayed MPG?

    I have 35 inch tires on my WU Rubicon. Will the big tires skew the mpg reading on the display menu?
    Will it also make the miles traveled show as less on the odometer? TIA.

    All you need to do is reprogram the new tire size into the PCM.

    Whoever sold you the tires should be able to help - As they sold you the tires I am sure they are aware of this.

    You could take it to a dealer or buy a procal to recal.

    I get so ****ed off - these sellers know full well the effects of selling these items and always forget to mention or provide information or the necessary work.

    No longer a do whatever you want vehicle today they are almost AI, mods are not isolated unseen without effects.

    If you call around some dealers will do it for next to nothing. I lived near a place that sold nothing but jeeps. Mainly wranglers. He was the best shop in town even on highly modified jeeps. He did stuff like this for nothing. Good customer service gets lots of return customers.
