May not be the answer you want, but
The OBECM (on board electronic control module), couldn't care less what size tire you put on the jeep, could be 40"
The only thing noticeable will be your speedometer indication of speed/mileage/miles traveled
If you stay within the approx same diameter tire--don't worry about it, it's not a rolling laboratory and small errors are OK !
There are superchips/Procals-etc that do things for the jeep, but it's your money and just consider warranties--I don'tusem
