Tire Change

How much of a power lag and mileage loss am I going to notice going from 255 to 35. Also will this require any modification? If so how big can I go with and additional mods. Have 2.5 lift and 17" wheels with 4.5 backspace.

well that could mean either 3.21 or 3.73's unless a rubicon then it could have 3.73 or 4.10's. regardless you will loose a lot of power ie giddy up but mpg may or may not take a big hit just depends on your driving style. I my mpg has not taken a hit but pickup has I have 14 unlimited rubicon with 4.10s and auto and swap between 35's and 33's and can feel a power difference but not so much a mpg difference.
