You will want atleast 3.73 gears for 35's and id recommend nitto or bfg km2's. Km2's are slightly shorter but last longer, are slightly lighter and are quieter. Nittos are bigger even though they are both 35's and the sidewalls are stronger according to what ive read. Either way you will be happy with either tire choice. Mileage-- i got at best 15 or 16 with 35" nittos and 3.73's on the 12
