Help with tires and rims

Im changing out the tires and rims on my silver 14 polar. Already got a teraflex leveling kit and im looking for some advice. I want to do this with minimal loss in mpg's. I cant decide between 305 60 18 nitto terra grapplers standard load, 285 65 18 bfg ko2s in E rated. How much will the e rated tires hurt my gas mileage. Also cant decide on a wheel ordered fuel kranks but returned them and now im thinking fuel anza in the grayish color since my jeep is silver. Too many options and its driving me crazy any help would be appreciated.

If gas mileage is a major concern, I would look into a narrow tire. The more narrow the tire is the lower the rolling resistance it has. Look into a 255/80r17 or a similar size. This is still a 33" tall tire but has a much lower rolling resistance.

The other thing to keep in mind is weight and tread pattern. The lower the wight the better mileage and the less aggressive the tread the lower the mileage. Based off the two you posted, the BFG's should yield better mileage they are more narrow and are likely lighter than the Nittos (nittos are inherently heavy). the 34x10.5x17 KO2 is a similar size tall and narrow.
2012 Crush JK Rubicon. Teraflex 2.5" coil w/fox shocks and ATS, 1/2" front and 1" rear TF spacers. TF monster front and rear track bar, RK F/R lower arms, Ruff Stuff front upper. 315 75r16 duratracs. LOD armor lite mid w/Warn VR 8000. Lots of other goodies.
