I would be interested to know if this is what is affecting your drop in mileage. My mileage is pretty poor right now, averaging around 16mpg. I cant see how a wheel spacer could cause any significant drop in mileage? I have spidertrax 1.25"s on mine just for a slightly wider look with the stock BFG AT's. Before leveling the front mine would rub at full crank. Once I get larger tires I will likely take them off. Maybe this is causing a slight drop in mileage for me too as Im basically 100% stock with the exception of a Body Armor front bumper, the wheel spacers, & adjustable coilovers set to level the front.I ran four spacers and saw a drop in MPG so I took them off of the driving rear wheels last weekend. Will see.
I am suprised to here this... I wouldn't think spacers would lower your gas milage. Been running 1.25 on mine for a while but I did wheels and tires at the same time so going from 265/70/16 to 33/12.5/17 made a difference for sure.I ran four spacers and saw a drop in MPG so I took them off of the driving rear wheels last weekend. Will see.
