So after debating with myself I've decided that my next set of tires will be 37s. Currently I'm running 33s and have the following 3.25" Rough Country lift, no wheels spacers, rubicon rock rails, Poison Spyder Stubby bumper and 4.56 gears. Will they fit or will I need to do mods to make them fit? The mod I know I will need to make is to chop off an inch or two from the rock rails but besides that is I'm not sure.
