I have had my Rubicon for a bit over a year now and have about 20K on the clock. Overall, there have not been any major issues, only minor ones—wandering steering and disconnected rear window defogger being the main items that come to mind, but there is one thing that really annoys me and that is on hills/inclines and high winds, it will not remain in 8th gear.
This leads me to ask the question (or pose) the thought as to why FCA did not gear the Rubicon (OEM 33” tires) with 4.56 gears as a minimum. I get that CAFE plays a role here, but based upon my driving experience, 4.56 gears would be a help not a hindrance. Based upon the inability for 33" and 4.10 gears to remain in 8th gear, I wanted to pose these questions:
-- Is 4.56 the optimum gear for up to 34” (true OD) tires?
-- Is 4.88 the optimum gear for up to 36” (true OD) tires?
