I needed to get my spare mounted higher ( TrailReady Rear Bumper ) to use my hitch but didn't want to impede access thru the rear window. This will also get you a litle more clearance when climbing ( used to hit my spare every once in a while in the distant past.

Just turn the spare tire carrier upside down...it will be a little higher but that will be fine ( even with 265-75-16s ) because it angles out at the top slightly...I did put two wheel spacers between the tire and the carrier also. The carrier angles inward in the stock position to allow for the curvature of the rear door. Now it angles outward at the top...not too bad at all.

Just a little something I discovered recently.
