Thanks, yes, this is what the manual for the lift says:
IMPORTANT TIRE / WHEEL and CLEARANCE DATA
• Maximum tire width for use on factory wheels is 10.50". Factory Wrangler wheels are 17"
diameter x 7" wide with 6.25" backspacing.
• Minimum aftermarket wheel diameter is 17".
• For an 11.50" wide tire, use an 8" to 8.5" wide wheel with 3.25" to 4.75 backspacing. Ideal
backspacing is 4.5".
• For a 12.50" wide tire, use an 8.5" to 9" wide wheel with 3.25" to 4.75" backspacing. Ideal
backspacing is 4.75". With 12.50" wide tires, expect some rear tire scrub at the plastic inner
fender liners during full travel / articulation while off-roading; this generates a slight sound, but
• Maximum tire diameter is 35". For adequate clearance of 35" tires during full travel /
articulation while off-roading, minor body trimming is required at the front / lower corner of the
rear fenderwell openings. The rear ends of factory Rubicon rock rails must also be trimmed;
both trimming steps are detailed in these Instructions.
So 18x9 with 4.53" backspacing would seem to fall close to their ideal, and with forest trails and sand dunes being my planned off road locations, I don't expect a lot of full articulation. But thanks for making me reread this, I now see the part I glanced over about rub and trimming, and it shows having to cut off a triangular section of the sheet metal fender corner, so maybe I rethink this and go to a 18x9 with the 4.5" backspacing and a LT285/70R18, it would look like those would not have clearance issues, and split the difference on increased height and width.
