I'm considering purchasing a set of 18x9 aftermarket wheels w/ 275/70-18 tires for my 2015 JKU Sahara. Most of the wheels I'm considering have about 4.5" backspacing.
Am I correct in assuming that a wheel with these specs when mounted on the factory spare tire mount will not touch the existing bump-stops (or whatever they're called)? I believe the factory wheels have 6.25" backspacing so I'm assuming this means the aftermarket wheels I'm considering will be 1.75" farther away from the tailgate.
Assuming this is all correct, it seems this setup would put more stress on the carrier and tailgate. The wheel/tire combos I'm considering will also be heavier than stock. As a result of all this, I'm assuming I'm going to need a new spare tire mount.
I'm keeping my factory bumper so I'll be sticking with a tailgate mounted spare. Does anyone have any recommendations? I have come across mounts that are adjustable both vertically and horizontally. It seems like it would be good to have that adjustability to get the fit and spacing exactly how you want it no matter what the geometry of your spare may be. Any disadvantages of having an adjustable carrier?
