Thanks. Another reason to like AEVs. Do you think 295/70/17 would fit without rubbing?Hub Centric means the hub bore on the wheel just fits the actual hub of the jeep and is a better/stronger design then lug centric where the wheel bore is over size so they fit a multiple of vehicles. stock rims are hub centric. If you use AEV rims with 2" lift and 275/70's you will not rub.
You are correct in that the hub centricity does not transfer the load to the hub, especially in a vehicle as light as a jeep. The Hub centric design is there to ensure the wheel is centered when mounted and avoid balance issues or mis-alignment resulting in wheel hop. Lug centric wheels have been around forever too and there's nothing wrong with them, it's simply easier to ensure proper mounting with a hub centric wheel. My GMC 2500HD has Lug Centric wheels, OEM wheels were lug centric as well so not all OEM wheels are hub centric. These are 8 lug wheels though but I've never had an issue getting them mounted correctly. There's lots of threads of issues with the Jeep 5 lug wheels that are not hub centric, I'm guessing some have a larger bolt hole than others resulting in more play before tightening but the ION wheels I have on my wife's JKUR are lug centric and a damn tight fit without even putting the lug nuts on. For what it's worth the only lug centric wheels I've heard of problems with are the ProComp wheels which is unfortunate since I do like those wheels.Don't buy into the "hub centric" hype that AEV uses to sell their wheels. They are nice wheels, but that feature is not giving you anything except an advertising ploy.
Before you get too excited see if you can find any failures related to this issue. The only way the hub can begin to carry the weight is if the lugs have already failed. They don't share the load. And if the lugs have failed, the wheel is going to come off. Long ago there was a style of wheel that used a kind of flat washer to hold the wheel against the flange and the center hole to carry the weight. Not anymore. Tapered lugs have zero play and do not rely on the center hub to carry the weight.
I've found that most OEM wheels are difficult to remove and require a good whack, even my GMC 2500HD OEM aluminum wheels which are lug centric. Rotating them every 7500 miles is good for the tires and makes it easier to get them off. I've never had any issue taking aftermkt alloy wheels off the 2500HD with tons more mileage between rotations than the OEMs. 2013 stock Rubicon wheels have been rotated twice now in 12K miles and a simple palm whack on the top has done the trick so far (like stiff arming the top of the tire:happyyes.Hub centric are less universal and unfortunately hub centric alloy wheels on ferrous hubs result in galvanic corrosion and if not frequently removed can be very difficult to remove especially bad on a dark rainy night at roadside when you need a 3 foot 4x4 or a sledge to get the flat tire rim off the hub
