Is having a Larger Center Bore on a wheel that big of an issue?

[wkaotp]

I'm trying to understand if having a larger center bore on an aftermarket wheel that has a compatible Hole Pattern (6x139.5) and a +18 offset is going to be a problem in any way. Does anyone have any insight for me? The center bore on the wheels I'm looking at (hub size) is 112.10.

Not usually. You can buy hub adapter rings to bring the hub size down to what fits.

Most OEM manufacturers have hub-centric wheels, meaning the hub bore is nearly identical to the wheel bore, so that the hub shares a portion of the load. By not having hub centric wheels, the wheel studs are now forced to take all of the load. Also, if you aren't really careful, bolting the wheels on can cause a vibration as the wheel isn't centered on the hub based on the bore, but rather the studs.

if you now the OD of the hub and the ID of the aftermarket wheel bore, you can go on Amazon and get aluminum hub rings to make up the difference. They also make a composite type hub ring... I've never had much luck with those lasting when changing out wheels.

I've never had a problem running bigger bores as lug centric. My new wheels are yota bore and I have no intention of using rings.

Hub centric is theoretically better than lug centric, but most people don’t have problems with lug centric. All else being equal, I might change my choice of wheels to go with hub centric if available.

Hub centric vs Lug centric… if lug wells (seats) on the wheel help center lug (tapered dish seat) and if usage on the light side… lug centric have no issues. Hub centric always preferred to distribute the weight.

If hitting wheels harder: off road jumping or rocks then hub centric would be recommended. Maybe not so important on a Bronco, more important on a Dually or Truck handling heavy loads. Definitely wouldn’t consider lug centric with heavy loads or forces on suspension.

Other variable: lug torque. If over torqued, the lugs are over stretched and have lost specified shear strength values. That greatly weakens the lugs, and lug centric amplifies that concern. Ford has pretty light lug torque values, and many commonly over torque lugs.

Not an issue as long as you have the right lug nuts (conical for most) and use the proper torque (100 ftlb for most wheels)
