Hub Centric Rings Needed?
Looking to put new wheels on my 2021. Specs show it has a hub bore of 124.9mm. The new wheels have a hub bore of 125.5mm. With .6mm of difference, no ring should be needed, right?

correct, your new wheels should be lug centric by design.

I’d love for a Ford engineer to chime in on this one. Back in the day I was told to never go lugcentric on a truck this big. I was told the OEM wheels were hubcentric for a reason. The engineering might allow for lugcentric rims. I just can’t imagine they are as stout as a rim centered and supported on the bore of the hub.

Not an engineer here but I put my trucks and SUVs through a good amount of off road time. This is a big reason why I never consider anything but an OEM wheel.
I refuse to trust anything lug centric in a precarious situation. Lugs were not made for that.

There are billions of miles put on trucks with lug-centric wheels every year. They do just fine.
Yes, a hub-centric setup will be stronger, but the lugs on these trucks are plenty strong enough to handle what the truck can handle.

I was thinking the same. 8 lugs at 150 ft. lbs each - those things aren't going anywhere. With that said, probably not better than hub centric short of welding the wheels on.

I only run hub centric OEM wheels on my stuff. Good read on the topic -

You will not likely get a Ford engineer to response other than to say use the rim the vehicle comes with, anything else would be a liability. It was designed and sold using hub centric wheel for a reason. Most of the time it will be fine, but what if your are maximum payload and hit a large pothole, would you feel more comfortable knowing the impact was being taken by the lugs and studs or by the hub, lugs and studs?
Also, the proper lug not torque is 165 ft-lbs.
