Hub / Lug excentricity
#31
I guess that is the question I've yet seen answered. Someone show me the GAWR specs pre 99 and post 99 and that they've changed significantly.
#32
Ford was changing so much from 98-99 I bet they just threw in hubcentic for good measure. I doubt it would make a huge difference, but the numbers say it's better.
#33
Why don't you post info that proves they hadn't changed? Two way street. Or do you like sounding like a broken record?

OK, here is a start. 1996 F-250 rear GAWR 6084 pounds, 2008 F-250 rear GAWR 6200 pounds.

You think that 116 pounds is going to make such a big difference? Is my record broken enough for you?

Sometimes posting some info gets you a lot farther than just jumping on someone else for answers.

1996 F250 had a D50 TTB right? Or some iteration of a D44 sized seesaw at least. Either way, not exactly a D60, there's you 2000#. 1997 brought the F250 Light Duty, and the HD started getting beefed up for the 1999.5 SD changeover. The solid D50 came along somewhere in there. Not a thing to do with the studs, they've had 8 for awhile now.

What I am saying is hub centric is a better design than lug centric and has a much better margin of safety. If you have a larger (and usually heavier)than stock aftermarket wheel/tire setup which had lug centric with tapered lugs, any imbalances could much easier make lugnuts loosen and cause a wheel separation issue than the now stock setup from ford. The current ford stock setup of hub centric wheels with the lugnuts having a flat washer with serrations built in to the lug spreads the clamping pressure over a much larger mounting area . The serrations on the washers reduces the chance of vibration loosening the lugs.
The issue of the larger aftermarket wheel/tire mounted and centered by lugs alone may work quite well for some, but the margin for error is way increased based on design.
May I also say proper spin balancing the wheel tire assembly holds a critical part of the equation also, along with starting with a tire which didnt need excessive amounts of weight to be in balance.
Recently I purchased 04 18x8 oem harley super duty rims to install on a 2000 superduty. I bought new tires for the rims, factory sized, and when they were mounted on the rims and spin balanced, one tire had excessive radial runout and the balancing machine showed besides the runout, it would have required 6 1/2 ounces of weights to even balance it, because the tire was a factory defect.
Which I am telling you about since I believe there are many trucks driving around with some sort of imbalance issue being if neglected could cause lug centric nuts to loosen by the inferior design.

In an Imbalance condition lug-centric is actually a superior mounting system as it will not allow fore and aft movement of the wheel against the hub greatly reducing the possibility of sheared studs, hub centric is a great improvement when using multi drive nut installation tools on the production line! That's why it exists, if it was to truly support the weight of the vehicle it would be more than a small ledge! It's only for assembly line speed and accuracy, regardless of what power stroke help thinks, when has he ever been right? The "volcano effect"? LoL

I really don't see what the big deal is. Plenty of people have aftermarket rims that are lugcentric. many of them tow at, or above the rated capacity of the truck
if you think your wheel will fly off, take your time and precision mount each one. while you are at it, use red loc-tite on each stud. that'll keep the lugs in place
btw, are the big rig rims that everyone seems to love hub or lug centric?
