With huge negative offset wheels, you have more leverage against the bearings. I'm trying to come up with an example that is easy to understand, but also trying to keep it simple. The only thing I can come up with are pushups. Do a pushup with your hands directly under your shoulders. Now spread your hands as far apart as possible and do a pushup. Feel that strain against your shoulders? It's the same thing with your wheel bearings. It's all leverage and physics.
Hohn's explanation was right on the money.

It's not debatable to me that there is, in fact, a negative effect on the wheel bearings from the "wrong" wheel.
But it's also possible that this effect is so small that you won't see it unless you thrash on your truck. HID uses his truck pretty hard, I'd say if it was a real-world issue, he would have seen it.
Then again, what kills bearings more isn't sustained high load-- it's momentary harsh impacts that tend to flatten the rollers. Like the kind you'd see in Baja. Like the kind of use that T-rex uses. They're a little on the extreme end of truck thrashing.
So is there an effect from the wrong wheel? No doubt. Is it significant? Probably not, but it could be depending upon how you use your truck.

Just looking at the difference in my stock wheels and my current ones.
Stock being almost 6" backspace on a 7"(8?) wheel, it looks very unevenly balanced, with the center of the wheel way towards the outside of the wheel, putting a lot of load on the outside wheel bearing.
My current 10" wide wheels with a 4.625" backspace, it looks very balanced, with the center of the wheel being very much in the center.
I would think this would be a lot less stress on the wheel bearings?
Here is a very rough drawing showing this inbalance:
[-|---] = stock wheel.
[---|---] = current wheel.
[ and ] are the outside edges, | is the inside mounting surface.
Am I totally off base here?

What do yall think about these wheels? https://www.dieseltruckresource.com/...eel1-large.jpg A member here is selling them and I really like them. Gave me a great price on them as well. I want something unique and that looks good (and so far, these fit the bill). I haven't seen anyone else around town with them.
I think the point being made is this:
[-|-*--] = stock wheel.
[---|-*--] = current wheel.
"[ and ] are the outside edges, | is the inside mounting surface."
I added a * for the wheel bearing.
Notice how, on stock wheels, the wheel bearing is almost in the exact center of wheel. When you add the extra width to the outside of the wheel, the wheel bearing is offset, multipling the forces exerted to the wheel. How much additional force is exerted? I don't know, but I hope it's not much when I get my 17x10's with 4.5" backspacing on.

Well, I'm ordering the Mickey Thopmson Eagle's in 16x10" size and the class 1 Skyjacker 4.5" lift. I'm also ordering new subs as well. Next week is gonna be like christmas.
Thanks for the help yall. I'm doing the install myself so I'll have pics of before, during, and after. I can't wait.

I think you'll be more than happy with the decision.

By the way, how much did you spend on your alarm? Which model is it?
Actually, after talking to them, I might be going with a set of Pro Comp Extreme Alloy wheels. Same style and design, but a hair cheaper. What do yall think?
Phox, my job payed me very well this past month (I guess working 7 days a week at 14 hours a day for a month straight will do that). After this, I'm broke till december (job is seasonal).
I'm finally achieving a goal I should have acheived 3 years ago. I guess I really should have listended to mom.

Right around 450(?) including installation.
