I used to believe that, until I moved the engine mounts forward
from the middle to what I believed a stronger position in my old Ford,
like the old Vettes used at the time. The engine stayed in the same
position, but now my car pushed rather than drifted on high speed turns.
Oh well, my old Thunderbird was never considered a sports car:

Probably at 65 foot lb. it screws right through the aluminum, the
adapter is using cone shape lug nuts to fit in the adapter lug holes,
real aluminum wheels use flat washers to hold the soft metal, and look

TJim,

I want to put wider rims and tires on. I don't know if the BFG's I have now
will expand to fit a wider rim. If not then I'll just have to wait till they
wear out to make the change. I am a Jeep newbie and have no idea what this
backspacing, lifting and such is all about.

Exactly my point. There is NO difference to what the bearing sees
for laoding between a wheel with a large offset and a
spacer/small offset combo.

As I said above, a large off set is bad for bearings (and rear
axle shafts!) but how you get there makes no difference.
